drbd-utils's Introduction

DRBD Utils

This repository contains the user space utilities for DRBD.

DRBD, developed by LINBIT, is a software that allows RAID 1 functionality over TCP/IP and RDMA for GNU/Linux. DRBD is a block device which is designed to build high availability clusters and software defined storage by providing a virtual shared device which keeps disks in nodes synchronised using TCP/IP or RDMA. This simulates RAID 1 but avoids the use of uncommon hardware (shared SCSI buses or Fibre Channel).

Using DRBD

Please read the user-guide provided at docs.linbit.com.

Build drbd-utils without sudo privilege

Dear DRBD comminity,

I am planning to use drbd in my project and I want to compile and build it from drbd-utils repository. I use Ubuntu 20.04 as an environment. While processing make install command, it creates symbolic links and directories into root directory which is also defined as destination directory in Makefile. Is there any way to change destination directory (DESTDIR)? I want to use it without any sudo privilege.

crm-unfence-peer.9.sh "cannot parse input" when trying to unfence resource

DRBDADM_BUILDTAG=GIT-hash:\ 9f2aa37\ build\ by\ [email protected],\ 2021-11-14\ 18:45:36

DRBD_KERNEL_VERSION_CODE=0x090104
DRBD_KERNEL_VERSION=9.1.4

when a resource location constraint has been placed for a resource on a node, if at some point drbd try to unfence the resource, it cannot , and drbd resource cannot be promoted anymore on the node ,

error seems to be the call to sudo cibadmin --modify --allow-create -o constraints -X "" (called from create_or_modify_constraint)
(note the empty data "" at the end). Indeed the new_constraint value in the bash script does not seem to be ever set,

RPM build is broken

Hi,

This commit c3ac818 removed the RPM targets in the Makefile.

As such, the instructions in the docs to run make rpm are no longer valid for the latest versions. How should RPMs be built?

Thanks,

DRBD selinux policy doesn't work when attempting to create the metadata storage

With Selinux enabled on my systems I load the drbd-selinux rpm. But when i attempt to create the metadata file using drbdadm create-md it runs into selinux permission denies for accessing the disk where the metadata storage is written to. This issue also happens when you try to delete the metadata storage. I am unsure if this is an oversight in the selinux policy or if there is something else that I am missing with the drbd-utils.

9.2.6 : make test : failure

Hello,

I have been exploring building out the drbd stack (kernal,reactor and utils) on debian bookworm.

I have tried a few different configure params to see if anything helps, but nothing seems to avoid this error.

Anyone have any ideas, what is casuing the failed test, or even better how to correct the issue?

snapshot-resync-target-lvm.sh cannot create a thin snapshot

In snapshot-resync-target-lvm.sh, the snapshot is created like so:

lvcreate -s -n $SNAP_NAME -L ${SNAP_SIZE}k $LVC_OPTIONS $VG_NAME/$LV_NAME

Because of the -L option, the resulting snapshot will be a "thick" snapshot, even if the volume in question
is a thin volume. Is there some reason that it is done this way with no option for creating a thin
snapshot by omitting this argument?

Perhaps I'm missing something important, but it seems to me that there should be an option
to this script to omit the -L argument so that a thin snapshot could be used instead.

Andy

DRBD disk fails to mount in case of lost connection

dear DRBD community,

i have been struggling in the past days when debugging a simple scenario whereby i have 2 DRBD nodes connected in simple master-slave (single primary) mode, with protocol C.

The two nodes use heartbeat together with DRBD.

Failovers and disk mounting and replication works fine in all "controlled failover" scenarios, meaning when either heartbeat is stopped on one of the two machines or one node is rebboted / killed.

The problem is when one of the machines suddenly loses the connection (ethernet cable is unplagged), in which scenario Heartbeat starts corretly on the other node, which is promoted as Primary/Unknown but then when Heartbeat tries to mount the drbd disk using this command: mount -t jfs /dev/drbd0 /my_folder it fails with this strange error:


ResourceManager(default)[22908]:        2022/05/20_17:16:01 debug: Starting /etc/ha.d/resource.d/Filesystem /dev/drbd0 /my_folder jfs noatime start

mount: wrong fs type, bad option, bad superblock on /dev/drbd0,
       missing codepage or helper program, or other error

       In some cases useful info is found in syslog - try
       dmesg | tail or so.
2022/05/20_17:16:01 ERROR: Couldn't mount filesystem /dev/drbd0 on /my_folder
Filesystem(Filesystem_/dev/drbd0)[23231]:       2022/05/20_17:16:01 ERROR: Couldn't mount filesystem /dev/drbd0 on /my_folder

Again, i have correctly partitioned and formatted disks/filesystems, and the DRBD + HA setup works fine in all other cases.

Is this a knownllimitation of DRBD or is there any other configuration i could test?

P.S. i am using drbd8-utils on a debian8, 32bits machine. Both nodes are identical (same image + hardware).

make doc fails due to external entity docbook.xml

I am experiencing issues when building the docs for drbd-utils-9.21.0.

The problems originate from commands like

/usr/bin/xsltproc \
--xinclude --stringparam variablelist.term.break.after 1 \
http://docbook.sourceforge.net/release/xsl/current/manpages/docbook.xsl [email protected]

which gives issues like

make[1]: *** [[email protected]] Error 5
make[1]: Leaving directory `<...>/drbd-utils-9.21.0/documentation/v9'
make: *** [doc] Error 2

I saw this happening at various stages for the MANPAGES files in documentation/v9/Makefile, i.e.

MANPAGES   = drbdsetup.8 drbd.conf.5 drbd.8 drbdadm.8 drbdmeta.8
MANPAGES += ocf_linbit_drbd.7
MANPAGES += ocf_linbit_drbd-attr.7
ifeq ($(WITH_DRBDMON), yes)
MANPAGES += drbdmon.8
endif

Similarily,

cannot parse http://docbook.sourceforge.net/release/xsl/current/manpages/docbook.xsl
make[1]: *** [[email protected]] Error 4

due to the ADOC_MANPAGES files,

ADOC_MANPAGES :=
ADOC_MANPAGES += [email protected]
ADOC_MANPAGES += [email protected]
ADOC_MANPAGES += [email protected]
ADOC_MANPAGES += [email protected]
ADOC_MANPAGES += [email protected]
ADOC_MANPAGES += drbd.service.adoc
ADOC_MANPAGES += [email protected]
ADOC_MANPAGES += [email protected]
ADOC_MANPAGES += [email protected]

It sometimes advanced to the next MANPAGES file when just running make doc but then failed with the same issues.
My guess is that http://docbook.sourceforge.net/release/xsl/current/manpages/docbook.xsl drops connection after to many tries from the same IP.

A workaround I found working is to manually install docbook-style-xsl and change STYLESHEET_PREFIX in documentation/common/Makefile_v9_com pointing to the local installation

#STYLESHEET_PREFIX ?= http://docbook.sourceforge.net/release/xsl/current
STYLESHEET_PREFIX ?= /usr/share/sgml/docbook/xsl-stylesheets-1.78.1

Weirdly, the sheer presence of docbook-style-xsl seem to render the build to succeed.

Anyways I thought you might want to know about this issue or it is of help for somebody else.

user/drbdmon/Makefile.in: --pedantic-errors should be -pedantic-errors

In user/drbdmon/Makefile.in: CXXFLAGS=-std=c++11 -I. -I../shared -Icppdsaext/src -Wall -Werror --pedantic-errors -fPIC -O2 \

But according to "man gcc | fgrep pedantic-errors":
-fsyntax-only -fmax-errors=n -Wpedantic -pedantic-errors -w
-pedantic-errors
error by -pedantic-errors.
(one dash).

GCC admits the "--pedantic-errors" form, some other compilers not.
Please, change this option to "-pedantic-errors".

Please add "drbdsetup wait-disconnect*" commands as well

drbdsetup has very nice wait-connect and wait-sync commands; it would be great if there would be more of them, to more easily trigger actions in shell scripts. For example, drbdsetup wait-disconnect-resource would be nice.

Thanks a lot!

Questions and discussions about load-balance-paths

From the introduction of load-balance-Paths, I think it realizes the fault tolerance and load balancing of drbd network.
Below is my configuration file：

/etc/drbd.d/drbd1.res：
resource drbd1 {
connection {
path {
host ha-155 address 192.168.122.65:7789;
host ha-156 address 192.168.122.66:7789;
}
path {
host ha-155 address 192.168.122.155:7789;
host ha-156 address 192.168.122.156:7789;
}
}
on ha-155 {
device /dev/drbd1;
disk /dev/sdb;
meta-disk internal;
node-id 1;
}
on ha-156 {
device /dev/drbd1;
disk /dev/sdb;
meta-disk internal;
node-id 2;
}
}
/etc/drbd.d/global_common.conf
net {
load-balance-paths yes;
}

After two network paths are created, run the "drbdsetup events2 --now" command to find that the two paths are connected.

After the second network is disconnected, run the "drbdsetup events2 --now" command to find that the two paths are still connected.

After the first network is disconnected, "run the drbdsetup events2 --now" command to find that both paths are disconnected.

According to my understanding, disconnect one of the networks and keep the other one connected, but the result is not so.

What's my problem? Do you have any suggestions?

Any support for a cpu mask string larger than 32 bytes?

The existing 32-byte CPU mask string effectively limits the user to being able to specify cpus 0-111. Systems are getting large enough that they can now have more than 112 CPUs.

Are there any plans to increase the allowable size of the CPU mask string to something larger?

DRBD uses openssl or gnutls?

Hi,
I have doubt is DRBD FIPS compliant?
As DRBD uses openSSL to generate certificate but for tcp encyption consumes tlshd user land library which is dependent on GNU-TLS. Can anyone confirm what is the actual thing.

9.19.1: drbd_buildtag.sh relies on .git

The drbd_buildtag.sh script relies on .git existing:

The problem of `drbdsetup status --json`in version 8.9.10

When using the drbdsetup status all --json command in version 8.9.10(in picture 1), the prompt --json option does not exist (In picture 2), but you can see the --json option when executing drbdsetup status -h(In picture 3)

snapshot-resync-target-lvm.sh not compatible with 9.x

The snapshot-resync-target-lvm.sh script is not compatible with drbd9x.
First the snippet

                OUT_OF_SYNC=$(sed -ne "/^ *$DRBD_MINOR:/ "'{
                                n;
                                s/^.* oos:\([0-9]*\).*$/\1/;
                                s/^$/0/; # default if not found
                                p;
                                q; }' < /proc/drbd) # unit KiB

will always return zero (default if not found)

Second, if you have more than one volume configured for the same resource it will also fail:

udev links break with newer systemd versions

DRBD's udev rules don't work with newer systemd versions when the machine's hostname changes during boot, as it does in many VMs and cloud hosts. Starting with systemd version 242, the new ProtectHostname sandbox setting is enabled by default in the systemd-udevd service, applying to any scripts run within udev rules (see systemd-udevd unit file and changelog). This is impacting DRBD's udev links:

drbd-utils/scripts/drbd.rules.in

Line 6 in 1caa041

IMPORT{program}="@sbindir@/drbdadm sh-udev minor-%m"

When the udev rule executes, drbdadm sees the host's original (invalid) hostname, compares it to the hostname in the resource config, and fails:

(udev-worker)[93198]: drbd0: Starting '/usr/local/sbin/drbdadm sh-udev minor-0'
(udev-worker)[93198]: drbd0: '/usr/local/sbin/drbdadm sh-udev minor-0'(out) ''minor-0' not defined in your config (for this host).'
(udev-worker)[93198]: drbd0: Process '/usr/local/sbin/drbdadm sh-udev minor-0' failed with exit code 1.

And the /dev/drbd/by-disk and /dev/drbd/by-res symlinks never get created.

I'm not sure what the right solution to this is. As far as I can tell, there is no way to scope these sandbox rules to individual udev rules or scripts. Disabling ProtectHostname on systemd-udevd via a systemd override solves this problem. Restarting the systemd-udevd service also solves this problem, as the hostname in the UTS namespace is refreshed. Neither of those seem like tenable solutions to me.

Misspelling

There are some spelling mistakes in line 120 of the code

re_init_daemon()
{
	resources_with_existing_attributes=$( list_existing_attributes )
	resources_known_to_drbdadm=$( drbadm sh-resources )
	resources_seen_in_initial_dump=''
	status_delay=''
	exec 0< <(exec drbdsetup events2 --timestamps 9>&- )
}

The correct spelling is as follow：
resources_known_to_drbdadm=$( drbdadm sh-resources )

Conduct unbecoming from a member of the LINBIT organization

I provided a bug fix to a small bug. A bug nonetheless.

That bugfix was closed by LINBIT's member way of winning an exchange. Had he been polite from the outset there would have been no exchange.

The member promised to uplift the provided bugfix and implement it at a later date as his own, speaking volumes about his character (it does not matter if the license permits it). Linbit's member said "will apply my proposed patch". About my code, which I provided to fix the bug.

That all occurred here: #36

In spite of his conduct I have persisted and pushed another tidier single commit bug fix: #38

A historical report of the bug affecting other people:
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1030118

What did I think would happen? Something more normal, with a civil interaction resulting in a fixed bug.

Split-brain notification script not working

Hello,
notify-split-brain.sh is not sending email when SB occurs. There is missing environment variable $DRBD_PEER

From syslog:

notify-split-brain.sh[16322]: Environment variable $DRBD_PEER not found (this is normally passed in by drbdadm)

crm-unfence-peer.9.sh error in _check_peer_node_reachable()

The function _check_peer_node_reachable does not work with pacemaker-2.1.0-8.

Line 1082:

                if [[ $crmd = "online" ]] ; then
                        local out
                        if out=$( crmadmin -t $(( cibtimeout * 200 )) -S $DRBD_PEER ) \
                        && [[ $out = *"(ok)" ]]; then
                                peer_state="reachable"
                                return
                        fi
                fi

The script uses crmadmin to find out the reachable node. But it expects (ok) in the stdout if it is.

Old stdout of crmadmin was:
Status of crmd@testclust7-02: S_NOT_DC (ok)
Now, with new pacemaker version the output is:
Controller on testclust7-02 in state S_NOT_DC: ok

The () need to be removed to make the script work again.
