Problem deploy cluster on prem about ydb

[mvgorbunov]

Hi!
It't not a good idea to use ip-address in configuration files as they can be changed, better to use FQDN that can be resolved on every node.

Caught exception: ydb/core/driver_lib/cli_utils/cli_cmds_server.cpp:349: cannot detect node ID for ydb1:19001

Did you follow on-premise deployment documentation while configuring multinode cluster? Could you show your configuration file and server startup command line?

[aHsirG]

config.txt
Config.txt is renamed "config.yaml"
comand
/opt/ydb/ydbd/bin/ydbd server --tcp --yaml-config /opt/ydb/cfg/config.yaml --node static
--grpc-port 2135 --ic-port 19001 --mon-port 8765
--log-file-name logs/storage_start.log > logs/storage_start_output.log 2>logs/storage_start_err.log &
or
/opt/ydb/ydbd/bin/ydbd server --tcp --yaml-config /opt/ydb/cfg/config.yaml --node 1
--grpc-port 2135 --ic-port 19001 --mon-port 8765
--log-file-name logs/storage_start.log > logs/storage_start_output.log 2>logs/storage_start_err.log &

I am look with example https://ydb.tech/ru/docs/getting_started/self_hosted/ydb_local from sh

[mvgorbunov]

/opt/ydb/ydbd/bin/ydbd server --tcp --yaml-config /opt/ydb/cfg/config.yaml --node static
--grpc-port 2135 --ic-port 19001 --mon-port 8765
--log-file-name logs/storage_start.log > logs/storage_start_output.log 2>logs/storage_start_err.log &

This should works fine.

I am look with example https://ydb.tech/ru/docs/getting_started/self_hosted/ydb_local from sh

You'd better use example config mirror-3dc-3-nodes.yaml
Please note - for fault tolerant cluster (mirror-3 erasure) you must have at least 3 nodes with 3 disks (block device or file on filesystem). Also you can specify only one disk per node and use erasure: none, but if one of the node fails - your database will be unavailable.

[aHsirG]

Please check my problem on single node.
If using FQDN node started with error
Caught exception: ydb/core/driver_lib/cli_utils/cli_cmds_server.cpp:349: cannot detect node ID for ydb1:19001
If using hostname node started - it good for single node, but if using cluster with hostname not work (view my first post)
command.txt
config_not_work.txt
config_work.txt
error.txt

[mvgorbunov]

You should specifiy host name in configuration file same as you get it using hostname command.
So, if you want to use FQDN (and it's nessesary for multinode cluster to communicate between nodes) configure your server host name with FQDN (sudo hostname ydb1.ru-central1.internal or add to /etc/hostname), then use FQDN in configuration file.

[aHsirG]

Good, interconnect it fixs, but next problem

in config, a change only host names (
config.txt
)

This config assumes using 3 raw block devices that were already formated as described https://ydb.tech/en/docs/deploy/manual/deploy-ydb-on-premises#prepare-and-format-disks-on-each-server-%7B#-prepare-disks%7D
If you use local data file - replace drive: path in configs on all nodes.

[aHsirG]

I am created 9 disk (for 3 machine) and using command for mount
sudo parted /dev/nvme0n1 mklabel gpt -s
sudo parted -a optimal /dev/nvme0n1 mkpart primary 0% 100%
sudo parted /dev/nvme0n1 name 1 ydb_disk_01
sudo partx --u /dev/nvme0n1

[mvgorbunov]

You have misconfiguration - you labeled disk as ydb_disk_01 but used /dev/disk/by-partlabel/ydb_disk_ssd_01 in config.txt (this is our misspell in the documentation and we will fix it, thank you for the report!).
The easiest way to fix it now is replace ydb_disk_ssd_0[1-3] with ydb_disk_01 in your config.
Also don't forget to format each labeled disk using sudo LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/opt/ydb/lib /opt/ydb/bin/ydbd admin bs disk obliterate /dev/disk/by-partlabel/ydb_disk_01 command for every disk on every server.

Its not work correct
sudo groupadd ydb
sudo useradd ydb -g ydb
sudo usermod -aG disk ydb
after
sudo chmod 777 /dev/disk/
sudo chmod 777 /dev/disk/by-partlabel
sudo chmod 777 /dev/disk/by-partlabel/ydb_disk_01
sudo chmod 777 /dev/disk/by-partlabel/ydb_disk_02
sudo chmod 777 /dev/disk/by-partlabel/ydb_disk_03
cluster correctd started,
now, simple testing and close issue

[mvgorbunov]

It's not a good idea to give 777 premissions on /dev/disk. We tested on Debian systems and it's enough to add user ydb (under which server is running) in disk group.

[mvgorbunov]

@aHsirG Everything works fine? Can we close this issue?

[aHsirG]

All fine)
My problem with permission on Ubuntu, i am not tested on Debian for undstanding problem with permission only ubuntu or my mistake.
Will check on Debian in a few days.

[aHsirG]

After retest
sudo groupadd ydb
sudo useradd ydb -g ydb
sudo usermod -aG disk ydb
it good work on Debian and Ubuntu, but need restarting VM.
I did not know this because I am not a unix administrator.

Thanks a lot for your help!
