Buffer I/O error on dev dm-3, logical block 0, async page read about ovirt_simple_backup

I will add the "dmsetup remove_all" as described. Does this get around the issue so that it no longer requires LVM names to be unique? I didnt run into issue and some of my VM's are made from the same templates.

you still need to have unique LVMs names, is not bug in your software is the way how OS is working so is why should be only mentioned in installation manual
Thank you

;) I will add a note to the docs. Thanks for pointing out the issue ;)

Hello,

I experienced the same problem, the solution that worked for me was to prevent lvm from scanning any disk other than /dev/sda

in /etc/lvm/lvm.conf add
global_filter = [ "a|/dev/sda|", "r|/dev/sd*|" ]

Seemed simpler than making sure all lvm names are unique.

Thanks doe-cu, I have added your comment to the docs ;) Will post on next push.

Hi all,

Sorry it's an old issue, but I had the same today and for information, in my case, it was a RAID controller issue.
I replace the RAID controller with the same model, I imported the configuration of my 8 disks in RAID 5 and now it works.
Sometimes, the problem is the hardware... but for a 11 years old server it's not to bad. :-)
Best regards.
