4.3 upgrade Error: Check of pool qubes_dom0/vm-pool failed

I had a 4.3 upgrade Stage 3 failure where an old kernel-qubes-vm package couldn’t be removed. I fixed that issue and manually removed the package. I then manually ran the remaining commands (systemctl preset-all and systemctl enable) from the Stage 3 part of the upgrade script.

I rebooted into Qubes 4.3 to complete Stages 4-6. After rebooting, none of my qubes are able to start. If I manually start a qube, I see this error:

Error: Check of pool qubes_dom0/vm-pool failed (status:64). Manual repair required!
Aborting. Failed to locally activate thin pool qubes_dom0/vm-pool.

How can I troubleshoot or fix this?

I successfully ran lvconvert --repair qubes_dom0/vm-pool. It showed a warning while running: WARNING: Sum of all thin volume sizes exceeds the size of thin pools and the size of whole volume group but still completed.

I rebooted and my qubes started normally. I continued with Stages 4-6 from the upgrade with no issues. I rebooted again and no issues.

I’m concerned about the warning since I also saw it earlier in the upgrade during the dom0 snapshot. It’s unclear if I should do something to address the warning or ignore it.

I had the same error as you!

I had previously run into this error during stage 3 of the upgrade process and followed the advice suggested by unman which involved resizing the space allocated for dom0.

I am not sure if that had something to do with this failed to locally activate thin pool error that you’re describing occurring later on, but I was able to fix it with your suggested methods!

I got the warning as well and it also said:

WARNING: Sum of all thin volume sizes (<1.1 TiB) exceeds the size of thin pools and the size of whole volume group (<475 GiB).
WARNING: LV qubes_dom0/vm-pool_meta0 holds a backup of the unrepaired metadata. Use lvremove when no longer required.

I am not sure how the sun of all volume sizes could be that large as my SSD is not even 1TiB large. Furthermore I don’t know how or on what to use lvremove but just as in your case, even without doing this, everything ended up working.

I would appreciate some further insight however, if anyone understands or knows more about this!

Thanks for sharing that. I had the same issue. You certainly save me some time.
