Hi Bryan,
We started to upgrade our cluster from PVE 7.2 to 7.3 yesterday.
I have enabled the agent in our only VM with Debian 11 running on a
7.3-4 node at the moment, and performed 5 full backups in a row, VM
continues working (no hang).
This is replication, but I believe it's the same.
Some of the qemu-agent commands are the same, yes. We don't use
ZFS/replication, that's the reason I tried with backup.
You haven't provided details about your setup:
- Server (especially CPU model). Debian could be suffering from weird
BIOS clock issues.
The Hosts are HP DL360's Generation 7. ZFS Raid2 local storage using
1.6 TB SAS SSD's. The life used indicator is now 6% or 7% on most disks.
Those are quite old, is BIOS updated?
- Running kernel on PVE 7.3-4 . Kernel 5.15.x has been quite bad for us,
have you tried kernel 5.13 or 5.19?
I reverted to 4.9.0-19-amd64 #1 SMP Debian 4.9.320-2 (2022-06-30)
x86_64 GNU/Linux Kernel on the guest OS and it's not locked up once
now. This is running either the 5.2.0 or 7.2.0 agent.
Can you check TSC/clock related messages in syslog with new and old
guest kernel? Something like "Marking clocksource 'tsc' as unstable
because the skew is too large:".
I've moved the VM's across hosts and they have the same problem.
FingerlessGloves mentioned there was the possibility of this being a
mariadb issue and I can confirm we have the official Maria DB packages
installed on this server. 10.10.2-MariaDB-1:10.10.2+maria~deb11 is
what we're running on the server.
Could this be some interaction of new kernel and new maria db?
No idea, all our MariaDB instances are from Debian official repos.
Cheers
