jsterr reacted to Sim0n's post in the thread [SOLVED] Is a vzdump backupjob on a slow nfs-server able to trigger watchdog with Like.
Maybe the the IO-Wait gets so high that corosync drops out or the Watchdog gets triggered? You could try to set a bandwidth limit in the backup job or a fleecing storage? -
hloudes replied to the thread How to configure DSCP ?.Hello, Thank you for your response. Is the version now available? Thanks again, @j.theisen, for the quick diagnosis you provided via the ticket. I won’t hide the fact that I had to switch to prioritizing the entire VLAN via TC and disable the... -
Rrvencu replied to the thread Datacenter Manager API Dev Guide.Thanks, this is very useful. As we developed for clouds until now, we did not need a local lab. It is difficult to build one since we do not own a datacenter but I would like to rent some lab where I can test and debug our integration with...

MMatheus Alexandre replied to the thread Intermittent I/O errors on SAN-backed VM disks (Proxmox VE 9.2).Thank you for your insights! That's a very good point regarding the possibility that the I/O error could be occurring at the QEMU layer rather than in the FC, multipath, or LVM stack. I also agree that moving the backup window to Saturday would...

MMatheus Alexandre replied to the thread Intermittent I/O errors on SAN-backed VM disks (Proxmox VE 9.2).Thank you for your suggestion! That's a good point. I'll check with our backup team to see whether it's possible to move one of the affected VMs to a different backup day so we can observe whether the issue still occurs. I'll gather more...

MMatheus Alexandre reacted to bbgeek17's post in the thread Intermittent I/O errors on SAN-backed VM disks (Proxmox VE 9.2) with Like.
I am not familiar with how Bacula integrates with PVE. If it operates through the QEMU layer, similar to PBS and Veeam, it is possible that the I/O error originates at a higher layer than FC, multipath, or LVM - that is, within the QEMU layer...

MMatheus Alexandre reacted to longer's post in the thread Intermittent I/O errors on SAN-backed VM disks (Proxmox VE 9.2) with Like.
My first thought was if there's backup running during that time, and I kept on reading until spotting it: "Our backup infrastructure uses Bacula, and backups are executed on Fridays, so I'm wondering if increased I/O load could somehow expose an...

I think a slow nfs can absolutely be a problem in that case, how fast is it?

OOnslow replied to the thread [SOLVED] W: Couldn't identify type of root file system '/dev/pve/rootu/dev/pve/root' for fsck hook.Most likely this is some typo or an erroneous pasting during editing fstab. As this path doesn't exist, just comment out this line in fstab. Then run an update as usual and verify that the warnings are gone :).
