Yep, this is a bug and exists in kernel 6, its still not fixed.
Only work around is to boot kernel 5. Its a pain but has been around for a few months.
i should also mention we have an NVMe pool, this is working fine.
In summary
4 x nodes
128 GB Per node
Proxmox 7.4-3
Kernel 5.15.104-1-pve
10Gb storage network
2 x 4TB SSD for ceph per node
1 x 1TB NVMe for ceph per node
1 x 1TB NVMe for local per node
1 x Ceph-ssd pool
1 x Ceph-NVMe pool
Hi,
has anything changed with the latest build of Proxmox / Kernel that would of caused high disk latency with AMD Sata Controllers?
We have a 4 node Ceph cluster with 2 x Samsung EVO 4TB 870s in each node , its been running great with fast read/writes for over 2 months, however we were made...
did you get to the bottom of this? i have the same issue, it was running fine, then over night we are seeing high latency across our SSD pool. 8 drives with high latency but its not consistent.
I don't think it can be the pbs server as when checking during backup its hardly doing anything.
Is there a way to slow the backup down on the pve server?
i have been using snapshot mode anyway, but sadly this isnt working out.
So as a test i have been using nas nfs backup using gzip, so far no issues. So it seem when using ZSTD the issue starts.
Also with PBS, we cannot select a compression so i guess it is also using ZSTD.
its not one disk? The PBS server is on a 3 disk array.
The issue is that the backup will seemingly run ok, then suddenly the writes drop to 0kb and the IO wait time and load increases significantly on the pve server.
Originally we had a 2 disk stipe on the NAS server, we never had one issue...
Hi,
did you get anywhere with this? we are also experiencing this issue. We have tried using PBS and also to the NAS itself on a seperate 2 disk stripe. the backups work ok, then all of a sudden IO delay jumps up and all VMs become unresponsive.
We never had this issue on V6, it only seems to...
Hi,
i just created a new backup server, created a new ZFS pool which is over 5TB in size. When i create a datastore its only using 194GB. Is there a way i can make the datastore larger?
thanks

its a bit weird, we have a few other Windows VMs and they are not having this issue. The 2 Windows VMs in question are non production, the rest are production (luckily). I cant see anything that is different in the config. I will also add the ones that are working have IDE CD ROMs.
Initially...
Hi,
just to add here. Upgraded to 7.1-5. There are 2 Windows VMs that boot, then after around 2 minutes become unresponsive. We have removed the CD drives completely but doesnt make any difference. HDs are using Virtio.
thanks
