Thanks for your answer. Those are three forum examples: https://forum.proxmox.com/threads/cant-restore-vm.97633/#post-437269 https://forum.proxmox.com/threads/problems-at-restoring-a-vm.93367/ https://forum.proxmox.com/threads/unpacking-vm-backup-in-ztsd-format-error.75706/ Of course...

In this forum, there are many cases of backup corruption related to ZSTD. The discussion has never gone deep. All my backups on different simple XFS volumes are corrupted. This has never happened in the past with gzip or lzo. Maybe this page could suggest that ZSTD is unsafe to be used...

This article could suggests that ZSTD compression should be avoided https://github.com/facebook/zstd/issues/2852

I'm having the same issue, from an 8TB internal HDD XFS formatted. 4 (of four) backups are unrestorable. I could understand a single corruption but I can't believe 4 backup corruption. That could be a problem with ZST? The backup process was declared as OK in all the cases by proxmox. When...

Thanks everybody, I tried everything here but in my case, I'm always getting "missing libcc_s_seh-1.dll" Renaming: libgcc_arch_lib to: missing libcc_s_seh-1.dll made the "c:\Program Files\qemu-ga\qemu-ga.exe" -s vss-install work, but proxmox doesn't recognize it. .... In the end, the final...

ZFS is also an issue .... Please do you have a quick fix?

Hi JohnTanner how it's gone your overall experience?

ZFS looks slower than anything out of the box in Proxmox. In my case is unusable. Just moving the virtual disk to a single XFS HDD gots workable results. The RAIDZ 4 SSD zpool was so slow to put the VM on it, unable to work. So ZFS is able to make slower what is physically faster. Otherwise, I...

Sorry. I moved away from Ceph all my VMs. Now that is empty, it sticks on an unhealthy state. I could figure out that the unbalanced state is due by the SSD I added to unlock its frozen state. I added the SSD with a USB dock and it was recognized by Ceph as HDD. The performance was awesome, but...

The Ceph pools are empty, there are no more VMs but there is some log maybe. The last OSD doesn't want to be stopped, without giving any reason. Proxmox 6.1-7

I added another 480GB SSD. Now the pool is about 480GB * 4. The actual busy space is less than 70GB. The CEPH storage now is stuck in this way:

Well, ok, there is a way to make CEPH recover, just one time?

Same problem for me, and it doesn't look to start recovery at all. root@pve01sc:~# ceph -s cluster: id: 56c01ca1-22ee-4bb0-9093-c852ae7d120c health: HEALTH_ERR 1 full osd(s) 1 pool(s) full Degraded data redundancy: 535023/1781469 objects...

3pc Ironwolf 8TB mobo SATA connected Xeon 1230v6 32GB RAM less than 4TB used in the pool

Thanks for your suggestion, at the age of my last message I ended putting in another 8TB HDD and starting a resilvering that has going on for a week!!!! Now everything is OK an my pool is made of device by IDs. Why is the resilvering a so slow process on a modern XEON machine (not so much busy...)?

Hi There, some update. Stopping the VMs was enough to make me able exporting the pool. But in some way it has imported it again on its way: zpool export zfs3x8TB root@pve01sc:~# zpool status pool: zfs3x8TB state: DEGRADED scan: resilvered 6.97G in 1 days 15:50:08 with 0 errors on Fri Feb...

Thanks for your advice and remarks. I started using ZFS many years ago with Nas4free, I know it is a full-featured, very interesting project. The story achieved from years of ZFS related forum reading also taught that when the zpoll is the boot device it could become a full-featured nightmare...

Hi Fabian, thanks for your suggestion. How do I put offline the pool correctly? Stopping VMS ok, but then? Are you thinking to edit Proxmox GUI to build the pools directly by disk IDs?
