Hi @fiona This is the output of pveversion -v proxmox-ve: 9.0.0 (running kernel: 6.14.11-2-pve) pve-manager: 9.0.10 (running version: 9.0.10/deb1ca707ec72a89) proxmox-kernel-helper: 9.0.4 proxmox-kernel-6.14.11-4-pve-signed: 6.14.11-4 proxmox-kernel-6.14: 6.14.11-4...

Hi, same problem here. We have several servers with the same configuration, ZFS storage, and automatic VM snapshots (autosnapshot). The VM freezing problem only occurs on this latest PVE9 server. The VMs that have currently frozen are two Windows VMs (Windows 10 and Windows Server 2025), both...

I'm trying to use the sync-on-mount feature of PBS 4.0 to sync backups to external disks. The idea is to connect a USB disk, perform the sync, and then disconnect it. The operation is carried out by non-qualified personnel, simply by connecting and disconnecting the USB disks. Everything would...

I've the same question, but i think we cannot eliminate the vps. I think the only way to make the backups inaccessible is to have two PBS systems, where the remote PBS performs a pull of the backups from the local PBS.

May be a similar patch can improve sync performance between two pbs?

I use both nvme or sata ssd with lvm or zfs storage. I tested Ceph in a datacenter but noticed poor I/O performance with SQL. Your issue might be related to the combination of Ceph's low I/O and database encryption. Can you test the same hardware (single node) with a different type of storage...

Our company has been installing PVE for over 10 years, and we use Windows Server VMs with MS SQL versions ranging from 2008 to 2022 without any issues. The configuration you posted is correct. I have never used CEPH or encrypted databases, so the problem might be related to these two...

It depends on the storage you're using. Run tests with write-through, no cache, and write-back modes, and choose the one that provides the best performance. Ideally, one of the first two would be better for safe reasons.

I've a DL20 with MR216 and 2 SSD NVME in RAIDZ-1 and it is very fast. A DL325 with MR416 and 4 SSD NVME in RAIDZ-10 is fast, but not as DL20 A ML350 with MR408 and 2 SSD NVME in RAIDZ-1 has bad 4k random performance If you use ZFS raid with these controllers, the very big problem is that you...

With san, we have found that Write Throught has the best performance and is it the safest cache mode.

For a Widows vm, do i need to resize the guest partition before shrink volsize?

Interesting! Could you provide some more info on the configuration?

Reverting to kernel 5.15 does not fix the problem. May be related to qemu and not to the kernel?

I've the same experience on two server, ML380 G9 and ML160 G10. All worked fine until i've upgraded from 7.2 to 7.3 and kernel 5.19, then the vms randomly freeze with 100%cpu usage. Now i've revert to kernel 5.15, i report back if this fixes the freezes

Ok thanks, i need to create a new role with all audit permission ans Sys.syslog

Hello, i'm trying to setup a zabbix server to monitor my proxmox server, all works fine with api token with PVEAuditor permission except for the cluster/log api. It works only if i add PVEAdmin permission to api token, with only APIAuditor it report an empty array

Ok thanks, so .chunk and the others hidden folders still remain in root namespace

Hi, i have 2 pve server and 1 pbs server, now all backups are stored in the root namespace. Can i create two new namespaces e move historical backups in it? for example move vm 100,101,102 in namespace server1 and the others in server5

Have you tried this? https://kb.msp360.com/standalone-backup/general/vss-error-8194 Are there other softwares that make use of shadow copy? mssql dump or similar

Same problem here with Intel Xeon Silver 4210R, guest with Windows 2022, q35 and tpm It crash about once a week
