So could I create one LVM physical volume over the top of the OCFS2 volume directly into the /dev/mapper/STORAGE-DATA device? So basically pvcreate /dev/mapper/STORAGE-DATA and so on? What about GFS2? Do you consider it better than OCFS2? Thanks!

Thanks! I will check. In your opinion, could I make a LVM physical volume over the OCFS2 volume? Thanks!

Hi, I have 4 Proxmox servers, all connected to a Fiber Channel storage using multipath which is serving two volumes: STORAGE-DATA and STORAGE-DUMP. Every node is showing 4 sd* devices (2 per volume) and one mapper device per volume: root@node2:~# multipath -ll STORAGE-DATA...

Thanks Fabian! I cannot understand how I can solve this problem: now I'm creating a new virtual machine on another server to solve the disk problem and I don't want to replicate this problem. Could you send me some hints on what I have to do to avoid this on the new server? I've just created a...

Hi, my virtual machine has two ZFS drives, one 60 Gb and one 18 Tb: root@gus3:~# grep zfs /etc/pve/qemu-server/3001.conf virtio0: local-zfs:vm-3001-disk-0,size=60G virtio1: local-zfs:vm-3001-disk-1,size=18T I have 4 10 Tb disks on this server and I'm running out of disk space, so I'm...

Yes, it was turned off. Many years, more than 5, almost 7-8. I am using ECC memory. Thanks!

I understand that, but it's very strange that this happened after a disk replacement, isn't it?

Hi, on my Proxmox 6 system I have some ZFS pools, one of this is a raidz1 pool with 6 drives. One drive had a failure prediction on SMART so I replaced it with a new one following the guide at https://pve.proxmox.com/wiki/ZFS:_Tips_and_Tricks#Replacing_a_failed_disk_in_the_root_pool. After that...

Hi, is there a way to mount ZFS snapshots to be accessible from the VM? I know that snapshots on Proxmox are for the whole disk block and not for the single partition, but I'm wondering if there is a way to let users to access to snapshots themselves without mounting a snapshot from Proxmox...

No, I don't have a SLOG, do I need it even using SSD and NVMe drives?

Because I'm getting 10x fsyncs with sync disabled, and virtual machine are much much more faster.

Thanks. Could you help me to understand which are the possible events which causes last writes to be lost? Power interruption without UPS Hard shutdown Kernel crash on Proxmox host Kernel crash on virtual machine? Qm process or container kill from Proxmox host? Snapshot? Other? Are snapshots...

Hi, is it safe to set the ZFS sync as disabled on Proxmox 6 if I have a working UPS protection? I see that fsyncs increases a lot with sync disabled, will this corrupt some snapshot? Thanks!

Hi, I installed PVE 6 with ZFS on two SSD drives on an IBM x3650 M3 server with a H200 SAS controller cross-flashed to IT mode. The installation process ended correctly but after the reboot the server does not boot, nor in UEFI mode nor in legacy mode. If the USB drive is plugged into the server...

Hi, I have a simple question which I would like to share with because I’m interested in you point of view. On a Proxmox server I have fast storage (SSDs or NVMe) and slow storage (SAS or SATA). My fast choice could be to install Proxmox on fast storage and use it also for storing virtual...

Hi, I'm suffering this problem on two different Proxmox hosts with two LXC containers: [338962.945187] Memory cgroup out of memory: Kill process 33823 (celery) score 6 or sacrifice child [338962.946422] Killed process 33823 (celery) total-vm:212304kB, anon-rss:51236kB, file-rss:28kB...

Thanks. Just to be sure: are you referring to the following workaround? Is it correct that I should apply this on the host node for Proxmox itself and containers and on VMs? Thanks!

Thanks! Will moving to KVM solve this problem?
