I am not talking about VM/CT configs, I am looking for non existent partitions

zfs list was pretty empty, USED 300MB, the rest were AVAILABLE

@waltar I understand, but my server had no power outage at all. @floh8 I have working backups on all production environment, but I make one backup per day, so there will be always some data loosing.

Well, this is the first serious problem with ZFS I have after years of using it.

Well, I can accept a risk of NVME damage - Proxmox OS, but I don't accept loosing of all data. I don't know why this happend.

Hello, I just lost all data from my test lab server. It's Supermicro X12STH-LN4F. Proxmox VE was installed to consumer NVME SSD Patriot P300. ZFS RAID1 is placed on 4x HGST HUS722T2TAL. Slow, but functional. My server freeze in the night. I was not able to reach it, ping not working too. After...

I guess LVM with ext4 or xfs will be much faster then ZFS, it will use less RAM than ZFS, but as I wrote I never used Proxmox without ZFS. Maybe I should give a chance to that.

Hello, I am aware of informations provided by many people here in forum about buying enterprise grade SSD for Proxmox VE. But many people runs Proxmox in own homelab with low budget HW. I have for example this MB from Supermicro , now I have one M2 SSD Patriot M.2 P300 256GB (in MB) with 4x...

the time difference is an exact time difference between made a snapshot and rolled it back. So I made snapshot, waited for 6 hours and rolled back a snapshot. I did not touch timezone. It is the same VM.

Not sure what your suggestion about setting my timezone means ? Of course I have my timezone from begining of VM installation.

Hi all, I was wonder what exactly would happen when I make a snapshot of live linux VM and then after a couple of hours I will click on rollback ? I supposed that VM will be at the same state when I did a snapshot. I am pretty sure of that. But I was wonder what will happen after that. My...

I can confirm a new parameter "performance max-workers=N" has a significant effect to performance. My IO a CPU load were incredibly high when a backup was runnig, when I setup performance max-workers=1, the backup takes a little bit longer, but the load and IO are much better then before. Thanks...

CPU usage is CPU usage, but IO waits are very high too. iostat shows %iowait almost 100 and %idle almost 0. OK, I can make an upgrade and setup max-workers, but why the second server is OK during backup ? Will try.

For that purposes I am using autofs. It mounts and unmounts shares on-demand.

Hello, I have two Proxmox VE server on almost the same HW, except the installation. PVE1 was installed on 256GB NVME M2 drive + 4x2TB HDD with ZFS RAID10 for VM. PVE2 doesn't have NVME drive and OS was installed on 4x2TB ZFS RAID10. PVE2 have a subscription Production-ready Enterprise...

It seems connecting PVE to different switch solved this problem. I don't understand why, but thanks for suggestion.

Yes, the host is connected to a Mikrotik switch with vlan support. Well, the other hosts are connected to another Mikrotik switch, but all vlans are configured on all switches, but I can arrange move this host to the same switch. This could be useful tip. Intel Corporation I210 Gigabit Network...

Hello, I am strugling with vlan settings on one Proxmox VE (strange, but other PVEs runs without this error and all PVEs are configured in the same way). My config: auto lo iface lo inet loopback iface eno1 inet manual iface eno2 inet manual iface eno3 inet manual iface eno4 inet manual...

It turned out that all RAM modules are not OK. Maybe all series of this memory modules are bad. I bought 8 modules in total, 4 modules from one seller, 4 modules from different seller. Even memtest could not find any troubles. When I started my server from cold start, it runs OK, until the next...

No I cannot see anything strange while it boots. Old RAM works OK.
