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.

Hello, my Proxmox server had 32GB RAM but it turns out that it's not enough, so I removed all RAM modules and insert a new modules, now I have 64GB RAM, but Proxmox is rebooting after couple of seconds. Memtest not found any problem with RAM. Is there some parameters that should be rewrite or I...

I fully understand what you mean. Now my Proxmox seems stable, arcstat shows about 10-16GB available. Workload is stable too, except time when the backups are in progress. I am aware of potencialy the same crashed could happen in the future, if my workload will rise. Unfortunately I don't have...

Perhaps, but I have 32GB physical RAM and runs one VM with 16GB RAM and it seems to not enough for ZFS writes. After reboot I saw about 16-12GB available in arcstat, but when my VM starts a database backup, its down to even -285MB. If its not crashed it stayed on about 300-400MB available. But...
