Hello! We have PVE 8.1.4 and PBS 3.1. Our PBS freezes for two days in a row while the backup is in progress. At the same time, the VM that is being backed up freezes too. If I try to restart this VM, an error message "TASK ERROR: VM is locked (backup)" appears. If I restart the PBS, the VM will...

Thanks a lot! This is exactly what I was looking for

Hi! Is it possible to get current values of dataceter resources from CLI? Like on Search in GUI Thanks

I have 5 SSD disks connected to P420i in HBA mode on DL380 Gen8. Each disk produces about 420 IOPS on 4K blocks. I ctreated a ZFS pool RAIDZ1 on them. But I don't understand why the performance of ZFS pool is so poor. Why each disk is loaded the same as entire ZFS pool. And what...

I found the cause. I switched P420i to HBA mode and tested all the disks. it turned out that three of them have been degraded. iops : min= 376, max= 474, avg=461.68 iops : min= 380, max= 478, avg=460.37 iops : min= 370, max= 472, avg=459.93 iops : min= 26...

New Samsung SSD 860 EVO on P420i FW v8.32 It looks like it is. I'll try to research in this direction. Thanks for the tip.

Hi! My PVE 6.2 worked a few months without any problems. But three days ago the latency of the disk subsystem increased dramatically. PVE is installed on HPE DL380Gen8 with RAID6 on 8 SSD 2TB. No action was taken on the server when the problem started. There are no suspicious messages in the...

I even restarted the PVE node. The volume was not automatically mounted. I recreated the store, it was mounted automatically immediately, but I see the same errors in the GUI again. And showmount shown NFS share, but not CIFS. # df -h /mnt/pve/VMBackup2 Filesystem Size Used Avail...

Hi! I have PVE 6.2-11. I created new CIFS storage from FreeNAS. Now I see it from shell on PVE host: #df -h //st-nas1/VMBackup2 5.2T 5.0T 214G 96% /mnt/pve/VMBackup #mount //st-nas1/VMBackup2 on /mnt/pve/VMBackup type cifs...

Hello. Why PMG is case sensitive to email addresses?

Ok. I set recordsize to 4k and turned off compression, but zfs still writes to disks several times more than it needs. root@vmc3-1:/nvmepool# smartctl -a /dev/nvme0n1 | grep Written Data Units Written: 770,603 [394 GB] root@vmc3-1:/nvmepool# smartctl -a /dev/nvme1n1 | grep...

My server has 320 GB RAM, but nvme disk is only 450 GB. And how it explains that zfs writes to disk 25 times more data.

Look at numbers above. When fio writes to zfs volume 1 MB, zfs writes to disk 26 MB. Why?

Hi, I have similar problem with zfs. Can anybody explain me, why fio shows bw=30249KB/s, but at the same time iostat shows 797297.60 wkB/s?

Is it possible? I tried, but with errors. # pvecm add 10.1.0.11 copy corosync auth key rsync: change_dir "/etc/corosync" failed: No such file or directory (2) rsync: link_stat "/etc/pve/corosync.conf" failed: No such file or directory (2) rsync error: some files/attrs were not transferred (see...

Hi, I have the stable issue. Crystal Disk Mark hangs VM in 100% of cases when VM is launched on PVE 3.4 with kernel 3.10 and VM's disk is qcow2. With kernel 2.6 or any other format of disk no such problem. When I stop the hanged VM I get the next messages: root@hq-vmc1-1:~# qm stop 121 VM still...
