Today I had the second server (this time it was our proxmox node which is also our iscsi target) with the same error: https://prnt.sc/n5sjcb The only thing I did the past few days was to add a iscsi device to a VM on the "first frozen system" which is pointing to the storage on the "second...

Hi, ok seems I found out the reason. Here the jounal of rtslib-fb-targetctl.service Apr 01 14:40:53 storage1 systemd[1]: Starting LSB: Start LIO targets... Apr 01 14:41:03 storage1 rtslib-fb-targetctl[7178]: Loading rstlib-fb targetctl: targetctlCould not create StorageObject vm-196-disk-0...

Hi @ all, I am expiriencing the problem that targetcli is not reloading the saved configuration in "/etc/rtslib-fb-target/saveconfig.json" after a reboot. So always after a reboot you need to do the command: targetctl restore /etc/rtslib-fb-target/saveconfig.json In the man page of targetcli...

Hi, mir ist gerade aufgefallen, dass bei mir im System die block devices sowie die luns, die automatisch vom Proxmox iscsi initiator node angelegt werden, nach dem neustart des target iscsi Servers einfach verschwunden sind. Kann es sein, dass die proxmox cli den save Befehl beim Anlegen des...

Hi @ all, I expirienced a total freez of an machine a few days ago. Only a reboot helped and then the machine was running again. I do have arrount 10 of the same machines which are running since an year without any problem, and now wondering what has caused the total freeze of this one machine...

Hi, klar hier ist eine kleine Howto die ich für erstellt hatte: ########################################################################## Because the new Proxmox Version has allready implemented LIO Target support, there is not mucht to do on this site. (min version of module...

@guletz but you are writing about difference between "zpool list" and "zfs list". My question was about "zfs list" for volume sizes and pool available space.

@guletz thx for your answer. Please consider the whole question because the one part, which you copied is totaly clear.

This is fully clear to me. And that is also what I assumed until now. zfs list = showing approxmiate available (usable) pool space. The thing I do not unterstand is at the same command (zfs list), the size of the volume? How "zfs list" is showing at "available pool space" the approximate...

Sorry @wolfgang to bother you so much, but I don't understand this, because you wrote: But zfs list on raidz (1 and 2) is showing me the usable space too and not the raw space NAME USED AVAIL REFER storage 44.4T...

Hi @wolfgang, Hi @ all, I am still trying to understand this stuff because it makes somehow no sense to me. It really seems that the sizes are different because of parity bits. raidz1 = 59.3G raidz2 = 74.5G raid10 = 35G But why then I cannot use the 72.5TB RAW disk space of the storage...

Hi, thx for the answer. That's what I first though too. But shouldn't that be shown in "ZFS usable storage capacity" instad of "Zpool storage capacity"? NAME AVAIL USED USEDSNAP USEDDS USEDREFRESERV USEDCHILD storage...

Hello @ all, I did tested now pve-zsync to make some backups on my new backup server but have problems with understanding the used space of the volume backup. Here the config of the node: NAME PROPERTY VALUE SOURCE rpool size...

Hi @ all, is there a default "limit" value set in pve-zsync when I do not add the option "-limit"? Because the transfer somehow seems to be limited to 1GB, even if I did not setup lo "limit" option. Regards

Ok, so that means I would have to do a live migration to a second node, then update all, reboot and then migrate back. This is exactly what I do actually. Though just there is maybe a better way. Thx

Hi @ all, I am asking myself when a server really needs a restart after a "apt update & apt upgrade & apt dist-upgrade"? For example having a server with version pve-manager/5.3-5/97ae681d (running kernel: 4.15.18-9-pve) Ok sure if I upgrade the kernel to the newest "4.15.18-10-pve" I would...

Hi LnxBil, thank you for the detailed answer.

Hi @ all, I am experimenting with KVM Linux Guests (Debian) and asking myself if it really makes sense to have Linux guest OS use Page Cache at all? Because, as I understand, ARC should do the exactly same stuff directly on the node, right? But how to disable it at all in the guest, as sysctl...

OK, thx for the answer
