yes - this loads the pool always! ln -s /lib/systemd/system/zfs-import@.service /etc/systemd/system/zfs-import.target.wants/zfs-import@poolname.service I'll with check with newer zfs versions again - if the problem still exists. Some months ago - when I last rebooted, I had no problems with...

thanks - yes the zpool cache is involved rm -f /etc/zfs/zpool.cache - reboot - works another reboot with existing /etc/zfs/zpool.cache - fails again setting another cache file for this pool doesn't help - fails so only removing the /etc/zfs/zpool.cache imports the zfs pool before the...

journalctl -b is attached. checked once again - manually starting rtslib-fb-targetctl.service works rtslib-fb-targetctl.service is loaded too early on ZFS systems who can suggest some systemd magic to make rtslib-fb-targetctl.service load after ZFS zvols are ready?

I've tried a PreExec sleep (up to 30s) in the rtslib-fb-targetctl.service - doesn't help - rtslib-fb-targetctl.service still fails.

Hello, I've activated the LIO iSCSI target on some promxox hosts for sharing local NVMe's over iSCSI (beside using those NVMe's for replicated storage) But now my LIO target LUNs are not restored on boot anymore: systemd[1]: Starting rtslib-fb-targetctl.service - Restore LIO kernel target...

Hello Fiona, my two VM disks are remote iSCSI disks (over shared LVM) - no local disks are attached to survive a failure/reboot of an iSCSI storage the two VM disks are attached to different iSCSI storages and are mirrored with ZFS inside the VM if I create an EFI disk on one iSCSI storage...

Hello Fiona, I would like to get rid of this warning also. My storage environment - commercial iSCSI storage connected over multipath and shared LVM works stable and quite fast the big problem is the missing snapshot functionality for VMs I'm migrating my Linux VMs to root-on-ZFS with ZFS...

Hello, after some (much) fiddling, I managed to boot a VM with two (LVM) mirrored root disks over iSCSI with both libiscsi (User_Mode_iSCSI) and kernel iSCSI. I'm using other Proxmox nodes in the cluster as LIO targets. BTW: please fix iscsi-login-negotiation-failed - I skipped the tcp_ping in...

Hello, I installed a new (virtual) PVE 8 instance and created a firewall config with the WebGUI alias a_intern -- 10.10.68.0/24 ip_set s_intern -- a_intern security group g_intern -- ACCESS tcp +s_intern 22,8006 and assigned this group to vmbr0 in a firewall rule: cat...

Hello, could you please look at this enhancement again - we would really, really need this functionality. We just dumped our central Ceph storage (not proxmox Ceph) because of performance and stability issues and switched back to DAS (direct attached storage) - NVMe SSDs and ZFS. With NVMe SSDs...

Yes - very good hint - 128k volblocksize makes a big difference ! I additionally run some fio test inside the VM - the 128k volblocksize fixes the problems on sequential IO (like the tar test above) but does not slow down random read/write tests. the VM stays responsive during the tests the...

I've already created a zvol with 4K volblocksize (8K is the default) - same results. Additionally I run the test on the proxmox host directly created a 4K zvol mkfs.xfs mounted Running the test generated 500-700 IOPs on one HDD and a load of >40 on the proxmox host - like inside the VM The...

Repeated the test some more times - the results did not change IOPs to the host raw disk VM behavior proxmox host load ZFS zvol - HDD pool 500-800 completely unresponsive > 40 ZFS zvol - SSD pool 1000-3500 responsive 10-16 ZFS raw image file - HDD pool 60-180 (with pauses) responsive...

What makes me puzzled is not HW RAID vs ZFS zvol - it's ZFS raw image (ZFS dataset hosting a raw image file) vs ZFS zvol. The difference between ZFS raw image and ZFS zvol is way too big - for the same test a zvol generates 20x to 30x the number of IOPs - this quickly fills up even a SATA SSD...
