    zfs_arc_max does not seem to work

    Very old thread, but the problem occurs when you have root on zfs, requires running update-initramfs -u -k all and reboot

    [SOLVED] Where do I set below threshold?

    I think "SOLVED" is not really the correct term for this thread.

    Vm based log

    You might find more information in /var/log/syslog of the node the VM is running on.

    VMs freezing and unreachable when backup server is slow

    I'm assuming you mean vzdump --bwlimit ?

    Restore individual disk from PBS

    I noticed proxmox-backup-client snapshot list shows image names without the .fidx bit, so i needed to add that.

    VMs freezing and unreachable when backup server is slow

    Running a remote PBS for several clusters i'm getting the impression these problems became quite rare after improving disk IO/zfs performance on the PBS. Network speed seems less relevant.

    [SOLVED] How to remove Cache Device from ZFS Pool

    You should be able to just remove cache devices. If that makes the server hang it would probably be a hardware problem. Or maybe it was a bug that's long gone now.

    In /etc/ksmtuned.conf increase KSM_THRES_COEF and then systemctl reload ksmtuned

    [SOLVED] No local-lvm after Join Cluster/proxmox ve 5.4-3

    I ran into this when a second node that had no local-lvm ( zfs only) was added. Adding this to storage.cfg on pve1 fixed it: lvmthin: local-lvm thinpool data vgname pve content rootdir,images nodes pve1

    Make ISCSI usage simpler

    Management is expecting them to help out, and Truenas/ixsystems support seems to have no problem with LVM over iSCSI, they suggested that. I'd be happier with ZFS over iSCSI but that'd mean patching all nodes. And me being the only rocket surgeon in town.

    Make ISCSI usage simpler

    Sadly that won't work with Truenas Core. There's a patch called Grandwazoo but Truenas support says they don't cover that.

    Shared LVM on iSCSI: how safe is it?

    Note: this does not mean you can't thin provision storage for your VMs. Discard will work.

    Ah thanks, that was indeed wrong URL, fixed it.

    Make ISCSI usage simpler

    Keep in mind you can't use LVM thin/snapshots that way. See Shared LVM on iSCSI: how safe is it?. The good news is that the data on storage/target side will be sparse.
