    Did you find an answer? I also wonder. dnode_size keeps increasing, doesn't matter what is the zfs_arc_dnode_limit_percent I set. I've been tracking dnod_size while doing a dump of a 120+ GB of size, and I can see it keeps increasing and end above the limit set. Update: by tracking minute by...

    [SOLVED] Backup causes ZFS: arc_reclaim/arc_prune to nearly freeze system

    Would you be able to advise on what % of your total memory size you had to increase zfs_arc_max? As per wiki https://pve.proxmox.com/wiki/ZFS_on_Linux, it says "allocate at least 2 GiB Base + 1 GiB/TiB-Storage". Which is what I've 3GB for 1TB of storage, but I still face this issue, even after...

    ZFS uses RAM equal to files being written to it

    Shouldn't this parameter be set @proxmox install when the root system is on ZFS -> meaning that the install wizard should ask the user for this parameter? Just a thought as this can be ignored by many admin and lead to stability issue.

    Adding a second IP to a LXC Container

    Just to mention that this works perfectly with failover IP @ online.net as well. THANKS You just need to make sure that the same MAC address is being used for any failover IP that should be used by the container, and that the MAC address of eth0 on the container is also set to the same MAC address.
