Creating containers fails when I try to use my "tank" pool but succeeds when I use my "storage" pool.
These commands are just for easy illustration and error messages. I get the same messages clicking buttons on the gui.
failure using the "tank" zfs pool:
success using the "storage" zfs pool:
A dataset does not get created on the "tank" pool.
I can create volumes on the "tank" pool manually just fine.
Proxmox is new to me and I haven't done much with zfs in a while. This is a test box I'm using to kind of validate some design ideas for an all-in-one that uses zol instead of passthrough to freenas or similar. I installed from debian so that I could setup luks. Root is lvm on luks on mdraid1 ssds. "tank" would be a zfs mirror of luks partitions off of the ssds to host VMs. "storage" would be mirrors of luks partitions on spinners mainly for media.
My google skills are letting me down here. Any hints?
