ZFS

Here are some helpful commands for managing ZFS and ZPool on Ubuntu

VDEV

Useful for populating /etc/zfs/vdev_id.conf:

printDisks() {
    for i in /dev/sd[b-i]; do
        fdisk -l $i
        echo "\n"$(for j in `seq 1 45`; do printf ' - '; done)"\n"
    done 2>&1 | less -p "Disk /.*$"
}

Perhaps it is better just to take a look at the drives by id though:

ls -lAh /dev/disk/by-id

After making the vdev_id.conf file, run:

sudo udevadm trigger

Commands for creating zpool

zfs create -o quota=5TB -o sharesmb=on -o mountpoint=/mnt/zeus olympus/zeus
zfs create -o sharesmb=on -o mountpoint=/mnt/zeus -o casesensitivity=sensitive -o nbmand=off olympus/zeus
zfs set sharesmb=on olympus/zeus
zfs set mountpoint=/mnt/zeus olympus/zeus
