ZFS
This section is about the Z File System
Reference URL
When we create vdev and zpools, we should always reference the unique identifier of the disk or partition. This is because device names are dynamically created during the boot sequence depending on which devices are available. So, if a particular disk such as sda is not useable, what was sdb
will replace sda
.
Commands
Always use the unique ID of the disk when creating a zpool as shown below.
FreeBSD sudo zpool create -f -m /zstore/x250pool -o compatibility=ubuntu-22.04 x250pool raidz1 ada1p1 diskid/DISK-W624R9ERp1 diskid/DISK-W624R9ERp2
To find out the unique partition labels:
Linux lsblk -o NAME,PARTUUID,PATH,FSTYPE,LABEL,UUID,PARTTYPENAME,PARTLABEL,PARTUUID
To set a label for the partition:
Linux e2label
/dev/sdb1 “My Label”
