zfsinstalled as part of base from 13.0
my custom setup
- 4x10T disks, one pool with two mirrors
- gives ~20T usable storage
- prep disks
wipefs -a /dev/<disk> parted /dev/<disk> mklabel gpt parted /dev/<disk> mkpart "<custom id>" zfs 0% 100%
The custom id shows in ZFS, i use a location identifier as below
- 2 character server prefix,
kkforkinakuta - 2 character enclosure identifier,
e0,e1, etc. - 2 character disk positon (in my case top to bottom),
d0,d1, etc. - serial number of the physical disk, taken from the label
For example
root@kinakuta:~# zpool status ~
pool: crypt.kk
