Hi team,
During a new PE install I decided to try out ZFS with RAID 10 across my 4 disks.
During install I selected ZFS and all 4 disks, and install completed and server rebooted. Everything seemed to work, great!
However, after playing around with zfs list/status and zpool list/status my OCD came to surface.. as the 4 disks are not partioned identically.
Shows that sda and sdb is mirroring between partitions and sdc and sdd is mirroring whole disks.
I noticed that sda and sdb have also got 2 boot partions. sdc and sdd has not.
Now questions:
1) Is this expected? Or should I recreate the mirror and/or reinstall PE?
In real life it should be enough with the boot partitions on sda+sdb as if I loose both drives, I would loose my mirror+data anyway
2) Would it be better to shrink the rpool and have several zpools? This is just a test/dev server, so no big deal... just curious if there would be something special to consider.
