I need to upgrade from 12.04 to 16.04; I am currently sitting on a degraded RAID1 array (one disk failed):
~$ cat /proc/mdstat
Personalities : [linear] [multipath] [raid0] [raid1] [raid6] [raid5] [raid4] [raid10]
md1 : active raid1 sdb6[1]
40381312 blocks super 1.2 [2/1] [_U]
md3 : active raid1 sdb7[1]
41028480 blocks super 1.2 [2/1] [_U]
md2 : active raid1 sdb9[1]
2638384960 blocks super 1.2 [2/1] [_U]
md0 : active raid1 sdb5[1]
210039616 blocks super 1.2 [2/1] [_U]
unused devices: <none>
my questions:
. will the upgrade handle RAID1? I have read that only the server installation supports RAID for 16.04; I currently have a desktop installation.
. if not, do I have to revert to non-RAID disks before upgrading?
. if yes, does the degraded array pose additional problems when upgrading? i.e. had I better rebuild before or after upgrading?)
. also: is it perhaps advisable to upgrade first to 14.04, then to 16.04
Any advice much appreciated
