mdadm with liquorix
I'm trying out the Liquorix kernel 3.18-9.dmz.1-liquorix-amd64. I can't use my RAID0 array with it.
When using the Debian kernel:
Code:
# mdadm -v --detail --scan
ARRAY /dev/md/9000 level=raid0 num-devices=3 metadata=1.0 name=siduxion:9000 UUID=ee616026:23395ae0:be52872d:fd9a597f
devices=/dev/sdb1,/dev/sdc1,/dev/sdd1
# cat /proc/mdstat
Personalities : [raid0]
md9000 : active raid0 sdb1[1] sdd1[2] sdc1[0]
5860536832 blocks super 1.0 512k chunks
unused devices: <none>
This is the error I get when trying to assemble it under the liquorix kernel:
Code:
# mdadm -v --assemble --scan
mdadm: looking for devices for /dev/md/9000
mdadm: no RAID superblock on /dev/dm-0
mdadm: no RAID superblock on /dev/sdj2
mdadm: no RAID superblock on /dev/sdj1
mdadm: no RAID superblock on /dev/sdj
mdadm: no RAID superblock on /dev/sde1

mdadm: no RAID superblock on /dev/sda1
mdadm: no RAID superblock on /dev/sda
mdadm: no RAID superblock on /dev/sdc
mdadm: unexpected failure opening /dev/md9000
Edit: It looks like maybe mdadm is only seeing /dev/sd[bcd] instead of /dev/sd[bcd]1
Code:
# mdadm --examine /dev/sd[bcd]1
