I change one bed disk for my ex4 raid5
and it show degrade every time when reboot, and will not auto rebuild
I try use command “mdadm -add /dev/md1 /dev/sdd2” to fix this probleam
then raid rebuild finish,
but when I shutdown and reboot, EX4, it became degrade again!
NOTICE: shutdown and reboot, if reboot directly, it wil be fine, but shutdown and reboot, it will degrade!
I search from on web, It shows a bug in mdadm, but already fixed in new version, doe’s WD EX4 use the version have bug?
