Thread: degraded raid

i getting message systems raid has problem @ startup. although when go ahead , start degraded raid cannot find degraded. has happened before can see raid in degraded condition upon boot.

code:

where else can more information? logs?

maybe definition in /etc/mdadm/mdadm.conf isn't right. fix or leave it, run

code:

update-initramfs -u

send config bootloader stuff. (maybe 1 isn't proper.)

logs check /var/log/kern.log
