I hope this is the right place to ask this question. I have at 8
drive RAID 6 array that I wanted to grow to 13 drives (adding 5 more).
I issued the mdadm command and checked /proc/mdstat and all looked
well. However at some point in time a disk failed and that hung my
system. Upon reboot the array is inactive and I can't get it to
reassemble.
/proc/mdstat shows this
md1 : inactive sdp1[11](S) sdi1[3](S) sdd1[7](S) sdr1[13](S)
sdg1[1](S) sdc1[6](S) sdq1[12](S) sdn1[9](S) sdo1[10](S) sdh1[2](S)
sda1[4](S) sdf1[0](S) sdb1[8](S)
25395674609 blocks super 1.2
If I look at mdadm -E /dev/sdX1 I see most are State active, while
some are State clean.
