I have a broken raid1 drive set - i was able to fix 1 but the other raid
still has issues.
i have gone through the tutorials online to bring it back online but still
unable to bring it back.
Do i have to run fsck on the individual member drives ???
my /proc/mdstat looks like:
Personalities : [raid1]
md1 : active raid1 sdc1[0] sdd1[1](S)
976758841 blocks super 1.2 [2/1] [U_]
md0 : active raid1 sda1[2] sdb1[1]
972654456 blocks super 1.2 [2/1] [_U]
[==========>..........] recovery = 50.7% (493690944/972654456)
finish=416.5min speed=19162K/sec
my fstab is :
# <file system> <mount point> <type> <options> <dump> <pass>
proc /proc proc defaults 0 0
# / was on /dev/md0 during installation
UUID=611258bc-4ace-4779-b44d-73ba1949f7db / ext4
errors=remount-ro 0 1
# swap was on /dev/md1 during installation

/dev/fd0 /media/floppy0 auto rw,user,noauto 0 0
/dev/md1 /mnt/raid ext4 rw 0 1
my questions is :
1. how can i bring it back online.
2. what is the (S) mean ?
3. how do i run fsck or other utility on ext4 filesystem ?
4. do i run it on the raid1 device /dev/md0 or on the individual devices
/dev/sda and /devsdb
thanks
