Hi,
I've a problem wit my software raid.
After replacing one drive with a bigger drive another drive in the raid
raises an error:
lost page write due to I/O error on dm-1
After rebooting I can -re-add the drive into the array but after 30 minutes
the raid stops with the same error.
Now, I don't know what is to do !?
I can't modify the raid nor can start it.
FileServer:~# mdadm -A -s
mdadm: /dev/md2 assembled from 2 drives and 1 spare - not enough to start the
array.
FileServer:~# mdadm /dev/md2 -r /dev/sde1 -a /dev/sde1
mdadm: cannot get array info for /dev/md2
FileServer:~# mdadm /dev/md2 -a /dev/sdd1
mdadm: cannot get array info for /dev/md2
FileServer:~# mdadm --examine /dev/sdc1
