Listmates,
I have a quandary. I had two Seagate 750G drives in a software raid on machine A. I needed to remove one of the drives and RMA it due to excessive read/write head schizophrenia. I now have the device out of the box to RMA but I need to mount it to delete some of the data. I tried mounting is via usb, but received an error due to raid as the file type:
[23:03 alchemy:/home/david/linux/packages/SRPMS] # mount /dev/sdb1 /mnt/750 mount: unknown filesystem type 'linux_raid_member'
So next I decided to create a temporary md0 on my laptop and add one drive to the array. No dice:
[23:06 alchemy:/home/david/linux/packages/SRPMS] # mdadm --create /dev/md0 --level=1 --raid-devices=2 /dev/sdb1 /dev/sdc1 mdadm: /dev/sdb1 appears to contain an ext2fs file system size=732571864K mtime=Fri Apr 3 20:21:45 2009 mdadm: /dev/sdb1 appears to be part of a raid array: level=raid1 devices=2 ctime=Fri Mar 27 15:38:36 2009 mdadm: Cannot open /dev/sdc1: No such file or directory mdadm: create aborted
"frickuth!"
OK maybe:
[23:03 alchemy:/home/david/linux/packages/SRPMS] # mdadm --create /dev/md0 --level=1 --raid-devices=1 /dev/sdb1 mdadm: '1' is an unusual number of drives for an array, so it is probably a mistake. If you really mean it you will need to specify --force before setting the number of drives.
Again no joy!
Well, how to skin this cat, there must be an easy way, but obviously I'm struggling with it. What say the RAID gurus?
Nevermind -- Just read stupid! It wasn't a mistake to just like it said "If you really mean it you will need to specify --force before setting the number of drives." Worked like a charm! I had the drive plugged in the USB port. As soon as I issued: mdadm --create /dev/md0 --level=1 --force --raid-devices=1 /dev/sdb1 That familiar "Open in a Separate Window" dialog appeared and after saying yes, my "sound of one hand clapping" array happily appeared in the window. -- David C.
