raid 5 catastrophy

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



I made a mistake on a raid 5 array.  I accidentally
tried to ?raidhotadd? 2 of the 3 drives from the raid
5 array into another array.  Now the two partitions
FROM the raid 5 think they are part of the other
array.  The raidtab for the array is:

raiddev			/dev/md4
raid-level		5
nr-raid-disks		3
chuck-size		64k
oersustebt-superblock	1
nr-spare-disks		0
device			/dev/hda2
raid-disk		0
device			/dev/hdb2
raid-disk		1
device			/dev/hdc2
raid-disk		2

Ultimately, the raid5 array is broken.  It won't start
because it only has one good disk to its name right
now.  How can I fix this?  I assume the data on the
other two drives is still intact (bad assumption?)

Thanks for the help!
