I have a raid 5 with 4 scsi disks.
This raid was on other server and I would like to mount it on a new server without lost dat, if it is possible
Before it was configured as:
-----------------/etc/raidtab--------------------
raiddev /dev/md0
raid-level 5
nr-raid-disks 4
nr-spare-disks 0
persistent-superblock 1
chunk-size 4
device /dev/sda1
raid-disk 0
device /dev/sdb1
raid-disk 1
device /dev/sdc1
raid-disk 2
device /dev/sdd1
raid-disk 3
------------------------------------------------
Now, I make another /etc/raidtab on the new server as:
-----------------/etc/raidtab--------------------
raiddev /dev/md1
raid-level 5
nr-raid-disks 4
nr-spare-disks 0
persistent-superblock 1
chunk-size 4
device /dev/sda1
raid-disk 0
device /dev/sdb1
raid-disk 1
device /dev/sdc1
raid-disk 2
device /dev/sdd1
raid-disk 3
------------------------------------------------
but it can't start.
I have tested the disks with --> mdadm -E /dev/sda1 , mdadm -E /dev/sdb1, mdadm -E /dev/sdc1, mdadm -E /dev/sdd1 and all the results are ok
I think the problem is that I use /dev/md1 instead of /dev/md0, but for several reasons I can't use /dev/md0 to do it.
Then, are there any solution to mount this raid without lost data?
Thanks in advance
