Hi,
I have done a software raid5 with 5 scci disks. Now I want to add one more disk to the current configuration without loosing data. But for some unkown reason the operation fails. Has anyone any idea why could I make this thing working ?
Thank you very much!
#raidreconf -o /etc/raidtab -n /etc/raidtab.new -m /dev/md0
Working with device /dev/md0
Parsing /etc/raidtab
Parsing /etc/raidtab.new
Your on-disk array MUST be clean first.
reconfiguration failed
This is how raidtab looks liks
#cat /etc/raidtab
raiddev /dev/md0
raid-level 5
nr-raid-disks 5
nr-spare-disks 0
persistent-superblock 1
parity-algorithm left-symmetric
chunk-size 32
device /dev/sdb1
raid-disk 0
device /dev/sdc1
raid-disk 1
device /dev/sdd1
raid-disk 2
device /dev/sde1
raid-disk 3
device /dev/sdf1
raid-disk 4
And this is how the new raidtab looks like
#cat /etc/raidtab.new
raiddev /dev/md0
raid-level 5
nr-raid-disks 6
nr-spare-disks 0
persistent-superblock 1
parity-algorithm left-symmetric
chunk-size 32
device /dev/sdb1
raid-disk 0
device /dev/sdc1
raid-disk 1
device /dev/sdd1
raid-disk 2
device /dev/sde1
raid-disk 3
device /dev/sdf1
raid-disk 4
device /dev/sdh1
raid-disk 5
