Topic: add 6th disk to raid 5

[dmajwool]

I have a 5-disk raid5 and I haven't found a way to add a 6th drive.

I can see the 6th drive using fdisk -l | more

and I have tried zero-ing it using dd and also copying the partition "map" from another drive in the array using sfdisk.

If I look at Manage Disk Redundancy in the console, I can see the original 5 disks are in md1 and md2, but it shows unused disks = none.

I can add the disk to the raid using mdadm -a , but it seems not to adjust the  size of the array, and I don't see any rebuilding taking place.

Is it possible?  Anyone done this?

Many thanks, David.

Hi David,

Did you ever get this to work? I want to do the same.


Thanks
