Hi everyone,
Is it possible to add drives to an active RAID-10 array, using the "grow"
switch with mdadm, just like it is possible with a RAID-5 array? Or perhaps
there is another way?
I have been looking for this information for a long time but have been
unable to find it anywhere. The man page for mdadm does not mention RAID-10
at all so that didn't help either. Has anyone tried it?
The man page for mdadm does not mention it because it is not
supported.
There are several reshape options that I would like to implement
including
- raid5 -> raid6
- shrinking raid4/5/6
- raid0 -> raid5
- changing chunksize/layout of raid4/5/6
- raid10 growing and layout change
While changing chunk size is probably the least generally useful, I sure
would like to have it ;-)
