Hello

After a disk failure, the hot-relocation splitted a subdisk of a stripped and
mirrored volume into two subdisks with different sizes on two different physical
disks.

 failed disk                  

How can I move the two subdisks F-09 and G-10 back to the original subdisk A-01
after replacing the failed disk? I like to have the original layout.

How can I do it with the commandline command.
How can I do it with the graphical interface "vxva".

Thanks

Conti
