I'm running an Ubuntu Linux NAS server with 4 2TB drives in software RAID 10.
I created the array during installation (with Ubuntu Server disc), but the layout is
near and the chunk size is
I want to change the chunk size to
256 and the layout to
far. How do I do this?
Here's the output of mdstat:
root@server:~# cat /proc/mdstat Personalities : [linear] [multipath] [raid0] [raid1] [raid6] [raid5] [raid4] [raid10] md0 : active raid10 sde1 sdd1 sdc1 sdb1 3907026816 blocks 64K chunks 2 near-copies [4/4] [UUUU]
I would prefer to make the change non-destructively to save time copying the data over again, but the data is backed up, so destructive changes would be ok too.
Thank you for any help.
