Hello
I have been using OpenMediaVault since the start of the project (and Volker's FreeNAS, for years before).
I have OMV (v1.11) on an HP uServer (N40L).
I upgraded from a single 3TB disk to 2x3TB disks configured as RAID1 (/sdb + /sdc as /md127).
I have just added a new 3TB disk (/sdd) to increase capacity. I am having problems migrating from the 3TB RAID1 to what I understood would be a new 6TB array (RAID5?)
After installing the new drive, I used the webGUI to add the device under 'RAID Management'. After several hours of re-building a degraded array, the output of 'mdadm --detail /dev/md127', is:
ZitatAlles anzeigen/dev/md127:

I thought I next had to grow the RAID using something like 'mdadm --grow --raid-devices=3 /dev/md127'.
I was not clear if command 'resize2fs' was then needed.
However, the output of these commands is:
Zitatroot@OMV1:~# mdadm --grow --raid-devices=3 /dev/md127
mdadm: /dev/md127: no change requested
root@OMV1:~# resize2fs /dev/md127
resize2fs 1.42.5 (29-Jul-2012)
The filesystem is already 732566356 blocks long. Nothing to do!
I have read several posts on this forum (and Adding storage drives and changing RAID setup to suit), but I don't know if the only method is to degrade the array.
I have my data in a back-up, and so if it is easier, I can simply delete the 3TB RAID1 array, and rebuild a new 6TB RAID (I assume RAID5 is most appropriate?)
However, I thought it would be possible to migrate the array.
I would really appreciate any help with this...

Andy
