Hello OMV-Forum,
I have setup a fully encrypted OMV installation using this OMV wiki as well as this OMV thread.
Used version is OMV 3.0.59 (Erasmus).
Basically the RAID5 setup is (as I understand)
ext4 on /dev/mapper/abc
LUKS on /dev/mdxxx creates /dev/mapper/abc
RAID (mdadm) creates /dev/mdxxx
Currently the RAID5 is comprised of 4x 4TB HDDs (/, /boot, swap, etc. are stored on a separate SLC-USB-Stick).
I want to extend the RAID5 with another 2x 4TB HDDs, so it will be a total of 6x 4TB in the end.
Which would be the steps to be taken to add the two new drives to the RAID ?
I am no expert on this, but I guess I would need to
- add the HDDs to the RAID (mdadm)
- no changes should be necessary for the LUKS since it operates on the /dev/mdxxx ?
- extend the ext4 to the full size of the RAID
Could somebody tell me which steps to take (either in the webif or in the CLI) ?
Also should I add both HDDs at once or add one and then when its finished add the second one the same way ?
Thank you very much in advance!
