Been working towards growing my file system by replacing my current 2TB drives with 3TB drives. My setup is 4x2TB drives in RAID10 (2 mirror: /dev/md1 and /dev/md2, striped together for /dev/md3) managed by OMV 4.1.22-1. I wiped each 3TB drive, then replaced one at a time and recovered md1 and md2 with the new drives. Both show up clean, with the same space. I couldn't grow the mirrored arrays via the gui, so I ran "mdadm --grow /dev/md1 --size=max" for each mirror, and now they show the newer size of 2.73TB each, in a clean state. Data still in tact, working fine. The striped array md3 isn't reflecting the larger size. I'm not even sure this is possible at this point as I just found this page stating that RAID10 isn't growable. Hope I didn't just back myself into a corner. Any way to get this working?
Another thought is I go back to the 4x2TB setup with the RAID10, how I had it, and use 2 of the 3TB for a RAID1 array and move my shows over to that. I'd like to not lose the >3TB of data in the process if possible. Now I'm not even sure I can shrink md1 and md2 to go back to the 2TB drives. Any help is appreciated!
