Quick sanity check request from OMV veterans.
I currently have 3 NAS rigs running at home:
1) ReadyNAS NV+ (10 years)
2) WHS on PC w/ external 8bay SansDigital TowerRaid (5 years)
3) Brand new OMV on HP StorageWorks x510
WHS is currently my media server running Plex. WHS is EOL and deprecated. Plex no longer can be upgraded on WHS OS and it's out of sync w/ Roku Plex rendering it useless. I need to retire the WHS.
ReadyNAS is my Logitech Squeeze server for music. For now, the ReadyNAS is functioning but deemed EOL by Netgear and will no longer get updates. Leave it as is for the time being, it will serve as backup NAS.
I just built and OMV installation on the HPx510 (initially was another WHS rig someone gave me). It is a 4 bay headless box w/ 1bay as OS disk and other 3bays filled w/ 1TB configured in a RAID5 volume. Since the x510 only has 2GB RAM ZFS is out of the question.
My plan was to consolidate data onto the READYNAS and OMV-NAS until I can shutdown the WHS. I want to take the 8bay TowerRaid eSATA device off the WHS and plug it into the OMVx510.
Question(s):
I could plug the new TowerRaid into the x510 and create a new RAID5 volume over those 8 disks, but that would leave the other existing 3disk RAID5 volume in place. I don't know why I would want to do that.
I could plug the new TowerRaid into the x510 and add the 8 disks (or less) to the existing OMV RAID5 volume growing it in place.
I could move all the data off the OMV-x510, delete the existing RAID5 volume, add the new TowerRaid and create a new RAID5 volume from scratch across 11drives(+-).
At this point I only have the OMVx510 rig up and running for 2 weeks, I'm just getting used to it and not 100% confidant in it. It hasn't been battle tested yet.
Amazon has WD Red 3TB drives for $99, I plan to get a few, load some external chassis and help me move data around.
Should I keep my existing RAID5 volume or start over? I don't have enough experience w/ OMV yet to know which would be easier/safer.
Any other suggestions; wait for 3.0?, beware of Debian on external eSata?
TIA
