RN31400 increase space needed with EDA500
I would like some advice on the proper way to increase my space on an RN31400 with a EDA500. Both are fully populated with the following:
RN314 4 x 5 TB drives (13.63 TB)
EDA500 2 x 5 TB; 3 x 2T...
It is unfortunate you decided to make the EDA500 two volumes. Otherwise, you could just replace one of the 2TB's with a 5TB and gain 3TB.
I recommend you first make a backup, but the following should work:
With power off, remove one 2TB drive from the EDA, then boot. It will come up with that volume "degraded", but still accessible (assuming it's RAID5, based on our reported volume size). Now, hot-insert the new 5TB and use it to expand the current 2x5TB volume.
Then use a backup job to copy everything off the 3x2TB volume (which really only has 2 drives at this point) to the others, then destroy the smaller volume and remove the drives. Adding yet another 5TB would be the best solution for more space, but you could use the 2x2TB's for a separate volume again.
One thing to keep in mind when looking at new NASes is that they don't support the EDA500.

Note you can alternatively expand any of the volumes if you get a pair of larger size disks - though the process with FlexRaid can be a bit confusing. Performance is faster in the RN314 chassis, so I'd recommend expanding that first, and retiring the 3x2TB volume on the EDA.
But this should work, and of course it is less expensive because you are only buying one disk.

So you would need to get the number of disks to 8 or less before you upgrade the NAS - then you can directly migrate all the disks to one of the desktop NAS models.
