Moving drives from qnap 2 qnap - How would you do it ?

Post by spikemixture »

I have 2x qnap with 8 HD each
Lets call then X and Z

Z has 8x8TB drives (Raid 5)
Y has 8x10TB drives.(Raid 6)

Both have QTS on SSD's with the HDD DATA only

I wish to swap all the drives so Z has the 10tb and Y has the 8TB.

Z is my main server and backs up all my data to Y.
I have another backup (X) so loosing Z+Y data is not an issue if all goes south.

Is stopping Y and taking 1 drive at a time and putting in Z and letting each rebuild the way to go ?
I realize this will take days !

When all the 10tb are in place I will start from scratch and rebuild Y with the 8x8TB!

you should be able to shut down both nas ..swap the disks and start them up (if migration compatible)

no raid rebuild needed

That sounds scary!

How do I check "if migration compatible"
Ok checked my 2 NAS are ok.

But I only want to swap the HDD not the SSD!!

So with X, Y and Z, there are 3 NASes, not 2? According to your description, if you put the 10TB drives into Z and the 8TB in Y, then X has no drives at the end? But then you say you'll rebuild X with the 8x8TB. This doesn't make much sense.

It would help if you told exactly what X, Y and Z are, which ones are backed up, and where they are backed up, and where their HDs are going?

The way I'd do it if possible is destroy and rebuild the whole arrays at once and restore from backup. I'd also ask QNAP support for advice - there may be a way to do a "pseudo-migration" of the whole arrays requiring some minimal reconfiguration of the host or worst case, complete reconfiguration from scratch, while preserving all data (including on the SSDs that are not moving, except reinstalling apps and such).

Sorry yes the XY & Z was wrong - fixed now
I want the 10TB drives from Y to replace the 8TB drives in Z.
X is a Synology nas that had the 2nd backup and not in the 'swap'

Still don't get it...

Lets call then X and Z

Z has 8x8TB drives (Raid 5)
X has 8x10TB drives.(Raid 6)
Per your signature, X with 8x10TB is 'Qnap TVS-1282 i7' not Synology.

I don't know how to explain it any better.

Y is the Qnap 1282 with 8 x 10TB
Z is the qnap 1277 with 8x 8TB
X is the Synology and has nothing to do with this question - other than it another back up of the media on Z (and Y)

I want the 10TB in Z (1277) and the 8TB in Y (1282)

Does that make sense ?

Yes it does now. But that's not what your first post is currently saying. You may want to re-read it twice or thrice to see what I mean. I even quoted the part that is contradicting the rest but apparently you didn't catch that.

I already responded earlier in the thread.

It seems to me it would be quicker and put less strain on the disks to build a new array from scratch in the 1277 using all the 10TB drives from the 1282 at once, and restore the 1277 data from backup to the new array, rather than to expand the existing 1277 array one 10TB disk at a time. Assuming you have a full backup and can restore it at maximum array throughput. You can take this opportunity to build a RAID 6 array in the 1277 with the 10TB drives instead of a RAID 5 if you so wanted. The downside is that the 1277 will be unavailable during this operation. The upside is that the 1282 would be back up and running with the 8 TB drives much sooner than it would have been otherwise.

You can't do a direct migration like @dolbyman suggested (shut down both units, swap disks, start up both units - done) since you won't be moving the SSDs (which contain the system volume I guess). But there may be a way to swap a whole array from one unit to another with some manual command line reconfiguration tricks that only QNAP knows how to perform. Which is why I also suggested to ask QNAP for advice in case such a way exists and they'd be willing to help. Both units are migration-compatible.
