QNAP failed, need to move disk

Post by ithrbruce »

Hi,

My QNAP TS-453U-RP failed and will not reboot. I have another one, a TS-421U. I would like to place the disk from the failed QNAP into the live one to recover the data. Is it possible to do that and if so how?

The live QNAP's four bays are full, with two sets of RAID 1 disks. I would like to remove the disk from bay 4 and place the drive from the failed QNAP in there. Before I do that, can I break the mirror, and would that leave the data on the disks in bays 3 and 4 intact?

And then, if I place the disk from the failed QNAP into bay 4, will it pick it up and see the data or do I have do anything else to bring it online?

Thank you.

just keep a proper backup. raid is not a backup
https://www.reddit.com/r/qnap/comments/ ... _a_backup/

so if it failed reboot, then just replace the bad drive, rebuild raid (if it can't rebuild, then start from new), or if there other issues why it can't boot, figure that out whether it requires a fix or a nas replacement, then recover from backup to the new nas or existing nas once you solved the issue.

don't count on raid to save you from things like this :/ the idea of a backup is that it's already available, no mcgyver solutions required. you just recover once it has a place to recover to. or if your backup is the secondary nas, you can just simply use that, until your other nas issues get resolved at some point (this is what i do when my main nas is down for some reason that requires a overhaul or something but i still need to access my stuff, which is convenient mirrored on my backup nas :) )

for a 4bay nas i'm not sure why you are using 2 raid 1's for your hard drives. why not 4 hdds into a single raid5? :' You can figure out if doing 2 raid1 2hdds each is better than 1 single raid5 4 hdds, there is a calculator here

oo qnap now has their own raid calculator

you cannot put cat2 disks in a cat1 device..will probably end up in complete loss of data (the old NAS model will delete the drives)

buy a new NAS(see migration guide) and have backups in the future

Hi,

Thank you both for your kind replies. My issue is not the RAID itself, I had to build the second NAS in that config due to the disks I could source at the time.

I just need to break the mirror for the RAID 1 drives in bays 3 and 4, remove the disk in bay 4, and then place the disk from the failed NAS into bay 4 and read it. Seems though that I can't?

Thank you.

Okay thanks. I am unable to obtain a new NAS. So it looks like I won't be able to read that data. Okay thanks, your help and time is appreciated. Fortunately, the data wasn't essential, it would have helped to have been able to read it but it now doesn't look like I need to. Also, I now have other backup options going forward. So all is cool. Cheers.
