I have a simple wee TS210 QNAP which was set up to mirror the discs. I had error messages consistently appearing on drive 2 (file systems is not clean etc etc.....) so bought a replacement drive. Basically I did this:-

Removed the 2 drives, put the new hard disc on drive 1, moving what was drive 1 on to drive 2.
Formatted the new drive on drive 1, the did firmware update, took the opportunity to run a disc scan too on the existing disc. All fine and dandy

So all data still present on drive 2 (just music, films and photos), accessible and working OK, the new drive 1 is formatted, ready but empty.

Then I logged in to NAS operating system > system settings > storage manager > raid management.

Select disc 2 > migrate > then selected disc 1 as the destination, showing disc2 mirrored disc as the source. This theoretically should copy the contents of disc 2 over to disc 1 and we return to the previous operating state ie RAID1, mirrored.

Nothing....... nada. What am I doing wrong? Can I assume the TS210 only allows migration in one direction ie disc 1 to disc 2 or is there something more fundamentally wrong I am doing? also the hard discs are not the same brand, but the same spec - the previous ones were Seagate Barracuda, the new one is a Toshiba but presumably this shouldn't be an issue.

Can anybody assist?

I think you are expected to replace the faulty drive and then let it get on with automatically.

Thank you. SO if I swap the drives around, all should be well?

I kept the one that came out the machine too - going to reformat it and use for backups only I think

I would just move the good one to its old slot and then check the GUI looks ok. The new drive doesn't need formatting or anything as the NAS will sort it. Insert new drive if all looks well.

I presume you have a backup.

I'd suggest you open a support call with Qnap (via their website) prior to doing anything (unless you're confident youve got a good backup and know what you're doing).

The support guys are actually very good and will remotely dial in (via webex or teamviewer) to get a current status of your box, prior to making recommendations.

I was in a similar situation to yourself (failed drive) and tried swapping drives etc. In the end I needed a Qnap engineer to dial into the box and manually mount the filesystem (via the CLI).

I'll switch the old HDD back to its original slot and see how it goes. All files and folders still seem to be there, which is just as well as I don't have a backup......... Yet.

OK folks

Have now put HDD 1 back in its original position with the new disc in slot 2. No difference. Files still visible and usable on the original disc. Red status light flashing on the front of the NAS with the HDD1 and HDD2 on constantly. Logging in to the QNAP utility shows nothing happenning in the background. Stumped.....

There are probably fixes that QNAP can apply. I suspect it's the earlier attempt at a migration. Since you can't afford for it to go wrong you should open the ticket as the other guy suggested. They can TV on and run diagnostics are some command line magic.

I have got one of these and had a disk failure in it...

First up, grab a complete copy of your data as a back up on to a different disk. USB is quickest but a 1TB drive will take a good few hours to copy across compared with over a day over the network.

Once that is completed (and you have checked that all your stuff is present and correct), then I put the good old HDD in slot 1 and the new HDD in to slot 2. I then formatted the drive and told the unit to get on with rebuilding the mirror.

This also takes a few hours and the warning light will continue to flash whilst it happens. You can check that the new disk 2 is accessible by turning the mirroring off and checking if you can see the drive.

Good luck!

In the case of RAID failure you wouldn't normally want to start swapping the remaining good disk(s) around. I am not sure what benefit you would hope to achieve by doing that.

Different brand drives may have slightly different geometry that means that they have a few less usable Mb or Gb. The new drive might be a tiny fraction smaller and thus unable to be used to rebuild the RAID. I expect there should be a screen somewhere in the GUI to show drive stats.

Dont know what this means, but the warning that cropped up prompting me to change the HDD over was:-

5 Reallocated_Sector_Ct / Value 097 / worst value 097 / Threshold 036 / worst value 140

Other than that it's working fine........ Still not copying over though......

Yes - changing that disk is the right thing to do. AIUI Rising reallocated sector count is an early sign of failure.

Have you started copying your data off the box yet?

No. I can't alas......

EDIT - the new disc is slightly larger than the original. 1.854tb against 1.832tb

Having a larger drive is fine.

I know that now......

May change tactic. I may put the NAS back to hoe it was, the new disc in the casing then back up to the new disc. Then reformat the NAS and restore from the backup,

Feasible?

I'm really not sure what you mean.

Is there some reason to not involve QNAP support?

Are you happy to SSH on and run some commands in an attempt to diagnose it? You could get more idea of the current state of the system.

Why is RAID pointless on a home system?

Do tell...

Have contacted QNAP support. Not home until Wednesday now though so nothing doing until then.

What do you mean by SSH?

What I meant was restore the QNAP to its original state with the original drives, back up to the new drive I bought then reformat the QNAP and restore from the backup

Yes, do tell..

RAID1 protects against a single disk failure for the sake of £70 for a disk - if the OP's disk had failed completely then he would still have his data = result.
