Corrupt root with new disk - case ref. no. 166 876 51
I had an error message from my ReadyNAS Duo saying that a bad disk was detected. I was still able to access all of my files - I have two disks in there in a RAID setup. Luckily, I had just bought a...
Thanks mdgm.
I contacted support and must say that the support experience was (eventually) great despite my software support having expired months ago.
Initially, I was told that I would have to do a factory reset because I had used a HDD not on the compatibility list.
Not happy with that, I then called back to see if it was safe to try to reinstall that disk i.e. go back to the same disks in the same channels as before, and was told that should work. However, with both disks in, I still had the same problem.
Eventually, I got through to someone who was very helpful, and the steps which resolved this are:
1. With ReadyNAS switched off, pull out the second disk, so it only had the disk which I pulled out.
2. Switch ReadyNAS on to see if it started correctly - it did.
3. Hot-add the disk 2
4. Resync
If anyone does try this in the future, it is a good idea to take an image of the disk which was pulled and which you know has no data integrity, in case adding the second disk causes a malfunction.
Gotta say, I am one relieved man...!
:D
As a final test, once the resync has completed (it still has over an hour to go), I will power the device down, and try to start it with just Disk 2 inserted - if the resync has been successful and it is a perfect mirror of disk 1, it should start up as normal...I'll let you know how it goes.
