not sure if I am posting the right section, it looked appropriate here.
Hi there,
I have been using xpenology on this box for the last 4 years, currently running DSM 5.2 (i know, upgrade to DSM 6 was planned this month).
My setup is : 4 bays with 4TB drives, CD-ROM port 6TB and E-SATA with 6TB drive set-up in SHR.
Everything was working perfectly until I got a Smart quick scan failed issue on drive 5 (CD-ROM port), I ordered a new drive(waiting for it) but after a reboot yesterday and I got Volume Crashed.
Which weird because I know that 5 out of the 6 drives are working. I can still see the 6 drives in the BIOS.
Before I receive my new drive, I would like to perform the steps needed to ensure that:
-disk 5 is indeed working but was just somehow disabled
-I can remount volume1 (in a degraded state) and wait until I receive my new drive to rebuild the array
I am not sure which info I should share with you, but your help would be much appreciated, I have backups of the important data but the amount of data on this volume means there are a lot of other things that it would be nice to access. I have ssh access to the box so can provide additional info if needed.
space history xml from a time when everything was working is as follow:

Thanks so much for taking the time to read this, your help is REALLY appreciated, I am worried I will break the whole thing and lose a lot of historical data.
