my OMV installation WAS 3.0.7x. It was not remotely answering from a couple of weeks and I could not phisically access it until this evening.
It is a 2 parts hardware setup: one part is an HP316M1 with IBM1015 controller on it, the other part a case with 24 3,5" bays and HP sas expander, apower supply and a PCI module to power to the HP expander.
Two raid groups were on it:
RAID6 both !
Switching the NAS on a smell of burned electronic raised from the HP316M1 and soon it switched off.
From the 24 Bays case a continuos clicking was coming up from one or two drives.
Ok, you are right, it is an horror story.
Now I need to try to rebuild and recovery everything.
I need some advice from the experts:
Once I move the IBM card to another PC and connect it back to the 24Bays case, I need to discover what happened to the drives and eventually which have failed and recover sanity before trying to reinstall OMV. I need to do this in the safe possible way.
Which tools do I need ? Which shell commands ? Which distribution/iso ?
Any warning ? It is really an huge setup and I want to recover everything or as much as possible.
Also I don't want any tool to start rebuilding the drives automatically but only if I manually start the process.
Any help is highly appreciated !
