Remember I had a disk fail a couple of weeks back - and being a normal person and not a business I don't have hot spares lying about...
Well, it got back from RMA today.
And before I could plug it in, another drive got a bad block reallocation error.
So my RAID5 has 2 dead drives and is toasted :(
I had a few smaller disks on another machine which I lvm'ed together to do a backup - but I could only fit about a quarter of my data there. I'd *really* like not to have lost all this stuff.
However I do now have a 'good' drive.
Can I dd the newly dead drive (bear in mind it probably only has a bad block or two) onto the new drive and come back up in degraded mode?
Any other suggestions.
Then RMA *this* Maxtor and hope to resync in a couple of weeks (well, actually - these drives seem so damned unreliable I guess I'm going to *have* to buy a spare)
FYI these are 250Gb Maxtor SATA disks.
