So, my port multiplier failed a week or so ago and I took the drives that were on it offline and resumed with the drives that were not on the PMP.  Anyway, I got my PMP replacement today, hooked everything back up the way it was, shut down unRAID, powered up with the new drives to bring them back online, stopped my array, assigned the disks in the exact location they used to be in, checked the restore box and started the array.  The disks were treated as new disks and began clearing.  I immediately hit the reset button but the damage is done...all three disks now show as unformatted.

 

I thought I had done this the correct way as I moved some disks around a few weeks ago and did the same thing.  Is there any way to get back any of the data on those disks?  The clearing only lasted a few seconds and I've tried some reiserfsck commands, but I'm not real sure what I'm doing. 

 

Thanks for any advice.

Good luck.

Thanks, Joe.  I started trying something that looks the same that I found in another thread here.  I'm using

 

reiserfsck --scan-whole-partition --rebuild-tree /dev/md4

 

I'm guessing it's the same thing.  This is going to take days for three drives.  I just hope it works

Just wanted to say that the first drive was as successful as I could hope for, I guess.  I haven't had the chance to really go through and rename/reconstruct the file structure, but after briefly perusing the lost+found folder, it looks like the majority of my NAS files are there.  I do have a little concern over the 100+ numbered files with no extension there were, however.  I'm hoping these were just old deleted files that it was able to come up with.  Otherwise, I have no idea what they were.

 

I started the second drive pretty much immediately afterwards and it has bad blocks, so I had to do a /sbin/badblocks -b 4096 -o badblock.lst and then add the -B badblock.lst to my reiserfsck rebuild .  It took the rest of the night to construct a bad block list and I started the recovery on it a little less than 2 hours ago.  It should complete in about 3 hours from now.  That drive has the bulk of my TV episodes...not irreplaceable, but I'd rather not lose 500GB of TV shows.  The good news is that it's a Seagate drive, so I'll be able to get a replacement under their 5-year warranty.  The third drive is a spill-over for more TV episodes.  I think it's only around 1/3 full.  Hopefully no bad blocks there.

 

I'm only putting my progress here for any other unfortunates there may be in the future.  I'd also like to say that this is scary stuff to a linux beginner, but it appears to work pretty good.

 

--Update

 

My second drive appears to be 100% recovered.  The folder structure was completely intact with, as far as I can tell, all files and the lost+found looked only to contain non-extension files that were once deleted.  I'm going to dd everything off of that drive to one of my standby spares and RMA it for the bad blocks before bringing it all back up.  I started the rebuild on the third drive and it should be done in ~5 hours.  With a little luck, I may be back in business with some TV shows at bedtime tonight...I can only hope!

 

--Update 2

 

Final drive finished and I only lost one X-Files episode and some metadata that went with that season (6).  Other than that, everything looks intact.

I have to say, that is quite impressive.  I doubt if NTFS would be as kind to you.

How did you check the validity of all your files?  I've always wondered about this.
