Okay, so my RAID5 array went out last night. Woke up this morning to this and went to check everything. No power failures, no SMART errors and drives in the array seem to be fine.
No new data written to the disks at all. This is all mostly non-important data, but it is about 7TB of data so I would like to recover it if I can
All the important data has been backed up so there is no concern there.
Specs on the array.
4 3TB seagate drives (no hot-spare) in RAID5
The event log showed that the 2nd and 3rd drive in the array were failed. That is what made me suspect some random error and not a true drive failure.
In the process of rebuilding the array now to see if everything is okay. If not, then it is time to play around with R-studio. I have not done any of the rescue commands and the disks are all in the correct order. I have all the correct information about drive order and array parameters.
I guess the questions are, what is the best way to go about doing everything correctly with R-studio? I have three extra 3TB disks that I can use, since there are 4 drives in this array do I need to pickup another 3TB disk to make a perfect image for R-studio?
Thanks in advance for any help.
UPDATE: Rebuild stalled at around 68%. Device log shows multiple reading errors on one of the drives in the array. I guess it is time for R-Studio. Need some tips from here on out as I am completely new to R-Studio.
