Trying to rebuild lost Raid5 on Thecus
I have lost a raid 5 in a 4200PRO and now I am desparatly trying to revive the Raidset.
What happened: The Raid5 over 4x 2TB WDGreen Disks degraded and I accidently marked the wrong disk as spare (this was definately my mistake, failure before always happend on drive #3, this time it was #4…), next boot the raid was gone.
[tried to fix the problem using Linux commands but to no avail].
Has anybody any experience how to get further than this?
Yes, but the success depends on what exactly was done during troubleshooting. Unless the rebuild was forced on a wrong disk order, Home NAS Recovery is a definite answer to the question.
