Hello, I am new to This forum and I have a problem that i cant seem to find any information on. or at least is relevant to my situation.
I set up a HP MicroServer N40L fitted with 5 3TB Hard drives (one hard drive mounted in the optical bay) in RAID 5
I had this working for years until one day i discovered that the server wouldnt start up. CrystaldiskInfo indicated two of the 5 drives were Yellow and dying from bad sectors.
I removed the dying drives, did a ddrecovery of the data onto new donor drives and slotted them into the server.
drive 1 had 99.99% data copied, some bad sectors were unrecoverable. drive 4 had 100% data copied!
Upon booting I got the failed code 8 error message.
After crawling through the forum, not knowing what im looking for or what im looking at (im a linux command line n00b) i saw some people were having luck with the command:
"mdadm --assemble /dev/md127 /dev/sd[abcde] --verbose --force"
...so i gave it a try. Picture appended showing results.
As far as i can understand - 4 of the 5 drives are recognized and the filesystem is missing.
open media vault indicates ext4 filesystem but its 'missing'
honestly i'm at a loss as to what else i need to do at this stage.
Any ideas on how to rebuild this raid 5 partition to accept the two 'replacement' drives?
