Recover RAID 5 Volume/Partition on OSX
Posted: 04 Oct 2015, 15:48
Hi,
I’m in urgent need of you guys assistance regarding an issue with my Raid won’t mount to my OS X Server. Not sure if this will help you guys but i will try to explain and give you as much info as possible. What happened was after i installed Stellar Partition Manger i went Disk Utility to create a boot disk for the OS X Server’s 500GB SSD and restarted. After restart I am able to Raid Volume under Disk utility Only and and SoftRaid but i can’t mount it.
What OS X Server consist of
Mac Mini 6,2
500 GB SSD (Use as boot and Plex Data storage only)
3TB Western Digital External HDD.
3 Partition
(1.4TB) - Use for OS X TimeMachine Backup
(.6TB) - Use for Windows Acorns Backup
(1TB) - Misc
SoftRaid
4 (4TB) Western Digital Red HDD
Setup as RAID 5.
One of these Picture will show that it is (UNKNOWN FORMAT)— <—maybe this is why i can see it but can’t mount it…
I contacted the the Softraid vendor for support and also purchased Diskwarrior 5 from their recommendation and unfortunately they are unable to assist.
After that i googled i somehow ended up here..
I'm pretty sure it had something to do with "Stellar Partition Manger" because up to this point it was working great! So i would conclude its a Damaged/Corrupted OS X partition.. Now the attached pictures FDISK said "GPT PMBR size mismatch (457179135 != 457179647) will be corrected by w(rite)" but Gparted said my partition is fine.
Im currently analyzing 1 out of 4 (4TB) and its taking "FOREVER"....
I apologize if this post is lengthy and if some of the pictures are irrelevant but i really did google and search this forum to the best of my ability but still am unable to get figure it out..
THANKS FOR YOUR ASSISTANCE!!!
