Unmountable: Unsupported partition layout after upgrading 6.8.? to 6.9.0

Recommended Posts

Since I updated/upgraded the Unriad server to version 6.9.0 the Disk1 of the array says "Unmountable: Unsupported partition layout" and Partition format says "factory-erased", but that was not the case: it was formatted, running fine and filled to the brim with data when it was running under Unraid 6.8!


I did a maintenance mode check on it like it was recommended on this forum: 

But it didn't seem to fix the problem. 

😢Sadly I have no parity secured array to recover the disk with, because two of my disks have errors and where disabled by the system and I yet have to RMA them. 1 of them was the parity drive. 

🍀Luckily I still got warranty on both those drives. I got the impression both disks where from Amazon. And I am not so confident that Amazon handels these harddrives well enough. 🤔


🙏Hopefully only the Steam game library was on there and can be redownloaded. 

I like to know if there is anything that can be done to fix this before I throw in the towel and format the drive for the array.

Anyone got any idea if this can be fixed?

Disk check gave this:


Phase 1 - find and verify superblock...
Phase 2 - using internal log
        - zero log...
        - scan filesystem freespace and inode maps...
        - found root inode chunk
Phase 3 - for each AG...
        - scan (but don't clear) agi unlinked lists...
        - process known inodes and perform inode discovery...
        - agno = 0
        - agno = 12
        - process newly discovered inodes...
Phase 4 - check for duplicate blocks...
        - setting up duplicate extent list...
        - check for inodes claiming duplicate blocks...
        - agno = 0
        - agno = 12
No modify flag set, skipping phase 5
Phase 6 - check inode connectivity...
        - traversing filesystem ...
        - traversal finished ...
        - moving disconnected inodes to lost+found ...
Phase 7 - verify link counts...
No modify flag set, skipping filesystem flush and exiting.

Download 6.8.3 from DOWNLOADS page and replace all bz* files on flash with those from download.

I did what you said and went ahead making a backup of the entire USB for: "just in case". 


Now my server is back up and running 6.8.3 AND it shows Disk1 agian!! Awesome! 👍🥳


I didn't knew changing versions was this easy. 😎


O: I only had to reactivate the cache pool - good that I made a screenshot earlier for the right order. 


Should I stay on 6.8.3 or try again with 6.9.2? 🤔

It gives for Disk1:


00000000  00 00 00 00 00 00 00 00  00 00 00 00 00 00 00 00  |................|

000001f0  00 00 00 00 00 00 00 00  00 00 00 00 00 00 55 aa  |..............U.|


What does this say about this disk?
