Unable to Mount drives after hardware change "Unmountable: Unsupported partition layout"

[air250]

Hi, 

 

I have recently upgraded my server hardware. My old server had an older controller that could only read drives up to 2.2T not knowing this at the time i installed 4T drives as some of the replacements.  The server continued to work but only allowing me to access T2.2 of the 4T it was not an issue at the time as i was moving from 1T so it was still over double the storage. I recently migrated to a new server that sees all 4T adn because of this some drives came up as wrong. So i did a new config and mapped the drives manually now i'm gettig "Unmountable: Unsupported partition layout" These drives can not be formatted they still have my data. How do i add them back to the Array?

Wait for @JorgeB.  And what format were they originally and also include your diagnostics

[JorgeB]

Assuming parity is valid a disk rebuild for all affected disks (one at a time) should be able to create the expanded partition, to test, stop array, unassign one of the data disks that show unmountable, start array, post diags.

I don't believe Parity is still valid I rebuilt the parity drive thinking I could not rebuild because more then 1 drive was not working 

- Also the parity drive was one of the drives that were the wrong size.

I rebuilt the parity drive

When? It's still showing wrong, or did o new a new config after that and re-synced parity? If yest that should be OK, as long as all the original disks were used, try what I posted above.

This an old screen shot I took before I did anything I since did a new Configuration and re-synced parity. yes the original disks are still in ill give it a shot. Really appreciate the help

It dose not seem to be working I have been stuck at 0.4% for 12 hours on the first drive.

That would be unrelated to main issue, did the emulated disk mount? Post current diags.

That's only the syslog, and it's empty, post the complete diagnostics.

Sorry hope this is it

It looks like one of my disks have gone bad in the migration and unfortunately it was not the one i started to rebuild I still have all drives -1 (the disk that failed) would it make sence to do a new config, put back the disk i was trying to change the portion size of and them try and migrate the failed drive. do you think that wold work? 

[JorgeB]

Yes, disk2 is failing.

It's wort a try:

 

-Tools -> New Config -> Retain current configuration: All -> Apply
-Check all assignments and assign any missing disk(s) if needed, including the new disk2 and old disk11, replacement disk2 should be same size or larger than the old one
-IMPORTANT - Check both "parity is already valid" and "maintenance mode" and start the array (note that the GUI will still show that data on parity disk(s) will be overwritten, this is normal as it doesn't account for the checkbox, but it won't be as long as it's checked)
-Stop array
-Unassign disk2
-Start array (in normal mode now) and post new diags.

Really Appreciate your help. You honestly have no idea. Please see attached

Emulated disk2 is mounting, that's a good sign, you can now re-assign the new disk there to begin rebuilding, despite the previous errors during the rebuild disk11 should not have been damaged, since Unraid will skip any sectors that cannot successfully write due to read errors, so old data should be intact, and if all goes well with the rebuild you can then try gain to fix the partition issue.

[air250]

It seems to be working!!! will take some time but at least there is progres. Thank YOU! ill keep you posted with the outcome.

[air250]

Just completed, the data looks to be intact. How should I go about remaining drives with the incorrect partition size. same process rebuilding the drive or is there a way to just resize the drive?

Same process, unassign one of those disks, start array and see if the emulated disk mounts, if yes and contents look correct rebuild on top, then repeat for the other disks.

[air250]

Everything looks be be up and running, Thanks Again for all your help rely appreciate it.

Looks good, all rebuilds were clean, without any disk errors, so all should be good.
