Unmountable: Unsupported Partition Layout (Solved)

[Posedin]

I need some advice. So i've spent 2 days trying to replace and rebuild parity. I also realized I did not format the HDD before replacing the parity drive.

 

After I upgraded and rebuilt party for 2 days. Everything looked good and docker was working as expected. I decided to upgrade 1 disk in my array and now its showing Unmountable.

 

Btw The HD are brand new and I need not format nor preclear them cos the process to preclear 1 hdd is more than 24h. What should I do from here? I still have the old Parity I removed from the array.

What version of Unraid are you using?   The 6.11.2 has a bug with handling partitioning/formatting drives larger than 2TB.

That would explain why you are having problems.    You should upgrade to fix this (the current release is 6.11.5).

I am in the process of formatting a drive can I cancel it and upgrade my Unraid?

If the upgrade was done with v6.11.2 you must rebuild again with the current release to correctly partition the disk:

 

stop array

unassign disk1

start array

post new diags.

I am in the process of formatting a new drive and I have 6 hours to go. I'll wait for the clear to find, then I will follow your steps.

 

Thanks

Server remains online during a rebuild.

The last time I tried the rebuild, all my docker went offline, I will try again after the formatting or should I stop it?

Don't format anything or it will also format disk1.

Well... It is already too late. The format started since yesterday. I assumed since they are new drives they need to be formatted. 

I will wait for it to complete or can I cancel it at 80% completed?

The problem is that it will format ALL drives that show as unmountable and that included disk1, not just the the new drives.   Since a format is treated like any other write operation this will also update parity accordingly.   This means as well as the new drives disk1 has also been formatted to have an empty file system.

 

What is the state of your backups?

That's a clear, not a format, just don't format once the clear is complete, before fixing the disk1 problem.

unfortunately, I did not initiate a backup. Is there a way I can access parity files and move them to my cache for now? I don't have a lot of data. 

I had 1 x  2tb and 2 x 1 tb before and I only used let says half of my 2TB capacity.

Thank you! I am also concerned cos Disk1 is showing 0 read and 268 write. I already went thru the replace/rebuild 2 days ago for disk1 to replace my 1tb.

There are no files on the parity drive(s).  In fact they have no file system.  Parity drives are just a "bucket of bits" with calculated values for the same position on all the data drives.

Thanks for your help. After following the above steps, Disk1 looks okay but going thru parity check. I will try the same for disk3 once the parity is done.

Here is the logs as requested.

Looks good fore now, disk1 is already mounting, just need to wait for the rebuild to finish, and you can now format the new disk3.
