Upgraded from 6.9.2 to 6.12.6 and just experienced this same thing. Force update solved it for me as well! Thanks!

Rebuild Complete! All is well again! I would like to express my sincere thanks to @JorgeB and everyone else that contributed to helping me resolve this. Was super stressed when this incident happened and i thought i lost everything but this is an awesome feeling today. First time ever posting in these forums and it's great to know such a helpful and wonderful community exists! Truly can't thank you guys enough! Cheers all around my friends!

Apologies, when you say "rebuild" is that a specific process or am I literally just stopping array, assigning the disk and starting it back?

All my content (or 99.999% of what i remember) appears to be there. So is the last step to stop the array, assign back disk4, and start back the array now so disk4 doesn't show as disabled/not installed? Current state, disk4 still unassigned. Thanks!

Nope, no lost+found there either. Doesn't it only get created if something is very corrupted? Is there a command i can use to easily serach and locate it if it does exist?

Started in Array in normal mode...See attached..I've been browsing through all of the folders on disk4 and i haven't been able to locate a lost+found folder.

Complete...

Put into maintenance mode...executed that command and received the following..see screenshot

It does not let me change it to xfs. When i select xfs i don't get the option to "Apply". All i can click is "Done" which doesn't save the change. When i go back to main screen it still shows as auto.

"The first step is to identify the file system of the drive you wish to test or repair. If you don't know for sure, then go to the Main page of the webGui, and click on the name of the drive (Disk 3, Cache, etc). Look for File system type, and you will see the file system format for your drive (should be xfs, reiserfs, or btrfs)." disk4 is not mounted and listed as missing so it just says Auto. Please advise....Thx

Thanks for the confirmation! I followed your steps very carefully and I can see disk3 mounted now and the contents are there! So current state is the array is started and we just have the new disk4 unassigned and that's showing as "Not Installed....Unmountable: not mounted". Diagnostics attached. Awaiting further instructions. Cheers! tower-diagnostics-20221006-1803.zip

Okay a couple of clarifications... 1) Do I need to keep the old disk3 connected still? Can I physically disconnect it and then proceed with the above? My plan was to disconnect the old disk3 now that we've rescued it and connect the replacement disk for disk4. Please confirm this is correct. 2) On the faq for ddrescue it had mentioned after completion you can mount the destination disk (in this case disk3) and copy contents to the array..I'm NOT doing that correct? Just want to make sure there is no assumption that i followed that direction in the post. 3) "ideally the emulated disk will now mount and contents look correct" --this is referring to the new disk3 that we ran ddrescue on? Or the contents from disk4 that died? Sorry just trying to understand for my own benefit because both disk3/disk4 were disabled with contents emulated. You had mentioned in a previous post it may be possible to retrieve data from disk4. Is my assumption that the "contents emulated" message from disk4 means that now that we were able to successfully retrieve the contents from disk3, disk3 together with Parity and the remaining disks holds the contents for disk4? 4) If my understanding of question3 is correct, how do the contents of old disk4 get onto replacement disk4? Or do i have it all wrong? Thanks!

Okay I've got the replacement drive for disk4. Please let me know how to proceed step by step. Cheers

Oh wait...but if my Parity drive is only 6TB i think that's the max size i can go right? I'm not allowed to have a data disk larger than parity?

I can get one easily. You mentioned it could be larger than the original right? Disk4 was 6tB but i'd love to get a 10/12TB if the process will allow it.
