Ok. Thanks to everyone that has helped thus far. I shall mark the topic as solved, and go from there.

🙄... I am an idiot. Yes, I forgot... However, I still receive this error:

Unfortunately, the gui will not permit me to change the fs. I can post a screenshot a little later. It is immutably set as 'auto'.

Thanks @JorgeB Unfortunately, I was unable to check filesystem successfully on disk 5, with/without -L. In fact, check filesystem is not available within the disk settings GUI page. File system status just show's '-' and the File system type shows as 'auto', and is unchangeable. Running xfs_repair -Lv /dev/sdh1 via the command lines shows: Am I out of options?

Good news - disk 3 is back up and running! Thanks a lot. Are there any steps I can take for disk 5 at all?

Disk 3 seems to mount fine in UD, so I shall proceed with the new config and report back.

Point noted about the extended tests. I shall run these tests as well. If one/more are on their way out, I shall replace them - as soon as I have recovered all possible data.

Thank you, @JorgeB. Smart tests indicate all drives are healthy - if these are to be trusted. And, at this point, I'm just trying to recover as much data as possible. Will your recommended 'new config' approach have any adverse affects on disk 3? i.e. is this my starting point, or do I need to go down a different route for disk 3 first. Thanks everyone

Thanks for assisting, @itimpi Unfortunately, I am unable to run check on disk 3:

Note, I believe there to be two different issues. 1. Parity and disk 5 Disk 5 failed (due to a faulty sata cable) and then my parity disk also failed, whilst rebuilding disk 5. Hence the no fs error. I assume there is no resolution to this...? 2. Disk 3 This disk is part of the encrypted array and just suddenly stopped mounting. I would like to hope this issue can be resolved...?

Getting straight to it - I know I have lost data. However, I would appreciate some help recovering/keeping what I can. This is the current status: Is there anyway for me to restore the 2 array disks that are suddenly inaccessible? On a side note, I just want to say thanks to the many contributors in this community - I have learnt a lot just reading over the years, and this forum has saved my bacon more than once! nas-diagnostics-20240512-0010.zip
