Rebuild after disc failure super slow, other disk problem any fixes?

[JorgeB]

Xfs_repair should fix the filesystem, possible with some data loss, look for a lost+found folder after it's fixed.

Hi, sorry if I'm being dumb again, to rebuild disk 8 I unassigned it shut down and put in a new disk but when I assign it says its wrong as per below and I cant start the rebuild.

 

Thanks in advance.

Rebuild disk6 first

You cannot replace disk8 with disk6 disabled and single parity.

Sorry I seem to be making a meal of this. Rebuilt disk 6  with new larger 2 tb disk, all seemed to go ok but after finishing it shows disk 6 as   Unmountable Wrong or no file system.

Thanks yet again.

So I think I have 2 options

1. Put old disk 6 in try a file system repair  then put in new disk 6 and rebuild again or

2. Just try a file system repair on the new disk 6

 

Is one of these options the best way forwards

 

Thanks!!!

Lots of read errors from disk8 during the rebuild, so the rebuilt disk is expected to have some corruption, you can try to check filesystem.

Ok so after fixing the file system on the new disk six it shows I have I gb of data whereas used to be 1tb so lost pretty much all of it couple more questions

Would I get better result if put the old disc 6 in, fixed filesystem and then replaced and rebuilt?

Is there anyway of me knowing exactly what data has been lost so I can try and recover from other sources?

 

Thanks again.

Mount the old disk6 with UD, assuming it XFS you need to change the UUID, that can be done in the UD settings, then copy what you can to the rebuilt disk.
