Shares not mounting

[Jocko]

Is it going to fail again very soon?

As soon as a new bad block appears again and impact the superblock then yes it will fail again.

Currently you have 560 bad sectors it is not so much and I assume your data should not be corrupted as the disk uses then some additional sectors to replace them
but their number is limited.
Note: if later some bad blocks concern fs partitions (sda1/2/7), the nas may start no longer.

What would you suggest next, backup to new drive and replace drive?

If you do not use heavily the cloudbox, I think you have time to buy a new disk and then backup your data on it

Can I risk, rebooting NAS and attempting rw mount?

Yes if you reboot the nas, you will get a rw mount on sda8
My suggestion is to keep down the nas until you get a new disk.

Thanks Jocko.

I'll bring the NAS up as normal and rsync to another NAS drive to complete backup.

I'll also start shopping for replacement drive.

Beer in the post! Many thanks!
