Many thanks everyone for your help. Checking the diag log file and advise. Followed the suggested advise by trurl (URL link) and my data disk and parity are now all happy. Thanks again trurl.

mmm, the 192.168.1.207 is my ESXi server. The FCP is a bit of an odd one, unless its the data (LUN) share for the ESXi ......... So you'd recommend rebuilding the drive onto itself? No need for me to plug in another (3rd) drive into the array for safety? You'd suggest the rebuild onto the affected drive as it should be ok?? Sorry so many questions, I really should've had more drives and backups. Many many thanks for replies and help in trying to fix. This community really is great.

Sorry yes ment to attach. Done. goonas-diagnostics-20210809-2023.zip

Ran a parity check and the disks passed then few days later one seems to have failed. Details as:- 'Array operation' started, array unprotected. So one of the disks has failed? I can access the shares / data but am I on a ticking time bomb and I'll loose data? I have another exact replacement Disk can I plug that in and rebuild the array redundancy replacing the 'failed disk'? I imagine I'll need to leave the array up and plug in the replacement disk? Thanks for any help you can give.
