I recently had a drive fail, no biggie, its happened before. I replaced it with another drive and began the pre-clear. When I brought the server online to pre-clear, the drive shows "not installed" which makes sense, but there is no mention of emulation. Trying to access the shares on the server, much of the data is missing. on individual drives the data is present, but not in the shares. Before I create a larger mess, I was hoping for a little guidance as this is different than any previous drive failure I have had. 

 

I am running unRAID 6.6.6 

Attached is a copy of my syslog.

 

My principle concern is rebuilding the array with whatever state the system is in leading to permanent data loss - obviously!

 

I genuinely appreciate any help that can be offered.

Looks more like the typical SAS2LP problem, controller crashed causing errors on multiple disks, please reboot and post the complete diagnostics: Tools -> Diagnostics.

As soon as pre-clear finishes I will post that. 

The diagnostic file is uploaded. I would greatly appreciate help in figuring this out.

 

Thank you

Start the array to check all disks (including the disabled one) mount OK and all data is accessible, it should be, then you'll need to rebuild, is the unassigned 4TB Toshiba the old disk or a replacement?

I did start the array and performed a check. There were 0 errors found. The unassigned HDD is the original disk that needs replaced. I have a new one pre-cleared and ready to go in. It appears everything is available, which is concerning as it had not been after my last reboot. There is *some* problem lurking in the background.

Disk itself looks mostly fine, though there a few reallocated sectors, but the problem was most likely caused by the SAS2LP, it's a known issue and why those controllers aren't recommended for some time.
