"Resuming preclear of disk" that doesn't exist


FreeMan

Recommended Posts

I've been having issues with my server locking up over the last several days, but I'll make a separate post about that soon.

 

In keeping an eye on that, I discovered this line in my syslog:

Jan 26 18:40:15 NAS preclear.disk: Resuming preclear of disk 'sdp'

Not only am I not currently running a preclear (nor was I before the system locked up), but I don't have a device 'sdp' as can be seen in the output of lsblk:

I just rebooted my server a few minutes prior to this point in the syslog, and I've attached the complete diagnostics.zip in case anyone can find anything interesting in there.

 

Why is my server claiming it's resuming a never started preclear on a nonexistent drive?

Nope. Haven't precleared a disk since... October?

 

I did have some issues during the preclear related to other parts of the system, and the server crashed a couple of times then, too. It's has OS updates since then, and I shut it down to put all the drives in 5x3 cages since then, too, so it's had a couple of clean reboots, as well. The current number of drives is the max I've ever had in the box, so there should have never been a drive mounted as sdp.

 

Weird...

 

I presume you saw nothing else that would cause any concern? If not, I'll just mosey along and pretend this didn't happen.
