Just tried to access Tower but it was unavailable. I could ssh to it and found this in my syslog:

Something to worry about?

 

I can access it now, but some of the services I was running (SABnzbd, slimserver, bits of unMenu) are unavailable.

 

I'm running 4.5.4. Thanks!

Looked further back and had this last night:

Just tried to stop the array so I could power down, and the web gui just says 'Stopping....' no matter how many times I refresh.

 

Bit worried now...

That indicates that one or more of your disks are busy.

 

(The ones that still say "unmounting" are those that are busy)

 

You'll need to terminate the processes that have open files on those disks so they may be un-mounted. Once you do, the array will stop.

 

Joe L.

Something must still be accessing the drives.. check your processes..

 

Guess Joe was faster

What's the fastest way to find out what that process is ? (thanks guys!)

 

I've killed pretty much everything that isn't standard and it's still stuck on Stopping

fuser -cu /mnt/disk* /mnt/user

I'll try it next time - I had to hard reset it to get it working.

 

df -kh wouldn't show the disks as mounted - said file missing or something for both.

 

It's now doing a parity check so hopefully the data is ok. I'm a bit worried about those kernel traces
