I tried to stop my array this morning and its stuck "unmounting".  it has been unmounting for over an hour now.

 

Not sure what to do.  I cant access my shares to get the full syslog but i was able to connect via telnet and get a chunk of it.  this is all my activity from this morning.  the last couple lines are just repeated over and over again.

 

what can i do to get my array safely stopped and restarted?

You likely have something tying up a drive. Either an add-on program or you have logged-on and opened a disk on the console.

so two questions...

 

1) how can i tell exactly what is happening

2) how would i go about resolving it so that i can shut down my array?

type:

lsof | grep /mnt

to get a list of the open files or processes holding a disk busy.

 

Then, stop/kill those processes.

when I submit that command (lsof | grep /mnt) it just hangs and doesn't return anything and doesn't take make back to a prompt either.  just hangs.

Is there anything else I can try?

lsof /dev/md*

or

/usr/bin/fuser -mv /mnt/disk* /mnt/user/*

i tried both of these and still got the same result... nothing displayed and it didn't return me to the command prompt.  it just hangs there.

 

what could be wrong?  do i need to just hard reset the server?  is that ok to do?

 

well that kind of took care of itself...  a few minutes after my last post the power went out.  My unraid is on a ups but it would not shut down cleanly because of whatever was stuck.  SO the ups batter drained in about 20 minutes and the server shut off.  Power came back this morning and I powered it on and now it is stuck starting up the array for the past hour or so.

so here is the syslog from when i booted up... or at least as much as i can copy and paste from the telnet session:

 

edit: my array is now online and doing a parity check - i was able to get the complete system log attached.
