I have a 6 disks array under 4.4.2.  After I just copied a file off to disk1, I went into the gui and clicked on "stop" to shutdown for the night.  After I refreshed the page, I found 4 out of my 5 drives now showing unformatted status.  I went to copy the syslog from the flash drive and it only shows entries up to 2 hrs ago.  What just happened?  I have no rebooted or shutdown the box.  As I want to leave it as is until I find out what happened.

 

additional information: I had another user who had a windows explorer open on disk3 when I hit the stop button.  That drive is the only one that is still shared.  Could the stop have failed due to an user sitting on disk3 and causing unraid to stop only the other 5 drives?

syslog.txt

picture is worth a thousand wrods:

 

The open file on Disk 3 is preventing the array from stopping.  Close that file and then you can stop the array.  Then it will be fine.

 

Or log in via telnet or go to the console, and type

 

lsof /mnt/disk3

 

And find the process that has the file open and kill it.  Then the array can be stopped.

Exactly, and DO NOT press the format button.  The other disks are not un-formatted.  It is just that they have become un-mounted, and the display incorrectly shows un-formatted instead of un-mounted.

 

One disk remains that is busy that cannot be un-mounted. (disk3)  It could be an open file being read or written, or, you started a process when cd'd to a directory on that disk, and it is the current working directory for a process.

 

As stated, stop/kill that process and the remaining disk will be un-mounted.

Thanks guys.  The windows box was shutdown and I was able to "stop" it again.  Then after starting, everything's back to normal.

I was copying files to a few of the disk shares when I woke up to find this (attached image).  After reading this post, I closed all files and rebooted both PCs that were transferring data to the share.  I stopped and restarted the array several times.  I've disconnected the PC mapped drive to the \\tower\share.  I've ran > lsof /mnt/disk5 and nothing is returned.  Is it safe to stop the array and just reboot?  I would appreciate your insight.

 

Disk5 has a process running on it, or, a process using it as its current directory. (make sure it was not you cd'd to disk5, so log off or cd "/")

 

Or, perhaps the process that was present is no longer there.  Press "Stop" once more.

 

Since you have no parity drive installed, you do not have to worry about re-calculating parity on a forced shutdown.  So if you need, just power down.

Once again Joe, I appreciated the quick response on this Holiday morning.  I restarted the server and everything is back.  Thankx
