Hello Everyone,

 

I am running Unraid 5beta14. It has been running well for me, and by itself it has no issues, however I started adding packages to it which all installed fine, and then after a reboot, the array will not shutdown. I get the error:

 

Retry unmounting disk share(s)...

 

over and over again on the webgui. I am pretty sure that this is because there is either a hung process, or a process, that refuses to quit. I am new to linux, but not new to computers and troubleshooting, and I know I could probably figure this issue out via process of elimination, but I was wondering if someone knew a better way. Here are the current packages I have installed via unmenu.

 

AirVideo

bwm-ng - Bandwidth Monitor NG (Next Generation)

cxxlibs-6.0.9-i486.tgz library accidentally left out of unRAID 4.4-beta2 through 4.5beta5

hdparm - get/set hard disk parameters

iStat - Server monitoring for the iPhone

Jre - Java 2 Platform Standard Edition Runtime Environment

lsof (list open files)

Monthly Parity Check

mysql (SQL-based relational database server)

openssl (Secure Sockets Layer toolkit)

python (object-oriented interpreted programming language)

python-cheetah (python template engine)

reiserfsprogs version 3.6.21

rsync (remote file sync)

SABnzbd

SMART tools (smartctl hard drive monitoring utilities)

SQLite (simple, self contained database engine)

unrar (rar extraction/compression program)

infozip (Info-ZIP's zip and unzip utilities)

 

Thanks for your help.

This means that something is still using your disks, try out the following:

 

My array will not shut down after I have told it to.

 

WARNING: Only do this if you are comfortable with linux commands, if not, wait it out and if all else fails reset the system (this will result in a parity check)

 

1. Telnet into the system.

2. Do a ps -elf | grep mnt and see if something recognisable is still at work

3. If not try ps -elf | grep disk and see if something recognisable is still at work

4. KILL <processid> (the number at the start of the line giving the ps -elf results)

5. Wait if array shuts down, if not, back to 2

Hello Helmonder,

 

That is extremely useful information. My box is running a full parity check right now, but I am going to test this, the next time I power down.

 

Thank you

Usually when my array wont stop trying to unmount, it is almost always a locked file.

I usually just go into unmenu and look at the Sys info tab and hit the "open files" button

 

the last time it was hung, my mover script was moving files.

the time before that, my MAC had some stupid .DS_Store file open. (bounced my mac and the server shutdown)

Actually I think I may have found my exact problem, and now of course, I feel dumb :-)

 

Check out this link:

for the following:

sabnzbd

sickbeard

couchpotato

python

 

it specifically states the following:

WARNING:

These applications will keep the cache disk busy and it will not unmount when you press the "Stop" button for the unRAID array. You must shut down these applications to be able to stop the unRAID array. Use the web interface for each program to shut it down or use the unMENU shutdown button to shut down all the applications with one click.

 

I was not doing this, thus most likely the cause of my problem.

 

Thanks everyone.
