OMV System Disk Full

mc-iceman · 22. Mai 2013

Hi all,

(First sorry for my Englisch )

Im use 2. OMV NAS self build and the first makes problem with the System Disk!

The System Disk is a` 32GB mSATA SSD and the System is copy with DD if= of= from a 15GB usb stick.
Now after several days running not login via web or Terminal always the same not enough space, disk full ....

i`m showing with Ubuntu and well the disk is full 13GB, free 1GB i`m used gparted to change the disk space to the
max (29GB) and 1,5GB swap.

my question why fill OMV the system disk??

i`m using OMV 0.4.30, SMB/CIFS, SSH, Plex Nine and a 19,10 TiB raid5 with xfs

Search around the disk and see what is taking up all the space. We mostly see this with bad Rsync jobs. Have you been running any Rsync jobs?

Yes i`m think the Plex metadata use several space on the disk okay put it is not really the only one problem
then after reboot is over 1GB space free! now 14GB.

only one thing have i`m forgot after expand the disk have changed the uuid from swap its now fixit.

Code

swapon -a
swapon: cannot find the device for UUID=c9bcf0fc-0b58-4a26-a9ec-bacd406d4013


After fix:
swapon -s
Filename           Type	        Size          Used	  Priority
/dev/sdg5          partition      1568760       0        -1

i`m have deletet the extended swap partition to expand the system partition and then recreated.

however my two system have the same used disk space on the system disk 13GB!? and used the same three services SMB/CIFS SSH and Plex

Code

my little NAS OMV 0.3.10, 7 TiB Raid 0, 24GB USB 3.0 SSD stick, 8GB RAM and one i3 CPU:
df -h

and both system never use the swap.

up to now is the used disk space okay i`m must wait several day`s to see the result.

Thanks for your help

davidh2k · 23. Mai 2013

Swap will only be used if you ran out of ram.

You can look up the 10 biggest files/directorys on your system via

Code

du -a / | sort -n -r | head -n 10

And Hell you are running nice systems there...

Yes i test it but my problem is the raid is mounted.

try this to exclude these dirs:

Code

du --exclude="/proc/*" --exclude="/media/*" -a / | sort -n -r | head -n 10

Should result something like:

Code

896616  /

222876  /usr/share
148724  /var/cache

Hope it helps

okay Plex used complete 10GB ??? include metadata off 6GB ??? it`s KB correctly?? that is very much but i think okay.

Thanks for all your help`s and Greetings
mc-iceman

ryecoaaron · 23. Mai 2013

Yep, that is KB. Plex seems to store way too much metadata and is causing problems with drive space for a lot of people. Guess I will start recommending a 40 GB+ drive if you are going to use plex

davidh2k · 23. Mai 2013

My Plex takes up 795MB, not so big at all. (No Movies, TV Series only)

Greetings
David

mc-iceman · 23. Mai 2013

i see! the metadata on the system disk is so stupid way ever give Plex never oder options in the settings.

i think i`m Delete all metadata and show what`s change! it is my first Plex system but not all in the Plex is okay.

See Tobias post. You don't need bigger disk. You just need to move your library to data disk on OMV and edit a line in /etc/default/plexmediaserver file.

Moving your transcoding location is a probably a good idea too.

You have quite a collection my friend.....

Well move the metadata is the best way but (/etc/default/plexmediaserver) is the wrong way! only what you must understand is the folder plexmediaserver in /etc/default is a user directory from user Plex!! Now only what you must do is move the user directory to an other device!! it is simple and the only right way.

Move user and directory:

Code

stop Plex
/etc/init.d/plexmediaserver stop


Move user and directory:
usermod -d /your path/plexmediaserver -m plex


start Plex
/etc/init.d/plexmediaserver start


check server running:
/etc/init.d/plexmediaserver status

i`m found the solution on the plexapp Forum http://forums.plexapp.com/inde…tadata+%2Bdir#entry381294

/etc/default/plexmediaserver is not a directory. It is a file used to setup some configuration options when plexmediaserver starts. In the default line you see for the Library path you see {home}. The path is just using the whatever is set as the home directory of the plex user. You do not have to use the home directory. You can simply put whatever path you want and just make sure it is chowned correctly. But if you want to have a config line like the original you could change the home directory of the plex user, but not necessary.

PS- They use both methods on the plex website so it not wrong to forgo using the home method.
