Issues on my ReadyNAS 516, System Volume root useage 93%

So I've been getting this Error Message System Volume root usage 93%.

 

So I'm pretty sure it's PLEX.  I need to figure out how to move it's Database over to the Media side.  I think it's the Video Preview thumbnails really eating space up.  So I turned that off in PLEX and then hit Delete Preview thumbnails.  So that should have cleared up a lot of space.  It looked like it did.  But looking at other posts, I did this whole thing.

 

root@READYNAS:~# mount --bind / /mnt
root@READYNAS:~# cd /mnt
root@READYNAS:/mnt# du -csh /mnt/*

3.4G total

 

 

So I know there is a 4 Gig limit.  I see 3.4 gigs here.  I know there is a ton of space plex is no longer using but it doesn't seem to have fixed anything.  The AntiVirus fails to update, and if I try installing say EMBY, that fails, unless I do the older version from the avalivle apps area.  That installs!!!

Apps are supposed to put their data in /data/.apps, which is mounted as /apps on the root.  Some don't do that as they should - but plex does.  I have it installed on my RN202, and am only using 16% of the OS partition on that machine.

 

Thumbnails are stored in /apps also - in the case of the RN202, they are in /apps/plexmediaserver-annapurna/MediaLibrary/Plex Media Server/Media/localhost

 

So I think your guess on the cause is incorrect.

 

I have seen plex sometimes fill up the OS partition with temporary transcoded files, but that doesn't appear to be a big factor here.

 

As far as where the space is going, the big offender is 

1.4G /mnt/opt

This folder has about 4.6M on my RN526.

 

This folder (although still fairly small), has more in it than normal:

185M /mnt/root

Mine shows 36k.  Normally this folder just contains some hidden files/folders (.bash_history, .bashrc, .profile, and .ssh)

 

These two are also larger than what I have:

940M /mnt/usr
817M /mnt/var

My usr folder is only 243M, and /var is 612M.

Re: Issues on my ReadyNAS 516, System Volume root useage 93%

I'm using the program WinSCP to look at the NAS.  It's showing my Apps in /apps/

The MediaLibrary is in /apps/plexmediaserver/

 

At the time when I had the Video Preview Files turned on in PLEX, it was eating up 130+ Gig's all by it's self.  I keep getting the e-mail "System volume root's usage is 93%. This condition should not occur under normal conditions. Contact technical support."

 

I have over 1200 Movies and 5000 TV episodes.  So it's a big database and having The Preview thumbnails ,which is nice, taking a huge chunk of space.  Turning it off reduced the space used, but for some reason I'm still at 93%.  I have 20TB of Data with 10TB of free space.

 

I just looked and the Plex MediaLibray is down to 46.8GB.  That's like 1/3 of the size it was.

 

I don't know what I'm missing here.  

 

It'll take days to backup.  Wipe the NAS, Days to copy everything back.  Days more to get the software I use installed and working again like it should since some I have to manually SSH install and setup.   Remember how I had to do everyone once again, Ouch.

 

If it's not PLEX, then what in the world could it be eating up all the space?

Not the best way to investigate ... use the Linux shell.

As @StephenB already mentioned - /apps/ does not reside on that root partition the warning email is about...

 

root@RN628X:/mnt# df
Filesystem 1K-blocks Used Available Use% Mounted on
/dev/md0 4190208 740096 3053888 20% /           <<<<< this is what your warning e-mail is causing!!!!
...

/dev/md127 323185536 208920 319821608 1% /apps     <<< this is where your Plex media library et all does reside. That's all fine.

...

 

(Don't worry about my device low capacity on my /dev/md127 - this is an all SSD system serving a specific applicaion.)

Stephen already pointed to the sections residing on the root partition - these are the folders to investigate!

 

If your Plex library is 50 or 150 GB can't be relevant  as this is outside of the root volume. Again, WinSCP does show a complete tree, easy to overview mounts and symlinks going past a volume...

And you should already have seen that, since /mnt/apps is completely empty in your earlier post.  The NAS root has several mount points where portions of the data volume are mounted.  The whole point of re-mounting the root as /mnt is to let you analyze the root itself (without those mount points getting in the way).

 

Look in the folders I pointed you to earlier.

OK, I'll start looking more as soon as I get off of work and I'll have some time until the end of the weekend before work again.  I know I got a message today that it was at 92%, so it went down 1%. Is there something I should look out for that could be eating up so much space?

 

It was also a week ago where for whatever reason I couldn't get on my NAS.  My password just wasn't working?!?!  So I ended up doing a OS Reinstall.  I have a new longer password.  That was working.  Then later it stopped working?!?!  I was like not again!!!  But I left it alone and came back the next day and it was working just fine again and I havn't had that problem sense.  I thought that was a little strange.

The problems you are experiencing are likely all from the over-full OS partiton.  If you don't fix it fast, you may lose all access to the NAS.
