OMV 1.19 armhf RPI2 root file system at 100% !

forsaken006 · 26. Juni 2015

After updated and re-installing over and over for over couple weeks now. I have figured out what has been causing so many issues with omv on my RPI2.

The Root file system is full! Anyway to fix this or extend it? I have a 32gb microsd card in my rpi2 and much of that space is not in use.

Code

/dev/root shows 100%!

Do this via ssh if you can:
apt-get clean
rm /var/log/*.gz

Then do:
df -h

See how full it is. Maybe you have a bad rsync job or something. Also, if you do not add a RTC module you will be blowing all kinds of errors that fill the logs.

forsaken006 · 26. Juni 2015

I did those commands as root in putty with no change. It shows about 3mb free on the web gui. I dont have a RTC for it.

tekkb · 26. Juni 2015

I tried to get you in the web gui but it is still too full. You need to find what is taking up so much space. Usually a bad rsync job casues this. Did you have any rsync jobs???

forsaken006 · 26. Juni 2015

I was just trying to toy with 2.0 too. I upgraded a few minutes ago. Still no change in the size of the file system. This is a fresh install btw. I had to whipe it several times because i constantly get error popup messages in the web gui. "error - commonication error".

forsaken006 · 26. Juni 2015

no rsync jobs setup

forsaken006 · 26. Juni 2015

Plex and smb/cifs are the only things enabled. But plex is red on that list on the new stone burner menu.

**Plex just turned blue**

tekkb · 26. Juni 2015

Yeah, you get that error probably at like 85 percent full. You start filling logs like crazy above 80 percent with warning that drive space is low. It is best to always keep system drive well below 80 percent full.

Give me output of this now:
df -h

Red dot just means it's not running.

it is a 32gb sd card - how can i make the root fs bigger? Where is a good place to get a RTC for the RPI2?

tekkb · 26. Juni 2015

How big is your sd card again? You created another partition on it? Your rootfs is too small.
It needs to be increased.

What all is on this /dev/mmcblk0p3?

forsaken006 · 26. Juni 2015

No other partition was created on the MicroSD card. It is a 32GB card. Only what the img file created with Win32DiskImager.

How can i increase the partition size?

tekkb · 26. Juni 2015

Ah, it is the one that Aaron put on the image. When no drive is mounted there are errors. That is why he does this. Just a minute. I get some info.

In OMV's web gui:
unmount rrdcache filesystem
delete rrdcache filesystem

Then in command line:
fdisk -l (to list the partitions which gives the /dev/mmcblk0 )
fdisk /dev/mmcblk0
p
d
3 (should be mmcblk0p3)
w
shutdown -r now

After reboot you can use raspi-config to expand the root filesystem.
It seems the kernel has to release the old partition table. This will not be done til reboot. (I believe there is command to do this too)
I think if you expand root filesystem before you are using the new partition table you will corrupt filesystem.
So rebooting to new partition table may be key to prevent this.

forsaken006 · 26. Juni 2015

ok thanks!

tekkb · 26. Juni 2015

Here is information on how to add an RTC module too. I strongly recommend you get one. They are cheap, like 2-8 dollars US.

http://forums.openmediavault.o…-Stepchild-to-Wunderkind/
PS- Once you enter raspi-config you will see option to expand drive to full size of the SD Card.

forsaken006 · 26. Juni 2015

Awesome! Thanks a ton! Also, what is the overclock setting that you use for your rpi2? I had mine set at 800mhz. Should i set to 900? or back to 700?

tekkb · 26. Juni 2015

I used to be a gamer. You are running this as a server. Do you really need an overclock??? I don't use one. I just laugh at this overclocking the RPi stuff. It is much better than the old Pis. It is up to you man.

forsaken006 · 26. Juni 2015

You fixed it! I just want the most performance for my rpi2 Plex server :). I am a part time gamer currently - the navy and my family take up most of the time that i used to spend playing games...

I just remembered. There is something else important to watch on the pi. Let me get it.....................

forsaken006 · 26. Juni 2015

Oh, do you think that my 8GB USB 2.0 drive will be ok for the plex database? It is 55% used so far. Or should i just use the root fs for the plex database?

Jetzt mitmachen!
