Hi,
I just did a fresh install of this distro a couple days ago, I went with the default partition options. I believe I recall 3gb for root partition. I just noticed during video playback a warning flash on the screen that the root partition is 90% full. I haven't downloaded any themes yet, haven't done much really except for fuss with a sound issue for a while, and schedule some recordings (football games etc.). Is there anything that might take up more space over time, perhaps logs, that I need to disable or manually purge now and then? Or should I perhaps re-install with a larger root partition, say 5-10gb?

Thanks
David J.

By default, we use a 5 gig /. Over time, /home/mythtv will start to consume more space. You can more /home/mythtv to /myth and symlink it. jams has made accommodations for this in R8 with a new filesystem layout.

Hi,
I went ahead and did this, stopped the backend first. I did a mv /home/mythtv/* /myth. Managed to create the symlink by doing:

ln -s /myth /home/mythtv

got a "myth" link under /home/mythtv that pointed to -> /myth. So I moved /home/mythtv to /home/mythtv.bak, and renamed the "myth" symlink to mythtv in /home, so that I have:

lrwxrwxrwx 1 root root 5 Dec 31 18:41 mythtv -> /myth

Does that look right?
Restarted the backend/fronted, I apparently missed some files in the move because my theme, and some settings were back to default, and I actually can't change the theme. Are there some permissions I need to change as well? Thanks.

You probably want to isolate the home dir on the /myth partition rather than dumping to the top level as I believe you did... in other words:

Code:
# mv /home/mythtv /myth/mythtv-homedir
# ln -s /myth/mythtv-homedir /home/mythtv


I'm guessing that you left behind all your .files and .dirs in the original /home/mythtv since you moved it via the command you posted and not the one I did :)

We might be putting the cart before the horse... before you move the homedir, you should verify where exactly the bloat is occurring; it could be /var/log for example.
1) Restore the original /home/mythtv by manually moving the files back to /home/mythtv from /myth
2) Post the output of: sudo du -hd 1 /

Ya that is what I did :(. I'm not sure what content belongs under /myth originally, other than the "tv" directory, to know what to move back. I can guess at most of it though. The ls output is:

Code:

Of course all of the hidden directories I imagine are home directory specific. Is "tv" the only directory or file that belongs under /myth? Thanks

No, there is more that belongs under /myth
I haven't run LH in a while but from memory, gallery, games, image_cache, ipodfeed, motion, music, phone, pretty, video, mythexport, streams

You didn't post the output of the du command to diagnose your thread title's problem...

Guess I don't see why your / partition is 90 % full.... if you moved your /home/mythtv back to it then you're total root usage shouldn't be near 90 % of 5 G.

Ballparking it, you have 2,260 MB of 5,000 MB used:

Yes I did move mythtv back to /home prior to running the du command. I'm still getting the message, just saw 94%. Perhaps I will try symlink again, correctly this time, to see if that helps.

Code:
107G    /data


107G for data is very large. My /data is 443M.

Here is the output from doing "cd /myth; ls" on my LINHES 7.2 machine in case that helps:
Code:
archive  games        miro        pretty     stream          video_stuff
backup   image_cache  motion      -------    system_backups
-------  ipodfeed     music       -------    tmp
------   ----------   mythexport  ----       tv
gallery  -------      phone       ---------  video


The dashes ("----") are directory names I've wiped out because they are directories I created and are not a part of the standard LINHES install...

I was seeing the message on my new frontend only install and have not had the problem since I:

Code:
sudo pacman -Sc


The arch wiki suggests this can cause problems and suggests adding to /etc/pacman.conf
Code:
CleanMethod = KeepInstalled


https://wiki.archlinux.org/index.php/Pacman_Tips

In my pacman.conf CleanMethod = KeepInstalled is commented out.
Others here can probably advice on the risk of doing this especially on a backend install.

Yes, /var/cache/pacman/pkg can fillup over time and purging it should be fine as you posted. Bleachbit is another method to keep unneeded files away. Dunno if it's in the LH repos or not.

cacheclean runs on the weekly cron job (/etc/cron.weekly/cacheclean.cron) and is set to keep the 3 newest packages in the cache.

Thanks all for the info. I did do the symlink of /home/mythtv to /myth/mythtv-homedir but perhaps I didn't need to with this latest info (?). I did to the pacman -Sc command, my /data directory went down to 65G. But that is not in the root / partition, correct? Anyway I have not notice this message again but I haven't watched much this evening.

On my LINHES 7.2 system, "/data" is on the root partition. Perhaps you are on a new version that things have changed. I am still surprised that you have 65GB in that directory...
