Running low on storage

[GoWilkes]

I'm kind of confused by something, I'm hoping you guys and gals can shed some light on it.

My server is a CentOS 6.10 xen hvm, running WHM v. 78.0.49.

Under server information, I see that /dev/xvda2 is 99G in size, and I'm using 93G. But I have 477M left, putting it at 100%... what happened to those other 6.5G?

Also, tmpfs (mounted on /dev/shm) is 1.9G and uses 0%, and /usr/tmpDSK (mounted on /tmp) is 3.2G and uses 323M. Is there an easy way to shift 1.5G of tmpfs and 2G of /usr/tmpDSK to /dev/xvda2 without formatting or anything?

Hi @GoWilkes,

I'd suggest installing the ncdu tool to understand where the disk space is being used better.

@GoWilkes can you show me the output of the following:

df -kh

I'm so sorry to leave you hanging on this, @cPanelLauren ! I didn't get an email that you had replied, of course :-(

This is the output, though:

# df -kh
Filesystem      Size  Used Avail Use% Mounted on
/dev/xvda2       99G   89G  4.5G  96% /
tmpfs           1.9G     0  1.9G   0% /dev/shm
/dev/xvda1      248M   79M  157M  34% /boot
/usr/tmpDSK     3.2G  103M  2.9G   4% /tmp

I don't know why tmpfs and /usr/tmpDSK are so large, but I can't find a way to recover that space. I know that I'll have to upgrade servers in the near future, I'm just trying to push it off for as long as I can for financial reasons.

I've made a few modifications that have cleared up about 5G, though. One major change was to /etc/logrotate.conf: I set it to rotate daily instead of weekly, to compress log files, and then I added this when I saw that /var/log/munin was taking up over 3G by itself:

/var/log/munin/munin-graph.log
/var/log/munin/munin-html.log
/var/log/munin/munin-limits.log
/var/log/munin/munin-node.log
/var/log/munin/munin-update.log {
    missingok
    notifempty
    create 640 munin munin
}

Otherwise, my biggest hogs are MySQL and a few hosting clients that insist on keeping their emails on the server :-( So other than squeezing a little here and there, there's not much more that I can do.


Addendum:

I found a directory at /usr/local/apache.ea3/... I migrated to EasyApache 4 last year, and this looks like a bunch of log files that were just backed up. Can I safely delete this entire directory? That's almost 1G by itself.

There's also /usr/local/apache.backup/ and /usr/local/apache.backup_archive/... they're only 46M combined, but can I safely delete them?

I also have almost 1G of log files at /usr/local/cpanel/logs/archive that go back to 2014! Why aren't they rotating out? Can I safely add something like this to /etc/logrotate.conf ?:

/usr/local/cpanel/logs/archive {
    missingok
    notifempty
}
