Configure Disk Usage Warning with Cpanel DNSOnly

I have a second server with DNSOnly. I also use it for offsite backup.

About a year ago it warned because of 83% disk usage on the /home partition. So I reduced the backup size.

But starting with 8th of August this year it warnes me at 77%. I cannot change this in WHM because the configuration is not included in DNSOnly.

How can I change this setting? Is there a configuration file?

Thanks!

 

Thanks!

Something is a bit strange: It was already configured to 82.xx (can't remember the last digits). And "df" also says 83% usage of /dev/sda2 (/home).

But the DISKWARN mail says 78.81%

df:

Code:

Filesystem  1K-blocks  Used Available Use% Mounted on
/dev/sda2      477091244 376039016  77183712  83% /home

The total space is 477091244 1k blocks. That's 454.99 GB - same value as in the mail.

df values in GB:
Used: 358.6 GB (78.81%)
Available: 73.6 GB (16.18%)
There are about 23 GB missing. I just read this is system reserved.
Interesting, that it says 83%. Maybe it adds the 5% system reserved space?

Values from the DISKWARN mail:
Used: 358.62 GB (78.81%)
Available: 96.37 GB (21.18%)

So CPanel uses the value like df does to configure and detect disk space warning. But then it shows the values in the mails without the system reserved space. Last year in November I also got disk space warn mails, but with a different layout and it started with 83%.

 

Thanks for the help and clarification!
