Disk usage warning

magicalwonders · Aug 18, 2018

On the 11th August I received the following message from my server cPanel Monitoring -

Disk usage warning

The filesystem “/” mounted at “/” reached “critical” status because you currently use 93.95% of its available blocks.
Notification Type: critical
Server: webhost1
Primary IP Address:
Filesystem: /
Mount Point: /
Percent Used:
93.95%
Disk Block Usage:
Used: 1.32 GB
Available: 6.04 GB
Total: 100 GB
ChkServd Version: 17.0

My host ran a quota check which was supposed to put things right. However, today I received a similar message -

Disk usage warning

The filesystem “/” mounted at “/” reached “warn” status because you currently use 90.68% of its available blocks.

Notification Type: warn
Server: webhost1
Primary IP Address:
Filesystem: /
Mount Point: /
Percent Used:
90.68%
Disk Block Usage:
Used: 12.82 GB
Available: 9.31 GB
Total: 100 GB
ChkServd Version: 17.0

This time my hosting tech support is saying -

The email is just an informational email from CSF/LFD (the firewall software). All root emails to be forwarded to your email in WHM, and then all messages from the server are routed to this mailbox. The email is set in System Email Preferences inside WHM. You can set it to another mailbox if you don’t want to receive these messages in your personal mailbox. You can also tweak the LFD settings, thresholds and email notification preferences from the CSF Firewall menu in WHM.

This issue doesn't sound like it has anything to do with CSF/LFD ?

Can anyone advise?

NO that is not csf that is cpanel's disk warning.

csf does not check disk space

I didn't think so. I've thrown it back to my tech support. Hopefully I'll get someone who knows about servers! Lol.

Hi @magicalwonders

The issue has nothing to do with quota really either. Those are disk full % warnings indicating that your disk at / is nearly full. Your host should be able to provide assistance with this.

Thanks!

Hi Lauren,

My host is having another go at fixing this. The cPanel alerts seem to be not working properly. I received this alert today -

Percent Used:
94.45%
Disk Block Usage:
Used: 12.81 GB
Available: 5.55 GB
Total: 100 GB

The numbers don't add up. If I've only used 12.81 GB out of 100 GB, there has to be a lot more than 5.55 GB available?

is it an OpenVZ or Virtuozzo VPS or other container based VPS
if so they have oversold their drive space

Hello,

That is odd, it could be as suggested by @dalem but I would like to see what the output of the following is (if you have SSH access to the server):

Code:

df -kh

Thanks!

Hi,

My WHM shows CENTOS 6.10 virtuozzo

Here's the output of

Code:

df -kh

The output seems to only refer to the last cPanel account created. There are eight accounts altogether

HI @magicalwonders

What is this:

Code:

none 2.0G 4.0K 2.0G 1% /home/virtfs/newtestaccount/dev
none 2.0G 4.0K 2.0G 1% /dev
none 2.0G 0 2.0G 0% /dev/shm

Have you made modifications to virtfs or the mounts in general or has your provider? Can you provide the output of the following:

Code:

cat /etc/fstab
cat /proc/mounts

Thanks!

I haven't made any modifications. I'm not sure what my host has done. I'm guessing it shouldn't be like this?

Hi @magicalwonders

Based on the thread here: Using "none" in /etc/fstab it is legal to do that but not something I've seen previously. It does seem like the disk usage that's being reported is from the host node and this isn't something we'd be able to provide assistance for further, your hosting provider needs to address the disk usage issues on the host node of the VPS

Thanks!

Thanks for the update Lauren,

I'll let my hosting provider know.

Many thanks,

Hi @magicalwonders

Ok, let us know if there's anything we can help with once they look into it further.

Thanks!
