Low Disk Space Warning

  • Updated

One of the Nimbus Hosting platforms key benefits is that it remotely manages servers. This enables management of multiple servers from a single application, it also enables sites to be faster as it doesn't use a resource footprint on the servers. This does mean though, that a very small amount of free space is required on the servers so that the platform can send tasks to them.

 

When a server runs out of disk space the platform disables all features for that server as it would not be possible to run them.

 

Please keep an eye out for disk notifications to ensure that this doesn't happen.

 

If it does happen, not only will the hosting platform stop working for you but your sites will likely stop working too. So you are going to want to delete some data, maybe some old or dev sites. Trouble is that you cannot delete them via the platform as you are out of space.

 

So what do you do...

 

The good news is that you just need to free a small amount of space for the platform to enable the features again, then you'll be able to delete entire unused sites via a single click. But how do you delete any amount of data?

 

You can get a break down of the disk usage on your server through our Hosting Platform, simply select Disk Usage on the left hand side on the server's dashboard.

 

Up in the top right hand corner there's a switch where you can select either GB or MB, depending on how you want to read the information.  

 

 

The top section is the Operating system, configuration and application files, this includes the OS files, system logs, OS packages and other OS related files such as logs and configuration files.  Next is a break down by website of the files, database and log file sizes.  You can use the tick boxes on the right hand side to select multiple sites and it displays the total disk used.  Take a look and see if there's anything that doesn't make sense, a small, simple website that's using a lot of disk is a good starting point.  Then you need to try and clear some files or, if you have an unused site then you can connect to that and delete at will.

 

The best method for this is via FTP. See the guide below for accessing FTP for a site.

 

Accessing your FTP details

 

Disk usage looks to be ok and nothing to delete in a website?  Another option is to check the server via SSH. See some steps below:

 

The easiest way of checking this is to issue this command:

  • df -h

and the output should look similar to below:

Filesystem                         Size  Used Avail Use%

Mounted on udev                    975M     0  975M   0%

/dev tmpfs                         200M   24M  176M  12%

/run /dev/mapper/ubuntu--base--vg-root   33G   3.1G   28G  10% 

/ tmpfs                              996M  4.0K  996M   1%

/dev/shm tmpfs                           5.0M     0  5.0M   0%

/run/lock tmpfs                          996M     0  996M   0%

/sys/fs/cgroup /dev/xvda1                472M  110M  339M  25%

/boot tmpfs                              200M     0  200M   0%

/run/user/1003

In this example the one you want to pay attention to is the 33G partition, generally it will always be the largest partition you want to make sure has free space.

If the drive is 100% full you will need to try and clear some space to get back up and running again, the easiest way is to clear some log files, these logs are safe to clear:

 

  • /home/storm/logs/SITENAME/
  • /var/log/

It's best to clear out the archived logs in /var/log first by issuing this command:

 

rm -rf /var/log/*.gz
