Sophos UTM 9 9.411-3 data disk almost 100%

Kenny Mesdagh

Hi everyone,

 

I have installed a licensed Sophos UTM 9 on Hyper-V. The VHDX is 40GB.

This has been running well for a few months but recently I've been getting mails that the datadisk is filling up.

When I logon to the webinterface of the Sophos, the datadisk seems the be only 12GB. It's now at 96%.

Why is this filling up so quickly? What can I do to stop the datadisk from completely filling up?

I've seen other posts suggesting to connect with SSH and delete stuff in some folders in Linux but I  have no idea how to do that

    40GB for the whole system isn't much. You should log onto the system via SSH (as root) and check, which folder on the data partition is consuming too much space.

    du -hsx /var/storage/* | sort -rh | head -10

    A reason for a fast growing data partition could be deferred downloads because of something that our Sophos Distributor recently called a 'download loop' in the web filter. Take a look at this thread:

    40Gb is really not enough. I would create a backup file from this setup, create a new and larger VHDX (at least 120Gb), remove the 40Gb VHDX and attach the new VHDX to the VM, reinstall Sophos UTM and restore the backup. That should take less than 30 minutes and save a lot of future headache about low free space. IMHO this would be much easier than trying to figure out what is consuming all the space.

    Be aware that the backup would not contain your logs and reports so, if that information is important to you, you should try kerobra suggestion first. But, really, 40Gb is not enough.

    I think it's crazy that a software firewall should need that much space, but it looks like I have no choice!

    Going to reinstall it tonight with 120GB VHDX

    I know, it seems exagerated. But consider that the setup has to create partitions based on the available disk space, and it will always favor the logging partition size over data and storage partitions. There's also the swap partition that, for most recent versions, equals the RAM size. Given this, I wouldn't recommend anything below a 64Gb disk for a software UTM.
