virtfs, What can I do to decrease the directory as Disk space nearly 100%

[songdapeng]

Dear All,

as I use Cpanel and my server disk space only 30GB for website but the virtfs directory use 15GB. I know that this is a important directory of CPanel but there is nothing I can do with this to decrease my space of server?

Hey there! It's important to note that VirtFS is not actually taking up any space on your machine. We have additional details on this here:

What is VIRTFS and can I remove it?

Question What is VIRTFS and can I delete it? Answer From the file "/home/0_README_BEFORE_DELETING_VIRTFS": The /home/virtfs directory contains critical operating system files. If you remove /ho...

You'll want to look to other areas of the system to decrease your disk usage, and you may find the following article helpful:

but my disk server is nearly. Do you mean no need to care about it?

[[email protected] ~]# df -h

the system show I used 94% and available 3.1GB, You just tell me that I still have 15GB available by not counting the VIRTS directory?

/dev/vda2 50G 44G 3.1G 94% /

Thanks for the additional details. I'm not disagreeing that your machine isn't full, but I am saying that you can't delete data from virtfs and that isn't included in the calculations. You'll want to find another area inside / where you can remove data.

 

[songdapeng]

so If I can do nothing with it, it's mean I lost 50%(15GB) of disk space to Cpanel to store information. why it's so big like that? I think it's just configuration.
Any Configuration to set the information to storing on the VIRTS

No, it doesn't mean that at all. VirtFS uses a series of bind mounts and doesn't take up actual disk space on the system. You'll want to find another area where you can clear up data from.

Here is a slightly different explanation of that area on the machine:

/home/virtfs/ is using up large amounts of disk space

Symptoms You may see significant disk usage reported for /home/virtfs by some utilities like the following example. -bash-4.2# du -h --max-depth=0 /home/virtfs/50G /home/virtfs/ Description ...

I checked my some linux team, It's seem like your virtfs really take up disk space.
my drive has 50GB, but the Virtfs take 30GB. so bad

If you try checking a file inside VirtFS and comparing it to a file outside of VirtFS, you'll see they are actually the same inode, so it is not additional disk space used by the system. This is a well-known issue with VirtFS, and not the cause of your system being low on disk space.

It seems your entire server is only 50G, which may just not be enough space for all of your data plus the operating system.

Thank you very much for your reply.
Yes, from my checking,
my / path has is 50GB for disk space and /home include all websites exclude virtfs only 11GB and VIRTFS take 30GB
as guide, the virtfs is not take any disk space, but when my disk used 100%, I can't upload any file to it.

I checked the virtfs inside, there're only fews domain account on it, why not store all?
so I can disable any think or do something to make the virtfs resource decrease?

 

[songdapeng]

In case I expand my disk space from 50GB to 200GB, I really sure that my website can use only 50GB and VIRTFS will take resource 200GB

VirtFS will only get created for users with jailshell access for SSH, so it is normal it may not exist for all users on the machine.

As I read the user guide for disable and remove the jail shell. but it's not work

There is no way to completely remove VirtFS from the system.

sure, I just think it should can decrease disk space of virtfs from 14GB to 10GB

Hello there, did you try checking what exactly occupies your disk via some commands? Like this, for example:

du -hsx /* --exclude /home/virtfs 2>/dev/null | sort -rh | head -10

 

[songdapeng]

Yes.

[[email protected] ~]# du -hsx /* --exclude /home/virtfs 2>/dev/null | sort -rh | head -10
8.3G /home
6.8G /usr
6.3G /var
802M /opt
348M /boot
309M /root
97M /run
64M /etc
2.6M /tmp
364K /error_log

 

[Futureen]

Yes.

Well, it would appear that you have plenty of free space in case the first "df -h" output in the thread is to believed and you have 50 GB of root partition. What's the exact issue? If If you run "df -h /", does it show that you have around 25GB of disk space free?
