Since we are providing VPS management service to our clients, sometimes the clients may raise support tickets saying that they are not able to access cPanel, WHM or webmail on their VPS.
The error was,
How to solve this
Pre-Requisites : You should have Shell access (as root) to the Node server.
Mostly this happens due to inode issue. The inodes allocated to the server maybe full. inode is a data structure on a traditional Unix-style file system such as UFS. An inode stores basic information about a regular file, directory, or other file system object.
Say we are logged into the Node Server. There we are going to list all the Containers existing on the Hardware Node. By default, only running Containers are shown.
[root@linuxvps1 ~]# vzlist -a CTID NPROC STATUS IP_ADDR HOSTNAME 100 18 running 126.96.36.199 WEB.EXAMPLE.COM 101 63 running 188.8.131.52 - 102 169 running 184.108.40.206 server2.example.com 103 81 running 220.127.116.11 example.net 78965 236 running 18.104.22.168 server1.example.com
Assume your container is 103. So simply enter into 103 by this command
[root@linuxvps1 ~]# vzctl enter 103
Check if the inodes are full in the container
[root@linuxvps1 ~]# df -i
Most Probably it should display something like this :
Filesystem Inodes IUsed IFree IUse% Mounted on /dev/vzfs 200000 200000 0 100% / none 65536 95 65441 1% /dev
Bang ! The inodes on /dev/vzfs mounted on / are full. You’ve to go nowhere else to see why that error was delivered. A simple solution will work out, you’ve to increase the inode limit. You’ve two options, either through Shell or through the Node Control Panel (like Parallels Infrastructure Manager)
First we will go through Shell mode with this command :
$ vzctl set veid --diskinodes softlimit:hardlimit
Where ‘veid’ is the VPS ID
root@linuxvps1 ~]# vzctl set 103 --diskinodes 7680100:7680200
Second we are going for Node Control Panel. In the infrastructure, you will see your VPS with a ! sign. That indicates your VPS is having some sort of issue.
So you’ve seen the Alert. Next access the VPS, go to Resources tab. I’m sorry to tell you that I grabbed this screenshot after resolving the issue, but it will help you anyway
You should see the ‘Disk Inodes’ is full under ‘Disk Usage’ category (Here it is not !). Next Click Configure to settle this one
See the Highlighted part, the inodes should be limited to some size. Increase it or remove the check mark to make it unlimited. Make sure you save the changes. Now try again accessing cpanel/WHM/Webmail. It should load with out any issues.That makes a smile in your face, isn’t it ? 😉
