Linuxhelp _ Technical Support _ Partition shows 100% full but is not

Posted by: knowledge Oct 27 2014, 03:18 PM


I have updated my CentOS 6.5 - 64 bits which is running solusvm Openvz Master using the command: yum -y update.
When the update finished i have rebooted my server and the new kernel has been applied ( 2.6.32-042stab093.5 ) but, i have serious issue with the partition /vz which is shows as 100% full but its not full.
I am able to add data in this partition.

Any assistant will be appreciate.

Below is the out put from: df -h

[root@node ~]# df -h
Filesystem Size Used Avail Use% Mounted on
/dev/mapper/vg-root 49G 17G 30G 36% /
tmpfs 7.8G 0 7.8G 0% /dev/shm
/dev/sda1 243M 144M 87M 63% /boot
/dev/mapper/vg-vz 852G 817G 0 100% /vz

Thank you!

I assume your /vz file system is either ext3/4 which means that by default 5% of the total space is reserved for root. So once you go over 95% it will show 100%.
With a data partition you can safely lower the amount of reserved space using the tune2fs command.
