You may need a full reinstall, making sure to install with a RAID5 configuration.

Okay but, How Can I do? I sent a ticket them but; they didn't answer.

That should give you a clue of where is your space. Also, you can post the output of "df -h"

Help me please!

That's an option. Other alternative is that one of your VMs is using too much space. Check this:

cd /vz
du -h --max-depth=2 -x
That should give you a clue of where is your space. Also, you can post the output of "df -h"

Did you set the disk partition up correctly? https://documentation.solusvm.com/di...S/Partitioning

/ 10GB
512 Swap
/vz should have rest of the disk space allocated

so you should already have that mounted.

Could you show us your "fdisk -l", please? also, your server name or order number, so we can see if yours come with hardware RAID or software RAID.

If it's software raid, you will have some flexibility on the partitioning, though the installation manager in the OVH Control PAnel will force you to have, at least the system drive in some sort of redundancy.

Thanks.
