ERROR: Illegal division by zero at /usr/share/perl5/PVE/HTMLServices.pm line 154.

This is the error message i am getting.... Everything seems to be working as it should .. but wanted to know what it was.

This is on proxmox ve 1.7
 
Re: Error Message.. did search and cant find any information. Illegal division by zer

Seems the capacity of the boot disk is not correctly detected. YOu created that VM via the web interface?
 
Re: Error Message.. did search and cant find any information. Illegal division by zer

Yes from web. This error shows up next to master node under the cluster link.
 
Re: Error Message.. did search and cant find any information. Illegal division by zer

What is the output of

# df -P /

on that node?

What is 'rootfs'? That does not look like a standard PVE installation?
 
Re: Error Message.. did search and cant find any information. Illegal division by zer

This is a standard install from your ISO. It looks like it might be my ISCSI? THe size looks right.

Are you sure. A standard install should show the following:

Code: 
# df -P /
Filesystem         1024-blocks      Used Available Capacity Mounted on
/dev/mapper/pve-root  99083868  18665068  75385636      20% /
Note: '/dev/mapper/pve-root' instead of your 'rootfs'

You mount 2 fs on your /

Remove this line or mount it elsewhere :

proxmox1:~# df -P /
Filesystem 1024-blocks Used Available Capacity Mounted on
/dev/mapper/pve-root 19094236 1331404 16792900 8% /


Ok this is the output of df -P / now.

I know what the problem was.. I had changed the I.P. Address of my NFS mounts when i moved my Cluster from the lab to the production Datacenter. Even though i had deleted the old NFS mounts from the web console they were still there. I deleted them from FSTAB and now all is fine.

This is the new FSTAB

# <file system> <mount point> <type> <options> <dump> <pass>
/dev/pve/root / ext3 errors=remount-ro 0 1
/dev/pve/data /var/lib/vz ext3 defaults 0 1
UUID=dd1817ac-1f63-44f0-8f77-31b6dc2fd54e /boot ext3 defaults 0 1
/dev/pve/swap none swap sw 0 0
proc /proc proc defaults 0 0


Now what i dont understand is why the Old mounts were put here but the new ones are not?
