Local Storage Issue Xenserver

Dear All,

I have a major problem with our XenServer. It started with a vm not booting after a reboot of the host the other vm failed to boot. After some researching/digging around i discovered there was no more room for any logs, so i cleared out some of the old files.

The server appeared to be boot normally, until i tried to start the vm where i discover the error

Error: Starting VM 'Windows Web Server' - The VDI is not available

I tried to follow some instructions in a blind panic to resolve this by getting the host to forget the VDI for the vm, in order for the SR to be rescanned. It completed the forget command but when i went to rescan the SR i get this error

Scanning SR 'Local storage' - The specified  storage repository scan failed

I have been trying to follow this page

but i am now hitting issues, if someone could offer some advice i would be most grateful. I believe the issue to be the Local Storage SR

This is the server setup:

Dell Server (1U) with 2 x 73Gb HDD in a RAID0 < not my idea!
XenServer 6.1.0-59235p  

Thanks in advance.
