Re: [Xen-API] problem accessing lvmoiscsi vhd : libvhd::vhd_validate_footer: invalid footer cookie:



Hi Denis,

This sounds possibly like a different sort of failure to the hotfix issue. Can you run an sr-scan on that SR and check the output. See if you get a failure and entries in the /var/log/SMlog file that indicate vhd-util scan was unable to read VHD headers.

Thanks,
Julian

Hi everyone,

this is my first post on this list, I hope I won't be off topic (Dave
Scott's last post make me think that VDI issue are covered here).

I think I have a VHD that has been victim of the bug covered in the
Hotfix XS56EFP1006 (http://support.citrix.com/article/CTX129267). I've
attached a /var/log/xensource output below.

I'd like to know what are the option to get the data in that VDI? Is it
possible to apply the fix on a XCP 1.0 pool? (2 servers, storage on
lvmoicsi).

Thanks for the help,

Denis
