Regarding vhd-util binary
Hi All,
I had downloaded the vhd-util from http://download.cloud.com.s3.amazonaws.com/tools/vhd-util .
I have an vhd file in the NFS share. I had mounted in my mgmt. server and tried vhd-util read -p -n "path of file" it works.
But the same file when present in CIFS share, mounted on my mgmt. server with (rw) vhd-util is failing to read/dump the headers.
Is vhd-util binary has limitation reading file from CIFS.? Or we need to mount the CIFS share with any extra params?
Thanks
Rajesh Battala

I have seen problems with an out of date vhd-util, e.g. http://dlafferty.blogspot.co.uk/2013/08/using-cloudstacks-log-files-xenserver.html You could check that you are using the version of vhd-util you downloaded using "which vhd-util".
However, why don't you first rule out CIFS as the problem? Put the image on local storage, and try the command again.

Hi Donal,
I had mounted the cifs with rw permission. I was able to touch and write data to file and read it.
But when used vhd-util to query/read the the vhd files present on cifs am getting error.
root@rajesh-HVM-domU:~/testvhd# /root/vhd-util read -p -n /root/testvhd/template/tmpl/1/9/4382fd85-7259-4392-a9a9-4990718bd48f.vhd
Failed to open /root/testvhd/template/tmpl/1/9/4382fd85-7259-4392-a9a9-4990718bd48f.vhd: -22
/root/testvhd/template/tmpl/1/9/4382fd85-7259-4392-a9a9-4990718bd48f.vhd appears invalid; dumping headers
Thanks

Make sure your O/S support for CIFS includes read/write of files in mounted CIFS share.
E.g. use vi to create and then edit a file on the shared storage from your management server.

Make sure your O/S support for CIFS includes read/write of files in mounted CIFS share.
E.g. use vi to create and then edit a file on the shared storage from your management server.
