Subject Re: Unable to mount Secondary Storage on SSVM
Date Tue, 12 May 2015 14:49:15 GMT
Hi All,

Finally I am able to mount Secondary Storage path on SSVM.

Our NFS Server Version is v3 and SSVM (Client) version is v4 (Present). So
I tried to mount manually with version 3 and it worked !!!

(Here on SSVM, I did #*man mount.nfs *there it is saying when we hit the
command *#mount -t nfs <serverIP>:/<path> /<mount point>* ,It will try to
mount with v2 & v3 but SSVM did not. I don't know why NFS is doing strange
behaviour on SSVM like this)

The existing SSVM was created using an old template recently .The old SSVM
which were created from the same template used to mount automatically
previously. I couldn't understand why the issue suddenly showed up for this
new SSVM.
Any thoughts on this.??

Also where can we find the scripts for auto mount on Cloud Stack, SSVM
scripts and Cloud-Stack scripts on XenServer ???


Thanks,
Anil.
