Re: [Xen-API] [SOLVED] NFS Share on localhost / same computer

[sentinel <sentinel2k01@xxxxxx>]

I found some older howto's with the same infos. Problem is, with Debian 
Wheezy (Testing) there is no portmap more. It is replaced by rpcbind.
So i looked after some howto's about rpcbind...

I changed the hosts.allow and hosts.deny

root@XenServer:/# cat /etc/hosts.allow
[---cut---]
mount.nfs rpc.mountd portmap rpcbind mountd nfsd statd lockd rquotad : 
192.168.0.0/255.255.255.0 , 127.0.0.1
root@XenServer:/# cat /etc/hosts.deny
[---cut---]
mount.nfs rpc.mountd portmap rpcbind mountd nfsd statd lockd rquotad :  ALL


after restarting the nfs and rpcbind services and try to create the new 
SR the following error
occured

Error code: SR_BACKEND_FAILURE_88
Error parameters: , NFS SR creation error [opterr=remote directory 
creation error is 13],
in the citrix forum i found an old entry from 2009, with the solution.
I have to add "no_root_squash" to the share entry in  /etc/exports and 
now it works!
Thank you to bring me into the right direction! :)
