Re: [Users] (potential bug) After I create a virtual disk I am unable to start a VM - Permissions issue ? The node seems to have no write access to the directory on the NFS server...

Hi. My setup is 3 servers 1. Frontend (engine). 2 Ovirt node 3. Nfs server (debian) From the Frontend (engine) :- -bash-4.2$ ls -la /tmp/test/2f7ee7bc-09b3-42ba-af91-40d79293e360/images/d1fcc1ae-dcf5-426e-a99f-3a48e84c5ae3/ total 2097168 drwxr-xr-x. 2 vdsm kvm 4096 Mar 28 2012 . drwxr-xr-x. 3 vdsm kvm 4096 Mar 28 2012 .. -rw-rw----. 1 vdsm kvm 2147483648 Mar 28 2012 9fe193c9-7139-4a6c-933a-c6f31d5e96bd -rw-r--r--. 1 vdsm kvm 317 Mar 28 2012 9fe193c9-7139-4a6c-933a-c6f31d5e96bd.meta I have (now) write access with vdsm user from here From the node (look at ownership....) :- -bash-4.2$ ls -la /rhev/data-center/b2b2e054-66b2-11e1-bda3-1728f784de9e/2f7ee7bc-09b3-42ba-af91-40d79293e360/images/d1fcc1ae-dcf5-426e-a99f-3a48e84c5ae3/ total 2097168 drwxr-xr-x. 2 4294967294 4294967294 4096 Mar 28 13:21 . drwxr-xr-x. 3 4294967294 4294967294 4096 Mar 28 13:05 .. -rw-rw----. 1 4294967294 4294967294 2147483648 Mar 28 13:05 9fe193c9-7139-4a6c-933a-c6f31d5e96bd -rw-r--r--. 1 4294967294 4294967294 317 Mar 28 13:05 9fe193c9-7139-4a6c-933a-c6f31d5e96bd.meta

Also From the engine - mount command:- 10.0.0.190:/storage1/ on /tmp/test type nfs (rw,relatime,vers=3,rsize=1048576,wsize=1048576,namlen=255,hard,proto=tcp,timeo=600,retrans=2,sec=sys,mountaddr=10.0.0.190,mountvers=3,mountport=35065,mountproto=udp,local_lock=none,addr=10.0.0.190) - note that the NFS share wasn't mounted until I mounted it... From the node - mount command 10.0.0.190:/storage1/ on /rhev/data-center/mnt/10.0.0.190:_storage1 type nfs4 (rw,relatime,vers=4,rsize=1048576,wsize=1048576,namlen=255,soft,nosharecache,proto=tcp,port=0,timeo=600,retrans=6,sec=sys,clientaddr=10.0.0.101,minorversion=0,local_lock=none,addr=10.0.0.190) - looks like nfs4 on the node........ Any ideas anyone ?
