[ovirt-users] nfs storage permission problem

[Bill James]

[vdsm at ovirt4 test /]$ touch 
/rhev/data-center/mnt/ovirt3-ks.test.j2noc.com:_ovirt-store_nfs/test
touch: cannot touch 
‘/rhev/data-center/mnt/ovirt3-ks.test.j2noc.com:_ovirt-store_nfs/test’: 
Read-only file system

Hmm, read-only.  :-(

ovirt3-ks.test.j2noc.com:/ovirt-store/nfs on 
/rhev/data-center/mnt/ovirt3-ks.test.j2noc.com:_ovirt-store_nfs type 
nfs4 
(*rw*,relatime,vers=4.0,rsize=1048576,wsize=1048576,namlen=255,soft,nosharecache,proto=tcp,port=0,timeo=600,retrans=6,sec=sys,clientaddr=10.100.108.96,local_lock=none,addr=10.100.108.33)

now to figure out why....


[root at ovirt4 test ~]# ls -la /rhev/data-center/mnt/
total 8
drwxr-xr-x 4 vdsm kvm  110 Apr 13 15:30 .
drwxr-xr-x 3 vdsm kvm   16 Apr 13 08:06 ..
drwxr-xr-x 3 vdsm kvm 4096 Mar 11 15:19 
netappqa3:_vol_cloud__images_ovirt__QA__export
drwxr-xr-x 3 vdsm kvm 4096 Mar 11 15:17 
netappqa3:_vol_cloud__images_ovirt__QA__ISOs



export and ISO domain mount fine too. (and rw)
