  | |  | NFS mount problem | NFS mount problem 2005-06-28 - By Magee, Fred (MRC)
Back Good morning. I have a clustered system where I nfs mount /home from the head node and /home/localscratch also from the head node. These two file systems are on separate drives on the head node. Everything was working until one node crashed for still mysterious reasons. Since that crash I cannot mount /home. I get: Jun 28 08:09:17 node1 rpc.mountd: authenticated mount request from node3.cl.mrcabq.com:935 for /home (/home) Jun 28 08:09:17 node1 rpc.mountd: getfh failed: Operation not permitted /etc/exports has: /home 10.0.0.2/10(rw,sync) /home/localscratch 10.0.0.2/10(rw,sync,no_root_squash) /usr/local 10.0.0.2/10(rw,sync,no_root_squash) /usr/ks 10.0.0.2/10(ro,sync,no_root_squash) /home/ks 10.0.0.2/30(ro,sync,no_root_squash) I can mount all file systems except /home. I have manually umounted /home/localscratch and attempted to mount /home with the same error. I have commented out /home/localscratch and rebooted node3 but still cannot mount /home. I've been working with RedHat support for three days now with no resolution. Does anyone out there have any suggestions. Thanks and have a great day. Fred
