Problem in NFS file system mounting
?------------ ? ? ? ? ? SharedFolder
Also, before the problem occurrence all the created files owner were root:root, now the ownership of newly created files are nobody:nobody. The Operating system of both clients and server are RHEL4-64bit.
Remounting the partition solves the problem temporarily but it happens again within an hour. The result of NFS debug process are as follow:
Client
Mar 9 12:17:04 app4 kernel: NFS: revalidating (0:13/2)
Mar 9 12:17:04 app4 kernel: NFS call getattr
Mar 9 12:17:04 app4 kernel: NFS reply getattr
Mar 9 12:17:04 app4 kernel: nfs_revalidate_inode: (0:13/2) getattr failed, error=-13
Server

Re: Problem in NFS file system mounting
x.x.x.x:/SharedFolder /SharedFolder nfs remount,rw,hard,nointr,tcp,vers=3,timeo=300,rsize= 32768,wsize=32768,actimeo=0 0 0
The output of mount command when the problem happens:
x.x.x.x:/SharedFolder /SharedFolder type nfs (rw,hard,nointr,nfsvers=3,tcp,timeo=300,rsize=3276 8,wsize=32768,actimeo=0,addr=x.x.x.x)
This the content of /etc/exports
/SharedFolder app*.domainname(rw)
/SharedFolder x.x.x*(rw)

Re: Problem in NFS file system mounting
Now since earlier permission used to be root:root that mean only root can change the permissions so you would like to see if any command/script.
You may also would like to check if there is any sequence for permission change.
