NFS Question.
I have a question about NFS and CentOS 6.0.
Here is the environment: Server running VMware's esxi 3.5 (Fully patched) 10.1.1.50 Server running CentOS 5.5 with NFS. 10.1.1.51 With the systems in the above config everything is working fine. Install a new hard drive in the CentOS server and install CentOS 6.0. Use the same IP 10.1.1.51. Configure NFS, the VM server can't attach to the NFS share. Here is the config of the NFS server: Firewall Disabled SELinux Disabled NFS installed and running. NFS-Utils installed. Contents of /etc/exports /fileshare 10.1.1.0/24 (rw,async,no_root_squash) /etc/hosts.allow is empty /etc/hosts.deny is empty Perms on /fileshare 755 rpcinfo -p 10.1.1.51 program vers proto port service 100000 4 tcp 111 portmapper 100000 3 tcp 111 portmapper 100000 2 tcp 111 portmapper 100000 4 udp 111 portmapper 100000 3 udp 111 portmapper 100000 2 udp 111 portmapper 100024 1 udp 51781 status 100024 1 tcp 33679 status 100011 1 udp 875 rquotad 100011 2 udp 875 rquotad 100011 1 tcp 875 rquotad 100011 2 tcp 875 rquotad 100003 2 tcp 2049 nfs 100003 3 tcp 2049 nfs 100003 4 tcp 2049 nfs 100227 2 tcp 2049 nfs_acl 100227 3 tcp 2049 nfs_acl 100003 2 udp 2049 nfs 100003 3 udp 2049 nfs 100003 4 udp 2049 nfs 100227 2 udp 2049 nfs_acl 100227 3 udp 2049 nfs_acl 100021 1 udp 41232 nlockmgr 100021 3 udp 41232 nlockmgr 100021 4 udp 41232 nlockmgr 100021 1 tcp 51294 nlockmgr 100021 3 tcp 51294 nlockmgr 100021 4 tcp 51294 nlockmgr 100005 1 udp 44019 mountd 100005 1 tcp 57834 mountd 100005 2 udp 44019 mountd 100005 2 tcp 57834 mountd 100005 3 udp 44019 mountd 100005 3 tcp 57834 mountd I have confirmed I can telnet to the ports listed. Any clue why the setup with CentOS 6.0 doesn't work? Is this a NFS4 vs. NFS3 thing? Is there a way to force CentOS to use NFS3? I am pretty sure the CentOS 5.5 server is using NFS4. I am at a loss and any help is appreciated. -Rap |
There's a good HOWTO etc here http://www.linuxtopia.org/online_boo...ion/index.html Chap 18. It mentions the differences in versions.
iirc, NFSv4 (amongst other things) has rpc.mountd & portmap functionality built in, so you don't need those daemons. It also goes into details about exportfs file maps 18.7.1.1. Using exportfs with NFSv4 |
After reading through section 18 of the link I did find a little new information but, it didn't help.
I learned my exports file need to be formatted this way: / *(ro,fsid=0) /backups 10.1.1.0/255.255.255.0(rw,async,no_root_squash,nohide) Any other Ideas? -Rap |
I found the issue, it was a ID10T error.
I needed to remove the old mount from the client and reestablish with the mount with the rebuild (CentOS 6) server. I did find that for whatever reason I could not us bit masks (/24) in my files I had to use subnet masks (255.255.255.0) to get the exports to work. -Rap |
