Hello all. I converted my server from Fedora Core 3 to CentOS 4.1 and I've
been slogging unsuccessfully through an NFSv4 problem. I'm using the same
configuration for NFS that I had in place on FC3 that worked. On the server,
I have the following data structure:
/data
/data/archive
/data/pictures
/data/music
Each is a separate ext3 filesystem mounted with rw,acl. /etc/exports presents
all of these filesystems properly:
# exportfs -v
/data/pictures 172.17.17.0/27
(rw,wdelay,insecure,root_squash,no_subtree_check,anonuid=65534,anongid=65534)
/data/archive 172.17.17.0/27
(rw,wdelay,insecure,root_squash,no_subtree_check,anonuid=65534,anongid=65534)
/data/music 172.17.17.0/27
(rw,wdelay,insecure,root_squash,no_subtree_check,anonuid=65534,anongid=65534)
/data 172.17.17.0/27
(rw,wdelay,insecure,root_squash,no_subtree_check,fsid=0,anonuid=65534,anongid=65534)
All the the appropriate services are running (portmap, nfs, rpcidmapd). I've
tried this with and without iptables enabled so I've ruled out firewall
issues. When I mount the filesystem on the client, none of the "sub"
mountpoints shows its content:
# mount -t nfs4 server:/ /mnt/server
# ls /mnt/server
archive lost+found music pictures
# ls /mnt/server/archive
#
Except that there's 15G of data in /data/archive on the server. File
operations in /data that don't traverse the server-side mountpoints work fine
(i.e. I've created /data/foo and performed reads and writes in there on the
client). I know that this setup worked in Fedora 3 so I'm unable to account
for the operational differences. Anyone have any thoughts?
