Hi,
Under FC4 I am trying to export a filesystem through NFS. The export
fails, however hard I try.
If I try to mount the (obviously unexported) FS from another machine, I
get the usual "reason given by server: Permission denied" message.
The question is how to debug this anomaly, namely that exportfs does
not do anything, and does not report any error.?
HEre is what I did:
-----------------
1 stop iptables
2 restart nfsd
3 Check NFS support in kernel:
zcat /proc/config.gz | grep NFS
CONFIG_NFS_FS=y
CONFIG_NFS_V3=y
# CONFIG_NFS_V3_ACL is not set
CONFIG_NFS_V4=y
CONFIG_NFS_DIRECTIO=y
CONFIG_NFSD=y
CONFIG_NFSD_V3=y
# CONFIG_NFSD_V3_ACL is not set
CONFIG_NFSD_V4=y
CONFIG_NFSD_TCP=y
CONFIG_NFS_COMMON=y
CONFIG_NCPFS_NFS_NS=y
4 "Check your /etc/exports file and make sure that the
volume is exported and that your client has the right kind
..."
Here is the entry from /etc/exports:
/mnt/md0 131.100.100.100(sync,no_subtree_check,rw)
5 "Make sure that you have told NFS to register any
changes you made to /etc/exports since starting nfsd by
running the exportfs command. Be sure to type exportfs -ra
to be extra certain that the exports are being re-read."
exportfs -rav
exportfs -ra
..
--> No output.
6. Check the file /proc/fs/nfs/exports and make sure the
cat /proc/fs/nfs/exports
# Version 1.1
# Path Client(Flags) # IPs
volume and client are listed correctly. (You can also look
at the file /var/lib/nfs/xtab for an unabridged list of how
cat /var/lib/nfs/xtab*
-> zero byte files.
all the active export options are set.) If they are not,
then you have not re-exported properly. If they are listed,
=> So what can I do if they are not properly exported?
Cheers
Gaspar
