Title: C6 nfs-utils problems
Post by: gerald_clark on May 05, 2015, 04:27:17 PM

showmount does not show any mounts.  Instead it errors.

showmount --exports vault
clnt_create: RPC: Unknown host

Ping of vault works.
showmount run on a CentOS 6 machine show the exports as expected.

nfs V4 errors
nfs4 mounting an export.  Mount succeeds, but an ls -l of any subdirectory of the mount point shows all files and directories have a user and
group of 42949672
"ls -ln" shows user and group of 4294967294
Files created by the Core 6 client show up on the server with the proper user and group, but show on Core as described above.
The directory is exported with no_root_squash and the default no_user_squash.
nfs4 mounts from a CentOS 6 machine show proper user and groups.

Do you think this is an nfs bug, something to do with the extension packaging or a tc base bug?

I really don't know. I just started using NFS4 on tc to get nfs connections through my firewall.
I tried 6.0 and 5.4 with the same results - odd 'ls -l' output for 'NFS4' and correct output for NFS3.
Since it seems to work except for the user and group i  'ls', I am wondering if it a busybox 'ls' bug.  Is there a different user and group id integer size in V4 vs V3?
Without another 'ls' program I cant check that out though.
Showmount not working suggests a busybox problem.

there's a "ls" in the coreutils extension, you could maybe try that?

coreutils.tcz provides the the standard ls command.

With /usr/local/bin/ls ls -l and ls -ln both show user and group as  4294967294.
It is starting to look like an nfs-utils problem.

ref blfs svn, is libnfsidmap required?

..or ref http://tinycorelinux.net/5.x/x86_64/tcz/src/nfs-utils/compile_nfs-utils is nfsv4 even enabled?

Hi gerald_clark
Don't know if it helps, but Googling  linux nfs user group 42949672  turned up this:

None of the files referenced in that article exist in /etc or /usr/local/etc in tc
Also, tc has no idmapd program.
