Re: [K12OSN] NFS fails to start



Hi,

I also tried to mount /opt/ltsp shared on the new server on the old server, just to test the share, so doing
mount -t nfs 192.168.0.1:/opt/ltsp /mnt/test/

I get these four rows of text in the new servers /var/log/messages:
May 2 07:37:00 ltsp rpc.mountd[2186]: authenticated mount request from 192.168.0.11:978 for /opt/ltsp (/opt/ltsp) May 2 07:37:00 ltsp rpc.mountd[2186]: qword_eol: fflush failed: errno 22 (Invalid argument) May 2 07:37:00 ltsp rpc.mountd[2186]: qword_eol: fflush failed: errno 2 (No such file or directory) May 2 07:37:00 ltsp rpc.mountd[2186]: Cannot export /opt/ltsp, possibly unsupported filesystem or fsid= required


> check contents of /etc/auto.misc for /opt/ltsp. Comment it out if found

don't have any files called /etc/auto.misc

> lsmod | grep nfs

nfsd                  304962  11
lockd                  73534  1 nfsd

sunrpc                261299  17 nfsd,lockd,nfs_acl,auth_rpcgss

Looks to me OK?

Looking at these lines I can't see any problems.


Kenneth


and see where ltsp is referenced.

Also do a


and make sure the you get something like:
nfsd                  274672  13
auth_rpcgss            48594  1 nfsd
nfs_acl                12741  1 nfsd
lockd                  93540  1 nfsd
sunrpc                256499  29 nfsd,auth_rpcgss,lockd,nfs_acl


If no nfsd, then BINGO! Just run modprobe nfsd and service nfsd restart
