This section describes how to mount and export via NFS a cdrom drive.
Mount the cdrom. If you encounter a problem with your cdrom drive,
read the CDROM-HOWTO. I assume that the cdrom
device is /dev/hdd but it could be /dev/sr0 or
/dev/hdb etc. The mount point I choose is /cdrom
but you can choose the one you want:
$ mount -t iso9660 /dev/hdd /cdrom
You have to set up nfs services. If something goes wrong, read the
NFS-HOWTO
Verify your kernel supports nfs:
$ cat /proc/filesystems
ext2
nodev proc
nodev nfs
nodev ncpfs
nodev devpts
iso9660
Verify your portmapper can handle mountd and nfs client requests:
$ rpcinfo -p
program vers proto port
100000 2 tcp 111 portmapper
100000 2 udp 111 portmapper
100005 1 udp 655 mountd
100005 1 tcp 657 mountd
100003 2 udp 2049 nfs
100003 2 tcp 2049 nfs
Lines with nfs or portmapper have to be there. We
have NFS on tcp? progress have been made!
It doesn't matter if you have only NFS on udp. NFS has to work,
that's the thing you need.
Then, rerun portmap , mountd , nfs :
$ /etc/rc.d/init.d/portmap.init stop
Stopping INET services: portmap
$ /etc/rc.d/init.d/portmap.init start
Starting portmapper: portmap
$ /etc/rc.d/init.d/nfs stop
Shutting down NFS services: rpc.mountd rpc.nfsd
$ /etc/rc.d/init.d/nfs start
Starting NFS services: rpc.mountd rpc.nfsd
/etc/rc.d/init.d/ is /sbin/init.d/ on SuSE Linux
systems. I had a dream last night: LSB was respected. (LDB: Linux
Standard Base)
Then, try to mount it "locally" (via nfs) on the source box
and when the test is good remove the test directory:
$ mkdir /tmp/nfstest
$ mount -t nfs source:/cdrom /tmp/nfstest
$ ls /tmp/nfstest/
README debian/ locatedb.3 tools/
TRANS.TBL ftp.netscape.com/ ls_lR.3 upgrade/
boot/ install/ realaudio/
$ echo great stuff !
$ umount /tmp/nfstest
$ rmdir /tmp/nfstest
Bad luck ? Read the NFS-HOWTO and
/var/log/messages .
Check the nfs server with those commands:
$ rpcinfo -p
Run portmap with the -v flag:
$ portmap -v
kill portmap , mountd , nfsd and rerun them
in this order: portmap , mountd , nfsd .
Take a rest, get more coffee. Read again the
NFS-HOWTO and restart.
Now, the exported cdrom drive nfs server is ready to work.
Congratulations.
