When mounting a NFS share on Ubuntu (and probably Debian) for the first time the following error can appear:
benyg@host:/mnt$ sudo mount -t nfs 10.x.x.x:/vol/vol1/rrd /mnt/rrd
mount: wrong fs type, bad option, bad superblock on 10.x.x.x:/vol/vol1/rrd,
missing codepage or helper program, or other error
(for several filesystems (e.g. nfs, cifs) you might
need a /sbin/mount.<type> helper program)
In some cases useful info is found in syslog - try
dmesg | tail or so
NFS Utilities
This usually occurs occurs because the nfs-common package needs to be installed:
- Debian / Ubuntu
sudo apt-get install nfs-common - Redhat/CentOS/Fedora
sudo yum install nfs-common - Mandriva
urpmi nfs-common - Gentoo
emerge nfs-common
- Depending on distro
nfs-utilsandnfs-utils-libmay also need to be installed.
Portmap
Ensure portmap is running:
[benyg@host:~] $ rpcinfo -p
program vers proto port service
100000 4 tcp 111 portmapper
100000 3 tcp 111 portmapper
100000 2 tcp 111 portmapper
100000 4 udp 111 portmapper
100000 3 udp 111 portmapper
100000 2 udp 111 portmapper
100000 4 0 111 portmapper
100000 3 0 111 portmapper
100000 2 0 111 portmapper
100024 1 udp 57055 status
100024 1 tcp 51056 status
Output if it is not running:
[benyg@host:~] $ rpcinfo -p
rpcinfo: can't contact portmapper: RPC: Remote system error - No such file or directory
- Install it through the
rpcbindpackage and start it.
