nfs: server totan OK
The last line indicates that there is a temporary problem in the NFS server
totan. The lines up to that point are triggered by the insertion of a USB
memory stick.
Older events are logged in the files /var/log/messages and /var/log/
warn.
28.10 File Systems and Their Usage:
mount, df, and du
The command mount shows which file system (device and type) is
mounted at which mount point:
$ mount
/dev/hdb2 on / type ext2 (rw)
proc on /proc type proc (rw)
devpts on /dev/pts type devpts (rw,mode=0620,gid=5)
/dev/hda1 on /data type ext2 (rw)
shmfs on /dev/shm type shm (rw)
usbdevfs on /proc/bus/usb type usbdevfs (rw)
automount(pid1012) on /suse type autofs \
(rw,fd=5,pgrp=1012,minproto=2,maxproto=3)
totan:/real-home/jj on /suse/jj type nfs \
(rw,nosuid,rsize=8192,wsize=8192,hard,intr,nolock,addr=10.10.0.1)
Obtain information about total usage of the file systems with the command
df. The parameter -h (or --human-readable) transforms the output into
a form understandable for common users.
$ df -h
