Hi,

I'm using autofs to automount the home dirs of my users, distributed among
several machines. The config files are:

***** /etc/auto.master: *****
/home /etc/auto_home
***** end /etc/auto.master *****

***** /etc/auto_home: *****
canalias        -rsize=8192,wsize=8192  e04:/homes/&
jmbenita        -rsize=8192,wsize=8192  e05:/homes/&
...
***** end /etc/auto_home *****

Until now, it was all working fine. A few days ago I moved the directory
e04:/homes from / to a (larger) partition, which I now mount as /homes:

***** /etc/fstab: *****
# /etc/fstab: static file system information.
#
#<file sys>          <mount point>     <type>   <options>   <dump>   <pass>
/dev/sda3    /                 ext3    rw,errors=remount-ro  0    1
/dev/sda2    none              swap    rw        0    0
none         /proc             proc    defaults  0    0
none  /proc/bus/usb  usbdevfs  defaults
/dev/fd0  /floppy  auto  users,noauto 0 0
/dev/sda5    /usr                 ext3    defaults  0    2
/dev/sda6    /homes                 ext3    defaults  0    2
***** end /etc/fstab *****

Since that moment, I am having problems accessing anything below /home. For
instance, I can't do

	ls /home

because the shell hangs. It just becomes irresponsive.

There are currently Condor processes running with working directory
/home/canalias.

I've been trying to find out what's going on, with no luck for the moment. Any
hint would be greatly appreciated. I don't even know where to look for logged
errors from the automounter.

I next list the output of command "mount" and "autofs status" for reference:

eixam:~# mount
/dev/sda3 on / type ext3 (rw,errors=remount-ro)
proc on /proc type proc (rw)
sysfs on /sys type sysfs (rw)
devpts on /dev/pts type devpts (rw,gid=5,mode=620)

e05:/homes/jmbenita on /home/jmbenita type nfs

eixam:~# /etc/init.d/autofs status

Thanks a lot,
