I'm attempting to use autofs on some diskless machines which operate using an NFS mounted root file system. I have three different computers which share the same root file system (with unique /tmp and /var directories) and the same 2.6.22 kernel.
I want to use autofs for removable USB memory sticks. On one machine, I can use autofs just fine. Autofs mounts and unmounts the usb sticks as I expect it to. Works nice. However, on the other two machines, I cannot get automount to start. It simply hangs upon startup, I cannot ^C to exit or anything. I have to kill -9 the process. I cannot figure out what automount is looking for, and not getting, which would cause it to hang. I've attempted to use gdb to help me find the problem, but I haven't had much luck. (I've downloaded the most recent 5.0.2 tar bar and build automount with -g to debug. I'm hoping someone might shed some light on how best to debug this issue. On the two machines which fail, I see this message appear on the NFS server which is serving up the root file system. Dec 31 16:05:50 linux mountd[2130]: authenticated unmount request from asterisk:621 for /tftpboot/muekow/i386 (/tftpboot/muekow) I don't see any such message on the machine which works properly (the only clue I currently have). On the diskless machines, I have these mount points already defined before I attempt to start automount. 192.168.1.254:/tftpboot/muekow/i386 on /nfsroot type nfs (rw,vers=3,rsize=32768,wsize=32768,hard,nolock,proto=udp,timeo=7,retrans=3,sec=sys,addr=192.168.1.254) none on /proc type proc (rw) none on /dev type tmpfs (rw) /sys on /sys type sysfs (rw) none on /proc/bus/usb type usbfs (rw) 192.168.1.254:/home on /home type nfs (rw,vers=3,rsize=32768,wsize=32768,hard,nolock,proto=udp,timeo=7,retrans=3,sec=sys,addr=192.168.1.254) 192.168.1.254:/media on /media type nfs (rw,vers=3,rsize=32768,wsize=32768,hard,nolock,proto=udp,timeo=7,retrans=3,sec=sys,addr=192.168.1.254) Does automount for any reason attempt to unmount nfs mount points which are already in place? Thanks for any advice, I'm really stumped as to why automount won't start.
