Re: [autofs] Simple direct mout problem

[Dana Wellen]

Ian,   Finally figured it out, simply put: auto.master /-      yp:auto.linux auto.linux /some_mount_directory/example                   server:/nfs_export works.  However if the yp map is changed to /example                  server:/nsf_export it fails.  The error in the messages file aren't very helpful in figuring this simple error out.  Will the next version (5) work more like the Sun automounter? I know in our case we are moving off of standard Unix to Linux due to support being dropped for our main platform (HP-UX) for our CAD software vendors. What I am seeing with indirect mounts and ghosting is that the only directories visible in the mount directory are directories that are mounted or been mounted but won't show the directories never mounted, examples: Before any mounts: ls -la /proj total 8 drwxr-xr-x   2 root root    0 Sep 27 14:02 . drwxr-xr-x  29 root root 4096 Sep 27 14:01 .. ls /proj/some_directory file1 file2 directory1 directory2 etc.. ls -la /proj total 12 drwxr-xr-x   3 root   root    0 Sep 27 14:03 . drwxr-xr-x  29 root   root 4096 Sep 27 14:01 .. drwxrwxr-x   9 root root  4096 Nov  3  2005 some_directory Well after the 60 second timeout ls -la /proj total 12 drwxr-xr-x   3 root   root    0 Sep 27 14:03 . drwxr-xr-x  29 root   root 4096 Sep 27 14:01 .. drwxrwxr-x   9 root root  4096 Nov  3  2005 some_directory This directory holds over 100 subdirectories that the user can't see and can only be accessed if they know the name of the subdirectory.

Update it. /etc/auto.master /- yp:auto.linux ypcat -k auto.linux /proj server2:/vol/proj/xx_proj Nop. There are an number of limitations with direct mounts in version 4. Single level direct mounts is one. This is documented in the readme file in /usr/share/doc/aufofs-4.1.3/README.direct When the autofs is started or restarted in the /var/log/messages I get : automount[25461]: cache_ghost: entry in yp:auto.linux not valid map format, key /proj If I use indirect mounts it works however direct mounts would be a lot easier for my users in that they will be able to see the directories in the mounted directory. The ghost function doesn't work well because it will only show the mounted directories or the directories that have been mounted since the last restart of the autofs. That's not correct. If I copy the file to the /etc directory it still has a similar error. Huh ???? aufofs-4.1.3/README.direct -- For example if we were using NIS we might have something like the map entries below. In the master map: /- autofs.global and in autofs.global: /nfs/apps/mozilla bogus:/usr/local/moxilla /nfs/data/budgets tiger:/usr/local/budgets /tst/sbin bogus:/usr/sbin and so on. Note that the RedHat package has a config entry that disables direct mounts by default because of the limitations. Change it if you wish to try using them (in /etc/sysconfig/autofs). Ian --
