Testing if a file system can be used for home directories...

2010-08-08 21:20

A few years ago, I was involved in a project planning to use -Windows file servers as home directory servers for Debian -Edu/Skolelinux machines. This was thought to be no problem, as the -access would be through the SMB network file system protocol, and we -knew other sites used SMB with unix and samba as the file server to -mount home directories without any problems. But, after months of -struggling, we had to conclude that our goal was impossible.

- -

The reason is simply that while SMB can be used for home -directories when the file server is Samba running on Unix, this only -work because of Samba have some extensions and the fact that the -underlying file system is a unix file system. When using a Windows -file server, the underlying file system do not have POSIX semantics, -and several programs will fail if the users home directory where they -want to store their configuration lack POSIX semantics.

- -

As part of this work, I wrote a small C program I want to share -with you all, to replicate a few of the problematic applications (like -OpenOffice.org and GCompris) and see if the file system was working as -it should. If you find yourself in spooky file system land, it might -help you find your way out again. This is the fs-test.c source:

When everything is working, it should print something like -this:

- -

-Testing POSIX/Unix sematics on file system
-info: testing symlink creation
-info: testing subdirectory creation
-info: sqlite worked
-info: testing fcntl locking
-  Read-locking 1 byte from 1073741824

-  Write-locking 510 byte from 1073741826
-  Unlocking 2 byte from 1073741824
-

- -

I do not remember the exact details of the problems we saw, but one -of them was with locking, where if I remember correctly, POSIX allow a -read-only lock to be upgraded to a read-write lock without unlocking -the read-only lock (while Windows do not). Another was a bug in the -CIFS/SMB client implementation in the Linux kernel where directory -meta information would be wrong for a fraction of a second, making -OpenOffice.org fail to create its deep directory tree because it was -not allowed to create files in its freshly created directory.

- -

Anyway, here is a nice tool for your tool box, might you never need -it. :)
