If you have to share those partitions via AFP, you are lost at the moment. Apple violates their own specs when the sharepoints are on UFS. And there are also differences in handling files from CLI and from within Finder! Example 1) You are not able to store Finder comments on UFS partitions when doing it via AFP Example 2) Saving a file from a client mac will lead to wrong ownerships (wrong owner for the resource fork and wrong group for both) and 'funky' permissions: drwxrwx--- 4 tk wheel 1024 Dec 11 08:52 . -rw-r--r-- 1 root staff 61208 Dec 11 08:52 ._05_18_medium.JPG -rw-r--r-- 1 tk staff 4048652 Dec 11 08:52 05_18_medium.JPG Example 3) When copying this file: drwxrws--- 20 tk staff 2048 Dec 11 08:30 . -rw-rw-r-- 1 tk staff 8050 Nov 25 00:23 ._05_18_medium.JPG -rw-rw-r-- 1 tk staff 4042299 Nov 25 00:23 05_18_medium.JPG from one location to another you get - maybe correct permissions (honoring umask?) and ownerships (is it legal to change the group?) but wrong timestamps when doing it locally from the Finder drwxrwx--- 2 tk wheel 1024 Dec 11 08:48 . -rw-rw-r-- 1 tk wheel 8050 Dec 11 08:48 ._05_18_medium.JPG -rw-rw-r-- 1 tk wheel 4042299 Nov 25 00:23 05_18_medium.JPG - correct permissions (honoring AFP stuff) and timestamps but wrong ownerships when doing via AFP drwxrwx--- 4 tk wheel 1024 Dec 11 08:46 . -rw-rw---- 1 root wheel 8050 Dec 11 08:46 ._05_18_medium.JPG -rw-rw---- 1 tk wheel 4042299 Dec 11 08:46 05_18_medium.JPG - funny results when doing it with /Developer/Tools/CpMac (look at the group permissions of data- and resourcefork ;-) drwxrws--- 4 tk wheel 1024 Dec 11 09:17 . -rw-r--r-- 1 root wheel 8050 Dec 11 09:17 ._05_18_medium.JPG -rw-rw-r-- 1 root wheel 4042299 Dec 11 09:17 05_18_medium.JPG - different results when doing it with ditto (preserving timestamps) drwxrws--- 4 tk wheel 1024 Dec 11 09:19 . -rw-rw-r-- 1 tk staff 8050 Nov 25 00:23 ._05_18_medium.JPG -rw-rw-r-- 1 tk staff 4042299 Nov 25 00:23 05_18_medium.JPG - also different results when doing it with cp: drwxrws--- 4 tk wheel 1024 Dec 11 09:19 . -rw-rw-r-- 1 tk staff 8050 Dec 11 09:20 ._05_18_medium.JPG -rw-rw-r-- 1 tk staff 4042299 Dec 11 09:20 05_18_medium.JPG Example 4) Lack of support for file-/folder-IDs or better: wrong calculation scheme for those instead of maintaining a persistent database: If you open a SimpleText document from a client Mac and move the file inside the share while still open, the next attempt to save this file will result in a droppend AFP-connection and an error message (note: with AFP it's quite legal to move/rename open files as they are to be found by id not by name or path). When using Quark Xpress you will also loose your document itself as you won't be able to save it any more if opened directly from the server. There are some other minor problems too... but to hit the spot: You have to decide: - using a filesystem that is known to commit suicide from time to time by itself: HFS+ - using a filesystem that is more stable but quite unusable for serious file handling due to limitations in Apple's implementations (*always* different results when doing it via AFP, from the finder or the various CLI-tools): UFS It's not the problem with UFS itself. I'm using a third-party AFP-stack (still called beta) and have no problems when sharing UFS (what Helios recommends).
