- Help!
-
- I'm using an Iris4D running IRIX4.0.5 as an NFS server for MacIIfx running
- A/UX 3.0. I have had several problems, probably related.
-
- Initially, the problem was that setfile created a core dump when I tried
- to typify a file residing on the Iris disk. The file had no %... fork
- prior to setfile, and setfile was unable to create one. THis problem did
- not occur always, but about 50% of the time. Later, the problem got worse,
- it started to generate kernel panics. The tex was something like 'kmem:
- alloc'.
-
- Then I found the following fixup. I had put myself to group 'bin' in A/UX,
- in order to easily install new software to root partition without logging
- in as root. I changed this to 'other', and ensured it was the same group ID
- number as in Iris. I also realized that it was not necessary to use setfile,
- (which still tended to crash, one time even kernel panic), one could simply
- copy any correct-type %.. fork under the proper name. In this way, the
- typify operation could be performed on the Iris alone.
-
- However, yesterday I got a kernel panic when I just tried to save a file
- from Spyglass Transform (a regular Macintosh application) on NFS-mounted
- volume. It was 'kmem: alloc' again.
-
- What's going on? Do others experience similar problems with NFS? The bug
- is not easily repeatable (well, at least I dont want to repeat it). Is
- the agreement between NFS server/client group-ID's essential?
-
- Spyglass Transform had written part (16384 bytes) of the data fork before
- the crash. No %.. fork appeared. THe curious thing is that when I look the
- file from the Finder, it reports zero bytes size, still the ls -l from
- either A/UX or Iris shows 16384 bytes.
