Inode numbers in isofs

[Ludovic Courtès]

Hi,

When running find on an isofs tree (findutils 4.1.7), we get this kind of
error messages:

  find: ./.. changed during execution of find

>From what I've seen in find, it issues this message if the inode number or
device number of a directory has changed during its execution. Looking at
isofs, I noticed two things. First, the st_dev field of struct stat is never
assigned (I think it should be equal to the server's pid). Moreover, the inode
number of "foo" appears to be different from the inode number of "foo/bar/.."
(I wrote a small test program for this, see attachment). This seems to be due
to the way it gets calculated in inode.c:read_disknode() :

  st->st_ino = (ino_t) ((void *) dr - (void *) disk_image);

However, I couldn't find how to get the parent's directory inode number from
there, so I decided to send a bug report instead. ;)

Hope this helps.
Cheers,
Ludovic.
