Hi
I moved my home directories onto a software RAID5 array, and from this
time on, Mozilla refused to start.
Since I had some similar problems with pgp and StarOffice which turned
out to be lock problems on NFS, I also suspected a lock problem here.
First, I tried to move to home directory onto a "normal" (ie. non-RAID
hosted) directory, and Mozilla worked.
Then I wrote a short program, which tests the lockf () function:
#include <sys/types.h>
#include <sys/stat.h>
#include <fcntl.h>
#include <sys/file.h>
#include <errno.h>
#include <stdio.h>
int main (int argc, char * argv [])
{
int f, st;
if (argc < 2) exit (1);
f = open (argv[1], O_RDWR);
st = lockf (f, F_LOCK, 1);
if (st) {
fprintf (stderr, "Error %d: ", errno);
perror ("flock");
exit (1);
}
exit (0);
}
Executed on a file in a RAID directory, it returned
Error 37: flock: No locks available
On files in non-RAID-directories it worked without error.
So, I come to the conclusion, that the RAID system does not support
locks, or the lock support is buggy.
The RAID hosts a ReiserFS. The kernel info is as follows:
