Description of problem:
have /tmp as a jfs filesystem. On rare occasions, when the backups run, too many
resource forks are opened or some other magic condition, and /tmp justs stops
Processes using /tmp hang and are unkillable, /tmp can't be unmounted cleanly,
sometimes even fails a sysrq sync and unmount.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
cd to a jfs mount point, run this script:
while /bin/true; do
echo $LOOP0 ":" $LOOP1
wait for the script to hang ... see if you can access that filesystem.
Actual Results: ran it on /tmp. It hung, required a reboot.
Expected Results: when I reformatted /tmp as ext2, it died cleanly when it
couldn't create any more directories.
