Hi, I think I've found a bug in reiserfs acls. If triggered it means that any program trying to access the partition, where the bug occured, will just hang in D state, with no way to kill the program.
Here's how to reproduce: 1. mount a reiserfs volume (loopmount will do) with "-o acl". 2. create a directory "dir" 3. set some default acl: setfacl -d -m u:username:rwX dir 4. cd dir 5. dd if=/dev/zero of=somefile1 bs=4k count=100000 (the idea is to run out of space) 6. now df should show 0 free space, if not then repeat 5. 7. echo "1" > somefile2 # this should hang infinitely Now no program will be able to access the partition. I haven't tried to reproduce it, but the same problem also happened when a user hit his hard quota limit on my server. Then no program could access his homedir. PS.
