[Ocfs2-users] global_bitmap lock busy for a long time

I am often experiencing long delays on ocfs2 volumes when another
process is writing to the fs. The delays seem to coincide with a busy
lock on //global_bitmap. I can understand why a busy lock on the
global_bitmap would cause delays (especially write delays), but it seems
to block reads too? Also, the lock seems to be held for quite a long
time at times, probably over a minute. This is on a 3TB fs that is 80%
full. This is a real problem for me because nfs mounts fail and then
give stale NFS handle even after the volume is free again. Is there a
way to improve the length of time the global_bitmap is locked?
Thanks,
Andy
