Description David Teigland 2006-12-07 15:57:58 UTC
Description of problem:

The default lock_dlm drop_locks value is 50,000 locks which is
probably too low -- we end up telling a lot of people to increase
(or disable) it.  I think we should change the default to something
like 200,000.

You can change the drop_count by echo'ing a new value into
/proc/cluster/lock_dlm/drop_count, but it only takes effect for
the fs's when they're mounted.  It would be simple to make it
take effect for currently mounted fs's so people could change
it online for fs's without remounting them.
