The old value was too low and unnecessarily limited performance. - Update the drop_count for mounted fs's from the drop_count set through /proc/cluster/lock_dlm/drop_count, so the drop_count setting can be changed on a mounted fs. bz 218795 Patches: http://sourceware.org/cgi-bin/cvsweb.cgi/cluster/gfs-kernel/src/dlm/lock_dlm.h.diff?cvsroot=cluster&only_with_tag=STABLE&r1=1.18.2.3.6.2&r2=1.18.2.3.6.3 http://sourceware.org/cgi-bin/cvsweb.cgi/cluster/gfs-kernel/src/dlm/thread.c.diff?cvsroot=cluster&only_with_tag=STABLE&r1=1.16.2.3&r2=1.16.2.3.6.1 --- cluster/gfs-kernel/src/dlm/Attic/lock_dlm.h 2006/07/12 21:58:29 1.18.2.3.6.2 +++ cluster/gfs-kernel/src/dlm/Attic/lock_dlm.h 2006/12/08 17:27:44 1.18.2.3.6.3 @@ -46,7 +46,7 @@ #define LOCK_DLM_MAX_NODES (128) -#define DROP_LOCKS_COUNT (50000) +#define DROP_LOCKS_COUNT (200000) #define DROP_LOCKS_PERIOD (60) #define SHRINK_CACHE_COUNT (100) #define SHRINK_CACHE_MAX (1000) --- cluster/gfs-kernel/src/dlm/Attic/thread.c 2005/03/10 07:09:41 1.16.2.3 +++ cluster/gfs-kernel/src/dlm/Attic/thread.c 2006/12/08 17:27:44 1.16.2.3.6.1 @@ -13,6 +13,8 @@ #include "lock_dlm.h" +extern int lock_dlm_drop_count; + /* * Run in dlm_async thread */ @@ -292,6 +294,7 @@ if (check_timeout(dlm->drop_time, dlm->drop_locks_period)) { dlm->drop_time = jiffies; + dlm->drop_locks_count = lock_dlm_drop_count; if (atomic_read(&dlm->lock_count) >= dlm->drop_locks_count) return TRUE; }
