From 8210ca1a5c0e78e91c6fab7df7e002e39660b706 Mon Sep 17 00:00:00 2001 From: Ravishankar N Date: Sun, 10 Jan 2016 09:19:34 +0530 Subject: afr: Add throttled background client-side heals If a heal is needed after inode refresh (lookup, read_txn), launch it in the background instead of blocking the fop (that triggered refresh) until the heal happens. afr_replies_interpret() is modified such that the heal is launched only if atleast one sink brick is up. Max. no of heals that can happen in parallel is configurable via the 'background-self-heal-count' volume option. Any number greater than that is put in a wait queue whose length is configurable via 'heal-wait-queue-leng' volume option. If the wait queue is also full, further heals will be ignored. Default values: background-self-heal-count=8, heal-wait-queue-leng=128 Change-Id: I1d4a52814cdfd43d90591b6d2ad7b6219937ce70 BUG: 1297172 Signed-off-by: Ravishankar N Reviewed-on: http://review.gluster.org/13207 Smoke: Gluster Build System CentOS-regression: Gluster Build System Reviewed-by: Pranith Kumar Karampuri Tested-by: Pranith Kumar Karampuri NetBSD-regression: NetBSD Build System --- libglusterfs/src/globals.h | 4 ++++ 1 file changed, 4 insertions(+) (limited to 'libglusterfs/src') diff --git a/libglusterfs/src/globals.h b/libglusterfs/src/globals.h index ae05a3abd15..cd4582a12f8 100644 --- a/libglusterfs/src/globals.h +++ b/libglusterfs/src/globals.h @@ -62,6 +62,10 @@ #define GD_OP_VERSION_3_7_7 30707 /* Op-version for GlusterFS 3.7.7 */ +/* Op-version was not bumped up for 3.7.8 */ + +#define GD_OP_VERSION_3_7_9 30709 /* Op-version for GlusterFS 3.7.9 */ + #define GD_OP_VERSION_4_0_0 40000 /* Op-version for GlusterFS 4.0.0 */ #define GD_OP_VER_PERSISTENT_AFR_XATTRS GD_OP_VERSION_3_6_0 -- cgit
