From 4a65356275cda45f665dfa99d3712f6fb9087aff Mon Sep 17 00:00:00 2001 From: shishir gowda Date: Fri, 17 Feb 2012 19:21:07 +0530 Subject: cluster/dht: Support for hardlink rebalance when decommissioning The support for hardlink rebalance is only available for decommissioning of a node. this can be triggered in two ways 1. remove-brick start 2. if decommission node value is set in vol file, then a normal rebalance command The way we handle it is- if (nlink > 1) do * if src file doesnt have linkto xattr * mark src's linkto to the dst * else * perform a link on the dst * do a look up * if nlinks = dst.nlinks * migrate data * else * continue crawling done Signed-off-by: shishir gowda Change-Id: If43b5524b872fd1413e9f7aa7f436cb244e30d8d BUG: 763844 Reviewed-on: http://review.gluster.com/2737 Tested-by: Gluster Build System Reviewed-by: Amar Tumballi --- xlators/cluster/dht/src/dht.c | 1 + 1 file changed, 1 insertion(+) (limited to 'xlators/cluster/dht/src/dht.c') diff --git a/xlators/cluster/dht/src/dht.c b/xlators/cluster/dht/src/dht.c index 816bf868e88..bb6f8c09901 100644 --- a/xlators/cluster/dht/src/dht.c +++ b/xlators/cluster/dht/src/dht.c @@ -284,6 +284,7 @@ dht_parse_decommissioned_bricks (xlator_t *this, dht_conf_t *conf, } ret = 0; + conf->decommission_in_progress = 1; out: if (dup_brick) GF_FREE (dup_brick); -- cgit
