Description of problem: The documentation for this is: "Specifies the percentage of disk space that must be kept free. Might be useful for non-uniform bricks." It remains unclear what happens if less disk space is free. If there are no consequences then what's the point of having this? Version-Release number of selected component (if applicable): 3.3
Thanks for pointing this out.. We recently fixed this in upstream, and haven't yet backported to 3.3.x branch. The release-3.4 series will have the right fix. -Amar ----- commit 2f60c8a4776a6052cfba43605263dd32c616cfa2 Author: Avra Sengupta <asengupt> Date: Thu Jan 17 14:46:30 2013 +0530 glusterd/cli: Updated the options descriptions for "volume set help" Change-Id: I0db00b7334bb9707ab48bd661ac03a3ad818d6e4 BUG: 893458 Signed-off-by: Avra Sengupta <asengupt> Reviewed-on: http://review.gluster.org/4393 Tested-by: Gluster Build System <jenkins.com> Reviewed-by: Anand Avati <avati> diff --git a/xlators/cluster/dht/src/dht.c b/xlators/cluster/dht/src/dht.c index d70d713..bb4d70e 100644 --- a/xlators/cluster/dht/src/dht.c +++ b/xlators/cluster/dht/src/dht.c @@ -578,18 +578,23 @@ struct volume_options options[] = { "on", "off"}, .type = GF_OPTION_TYPE_STR, .default_value = "on", + .description = "This option if set to ON, does a lookup through " + "all the sub-volumes, in case a lookup didn't return any result " + "from the hash subvolume.
