REVIEW: http://review.gluster.org/14065 (dht: add "nuke" functionality for efficient server-side deletion) posted (#1) for review on release-3.7 by Jeff Darcy (jdarcy) COMMIT: http://review.gluster.org/14065 committed in release-3.7 by Raghavendra G (rgowdapp) ------ commit 7241756f94c975c89f6dc1023d2403f531e6f5ac Author: Jeff Darcy <jdarcy> Date: Mon Apr 25 12:17:12 2016 -0400 dht: add "nuke" functionality for efficient server-side deletion This is a backport of the following two patches (of which the second is a trivial adjustment to a timeout for a test added by the first). http://review.gluster.org/13878 http://review.gluster.org/13935 This turns a special xattr into an rmdir with flags set. When that hits the posix translator on the server side, that causes the file/directory to be moved into the special "landfill" directory. From there, the posix janitor thread will take care of deleting it entirely on the server side - traversing it recursively if necessary. A couple of secondary issues were fixed to make this effective. * FUSE now ensures that setxattr values are NUL terminated. * The janitor thread now gets woken up immediately when something is placed in 'landfill' instead of only when file descriptors need to be closed. * The default landfill-emptying interval was reduced to 10s. To use the feature, issue a setxattr something like this: setfattr -n glusterfs.dht.nuke -v "" /mnt/glusterfs/vol/some_dir The value doesn't actually matter; the mere receipt of a request with this key is sufficient. Some day it might be useful to allow setting a required value as a sort of password, so that only those who know it can access the underlying special functionality.
