* ec : trusted.ec.version xattr of all root directories of all bricks should ↵Ashish Pandey2015-08-291-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | be same. Problem: After replacing the brick using "replace-brick" command and running "heal full", the version of the root directory of the newly added brick is not getting healed. heal starts running on the dentries of the root but does not run on root directory. Solution: Run heal on root directory. > Change-Id: Ifd42a3fb341b049c895817e892e5b484a5aa6f80 > BUG: 1243382 > Signed-off-by: Ashish Pandey <aspandey@redhat.com> > Reviewed-on: http://review.gluster.org/11676 > Reviewed-by: Pranith Kumar Karampuri <pkarampu@redhat.com> > Tested-by: NetBSD Build System <jenkins@build.gluster.org> Change-Id: Ifd42a3fb341b049c895817e892e5b484a5aa6f80 BUG: 1243384 Signed-off-by: Ashish Pandey <aspandey@redhat.com> Reviewed-on: http://review.gluster.org/11755 Tested-by: Gluster Build System <jenkins@build.gluster.com> Tested-by: NetBSD Build System <jenkins@build.gluster.org> Reviewed-by: Pranith Kumar Karampuri <pkarampu@redhat.com>

* cluster/ec: Change meaning of trusted.ec.dirtyPranith Kumar K2015-05-081-5/+9
| | | | | | | | | | | | | | | | | - With this change, the xattr will represent if the file needs to be healed or not. It will have different values for data/entry and metadata changes. - inode ref leaks and dict_set_dynstr related leaks fixed - Added support for trylock/lock based on heal-cmd execution or not in data heal. - Made fixes to pass regression runs Change-Id: I9d8def4c2badde18a76b7898816fecfac113737a BUG: 1216303 Signed-off-by: Pranith Kumar K <pkarampu@redhat.com> Reviewed-on: http://review.gluster.org/10385 Reviewed-on: http://review.gluster.org/10693 Tested-by: NetBSD Build System Tested-by: Gluster Build System <jenkins@build.gluster.com>
* libglusterfs/syncop: Add xdata to all syncop callsRaghavendra Talur2015-04-081-4/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds support for xdata in both the request and response path of syncops. Few calls like lookup already had the support; have renamed variables in few places to maintain uniformity. xdata passed downwards is known as xdata_in and xdata passed upwards is known as xdata_out. There is an old patch by Jeff Darcy at http://review.gluster.org/#/c/8769/3 which does the same for some selected calls. It also brings in xdata support at gfapi level. xdata support at gfapi level would be introduced in subsequent patches.

* Avoid conflict between contrib/uuid and system uuidEmmanuel Dreyfus2015-04-041-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | glusterfs relies on Linux uuid implementation, which API is incompatible with most other systems's uuid. As a result, libglusterfs has to embed contrib/uuid, which is the Linux implementation, on non Linux systems. This implementation is incompatible with systtem's built in, but the symbols have the same names. Usually this is not a problem because when we link with -lglusterfs, libc's symbols are trumped. However there is a problem when a program not linked with -lglusterfs will dlopen() glusterfs component. In such a case, libc's uuid implementation is already loaded in the calling program, and it will be used instead of libglusterfs's implementation, causing crashes. A possible workaround is to use pre-load libglusterfs in the calling program (using LD_PRELOAD on NetBSD for instance), but such a mechanism is not portable, nor is it flexible. A much better approach is to rename libglusterfs's uuid_* functions to gf_uuid_* to avoid any possible conflict. This is what this change attempts.

* cluster/ec: Add self-heal-daemon command handlersPranith Kumar K2015-03-091-0/+598
This patch introduces the changes required in ec xlator to handle index/full heal. Index healer threads: Ec xlator start an index healer thread per local brick. This thread keeps waking up every minute to check if there are any files to be healed based on the indices kept in index directory. Whenever child_up event comes, then also this index healer thread wakes up and crawls the indices and triggers heal. When self-heal-daemon is disabled on this particular volume then the healer thread keeps waiting until it is enabled again to perform heals. Full healer threads: Ec xlator starts a full healer thread for the local subvolume provided by glusterd to perform full crawl on the directory hierarchy to perform heals. Once the crawl completes the thread exits if no more full heals are issued. Changed xl-op prefix GF_AFR_OP to GF_SHD_OP to make it more generic.
