* dht: do not remove linkfile if file exist in cached sub volumeVijaykumar M2014-02-021-19/+109
| | | | | | | | | | | | | | | | Currently with rmdir, if a directory contains only the linkfiles we remove all the linkfiles and this is causing the problem when the cached sub volume is down and end-up with duplicate files showing on the mount point. Solution: Before removing a linkfile check if the files exists in cached subvolume.

* cluster/afr: Add gfid to index in wind un-conditionallyPranith Kumar K2014-01-291-9/+25
| | | | | | | | | | | | | | | | | | | | | | | Problem: If brick crashes just after performing xattrop before reaching index _cbk then the gfid will not be added to/deleted from index. If it is not deleted it will be deleted when self-heal is triggered. But if the crash happens before the file is added to index, user may think the system does not need self-heal even when there is this file that needs to be healed. Fix: Add file to index un-conditionally in wind phase. This way the file remains in index even when brick process crashes before reaching _cbk. This does not affect performance because of caching(check _index_action) built into index xlator.

Even if the size attribute is not used (yet), it should be set correctly to prevent confusing while debugging network traffic with Wireshark or other tools. Note that the on-wire format is not being changed with this patch. The size is already part of the structure that is exchanged between the client and server.

* build: Start using library versioning for various librariesHarshavardhana2014-01-181-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | According to libtool three individual numbers stand for CURRENT:REVISION:AGE, or C:R:A for short. The libtool script typically tacks these three numbers onto the end of the name of the .so file it creates. The formula for calculating the file numbers on Linux and Solaris is /path/to/library/<library_name>.(C - A).(A).(R) As you release new versions of your library, you will update the library's C:R:A. Although the rules for changing these version numbers can quickly become confusing, a few simple tips should help keep you on track. The libtool documentation goes into greater depth. In essence, every time you make a change to the library and release it, the C:R:A should change. A new library should start with 0:0:0. Each time you change the public interface (i.e., your installed header files), you should increment the CURRENT number. This is called your interface number. The main use of this interface number is to tag successive revisions of your API. The AGE number is how many consecutive versions of the API the current implementation supports. Thus if the CURRENT library API is the sixth published version of the interface and it is also binary compatible with the fourth and fifth versions (i.e., the last two), the C:R:A might be 6:0:2. When you break binary compatibility, you need to set AGE to 0 and of course increment CURRENT. The REVISION marks a change in the source code of the library that doesn't affect the interface-for example, a minor bug fix. Anytime you increment CURRENT, you should set REVISION back to 0.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Quota and marker uses 'trusted.glusterfs.quota*' and 'trusted.pgfid*' xattrs to store its configurations and accounting information and also to build the parent inode chain in case of absense of path. Problem: After disabling and then enabling quota back, the xattrs may contain stale data leading to impaired accounting and thus improper enforcement. Solution: Clean up all the quota related xattrs after quota disable. Marker xlator implements a virtual xattr to cleanup quota and pgfid xattrs. In this approach glusterd mounts an auxiliary mount and sends the below command to all the files by crawling the mountpoint. #setfattr -n "glusterfs.quota-xattr-cleanup" -v 1 <path/to/file> Credit: Krishnan Parthasarathi <kparthas@redhat.com> Varun Shastry <vshastry@redhat.com> Change-Id: I9380eca58a285dc27dd572de1767aac8f2cd8049 BUG: 969461 Signed-off-by: Varun Shastry <vshastry@redhat.com> Reviewed-on: http://review.gluster.org/6369 Reviewed-by: Raghavendra G <rgowdapp@redhat.com> Tested-by: Gluster Build System <jenkins@build.gluster.com> Reviewed-by: Krishnan Parthasarathi <kparthas@redhat.com> Reviewed-by: Vijay Bellur <vbellur@redhat.com>

This leads to incorrect identification of holes or overlaps. We need to ignore layouts, which have err == 0, and start == stop. In the current scenario (start == stop == 0). Additionally, in layout-merge, treat missing xattrs as err = 0. In case of missing layouts, anomalies will reset them. For any other valid subvoles, err != 0 in case of layouts being zeroed out. Also reverted back dht_selfheal_dir_xattr, which does layout calculation only on subvols which have errors.
