| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Whenever new_layout is calculated for a directory, we calculate the number of childs of dht, who will get the actual(Non-zero) layout-range, and assign range to only those subvolume and other will get 0 as their layout->start and layout->stop value. This calculation is based on either a) weight_by_size or b) number of brick who will be assigned the non-zero range So if in case we are not assigning the layout based on weight_by_size, we should choose the "bricks_to_use" instead of "bricks_used". In regression test, we found that priv->du_stat[0].chunks was zero. In this case "bricks_used" variable will be zero, which will cause crash for chunk = ((unsigned long) 0xffffffff) / bricks__used; calculation.

This can happen even with race between rename and directory healing in dht-lookup. This can lead to undefined behaviour while accessing any of both directories. Hence, we are logging paths of both directories, so that a sysadmin can take some corrective action when (s)he sees this log. One of the corrective action can be to copy contents of both directories from backend into a new directory and delete both directories. Since effort involved to fix this issue is non-trivial, giving this workaround till we come up with a fix.

* snapview-server: get the handle if its absent before doing any fopRaghavendra Bhat2014-09-123-34/+177
| | | | | | | | | | | | | | | | | | | | | | | * Now that NFS server does inode linking in readdirp, it can resolve the gfid (i.e. find the right inode from its inode table) present in the filehandle sent by the NFS client on which a fop came. So instead of sending the lookup on that entry, it directly sends the fop. But snapview-server does not get the handle for the entries in readdirp (because doing a lookup on each entry via gfapi would be costly. So it waits till a lookup is done on that inode, to get the handle and the fs instance and fill it in the inode context). So when NFS resoves the gfid and directly sends the fop, snapview-server will not be able to perform the fop as the inode contet would not contain the fs instance and the handle. So fops should check for the handle before doing gfapi calls. If the handle and fs instance are not present in the inode context they should get them by doing an explicit lookup on the entry.

* ec: Removed SSE2 dependencyXavier Hernandez2014-09-118-10272/+11687
| | | | | | | | | | | | | | | | | | | | | | | | | This patch implements the Galois Field multiplications using pure C code without any assembler support. This makes the ec xlator portable to other architectures. In the future it will be possible to use an optimized implementation of the multiplications using architecture dependent facilities (it will be automatically detected and configured). To allow bricks with different machine word sizes to be able to work seamlessly in the same volume, the minimum fragment length to be stored in any brick has been fixed to 512 bytes. Otherwise, different implementations will corrupt the data (SSE2 used 128 bytes, while new implementation would have used 64). This patch also removes the '-msse2' option added on patch http://review.gluster.org/8395/ Change-Id: Iaf6e4ef3dcfda6c68f48f16ca46fc4fb61a215f4 BUG: 1125166 Signed-off-by: Xavier Hernandez <xhernandez@datalab.es> Reviewed-on: http://review.gluster.org/8413 Tested-by: Gluster Build System <jenkins@build.gluster.com> Reviewed-by: Dan Lambright <dlambrig@redhat.com>
