* read-ahead: re-enable support for variable page sizeAnand Avati2013-02-201-1/+12
| | | | | | | | | | | | | | | | Support for variable size page-size was disabled with the introduction of fixed size iobufs. Since the introduction of variable sized iobufs there is no reason to not have configurable page-size in read-ahead. This patch enables necessary changes in the translator for configurable page-size.

* cluster/afr: do complete split-brain check in all the fd based fopsRaghavendra Bhat2013-02-194-19/+33
| | | | | | | | | | | | | | | | | fd based operations such as readv checked only for data split brain instead of complete split-brain (i.e both data + metadata) assuming that open would have done the complete split-brain check. However open-behind would have unwound open, without winding to afr thus preventing the complete split-brain check and some appliations will be able to read the contents of the file even though the file has metadata split-brain. So let all the fd based fops do a defensive check of complete split-brain.

* distribute: add hash-name-regex optionJeff Darcy2013-02-186-24/+135
| | | | | | | | | | | | | | | | | | | | | This is to support the common "write to temp file then rename" idiom. In our case this causes us to create a linkfile during the rename in (N-1)/N cases, with a significant impact on performance e.g. for UFO which uses this idiom. This patch allows the user to specify up to two regular expressions that separate the permanent and transient parts of a temp-file name: rsync-hash-regex reimplements the existing RSYNC_FRIENDLY_NAME pattern where the temporary name for EXAMPLE is .EXAMPLE.suffix extra-hash-regex can be used for a second pattern, active concurrently, and can include alternatives via the POSIX extended-regex syntax Change-Id: Ic1a6ed19324bc31fefe91ee34b8478877a9c5d2c BUG: 912564 Signed-off-by: Jeff Darcy <jdarcy@redhat.com> Reviewed-on: http://review.gluster.org/4116 Tested-by: Gluster Build System <jenkins@build.gluster.com> Reviewed-by: Anand Avati <avati@redhat.com>

The second rejects them with EPERM. The third turns off protection for that directory.

| | | | | | | | | | | | | | | | | | | | Since directories have presence on all subvolumes there is no definite meaning of ->hashed_subvol or ->cached_subvol. getxattr() code path chooses ->cached_subvol for pathinfo extended attribute. While this makes sense of files, it makes less sense for directories. Further if a hashed or a cached subvolume is down, and there's a getxattr request for a directory, we return with an errno. This patch changes pathinfo extended attribute contents by aggregating information from all subvolumes that are up.

* glusterfsd can't listen in a specified addressmerfi2013-02-071-1/+1
| | | | | | | | | | | | | | | | | | | | When specifying transport.socket.bind-address option, only the glusterd daemon uses this address. But glusterfsd still working with the default localhost address. For instance, when we want to use an IPV6 specific address we will want that all process use that specified address even glusterfsd. To handle this change we just need to replace the fixed address “localhost” to the specified brick address “brickinfo->hostname” Change-Id: I540d30e6c155f71379a1cf1c0b459ac00faeb62c BUG: 865327 Signed-off-by: Lahoucine BENLAHMR <lahoucine@benlahmr.com> Reviewed-on: http://review.gluster.org/3889 Tested-by: Gluster Build System <jenkins@build.gluster.com> Reviewed-by: Anand Avati <avati@redhat.com>

* dht: better layout-optimization algorithmJeff Darcy2013-02-072-22/+76
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This method deals with the case where swapping might gain a bigger overlap for the xlator currently under consideration, but sacrifices even more from the xlator we're swapping with. For example: A = 0x00000000 - 0x44444443 (new 0x00000000 - 0x55555554) B = 0x44444444 - 0x77777776 (new 0x55555555 - 0xaaaaaaa9) C = 0x77777777 - 0xffffffff (new 0xaaaaaaaa - 0xffffffff) Here, the new range for B has a bigger overlap with the old C than with the old B (0x33333333 vs. 0x22222222 to be precise) so looking only at that might lead us to swap. However, such a swap turns the new C's overlap from 0x55555556 (vs. old C) to *zero* (vs. old B). In other words, we've gained 0x11111111 for B but lost 0x55555556 for C, so it's a bad idea. The new algorithm accounts for all effects of the swap, so it not only avoids bad swaps but can make some good ones that would have been missed previously. For example, if swapping a range X with a later range Y would not increase the overlap for X we would previously have skipped it even if the swap would increase Y's overlap without affecting X's. This is the normal case when we're adding a new brick (which initially has zero overlap with any old range) so finding more good swaps is probably even more important than avoiding bad ones. Also, the logic in dht_overlap_calc was completely broken before, causing integer overflows instead of providing correct values, so no matter what higher-level algorithm was in place the GIGO effect would have resulted in bad decisions.
