* storage/posix: honor O_SYNC and O_DSYNC sent in @flags of writev()Anand Avati2013-03-292-5/+10
| | | | | | | | | | | | | | | | Historic bug - posix_writev() has been inspecting pfd->flushwrites for performing fsync() after write, instead of @flags for O_SYNC|O_DSYNC. pfd->flushwrites was never set anywhere and is unused completely. This is behavior from the time before anonymous FD where open() had @wbflags param. This is a leftover from that cleanup.

* cluster/afr: fsync() guarantees POST-OP completionAnand Avati2013-03-273-10/+56
| | | | | | | | | | | | | | | | | | | | | | | | AFR now provides a stronger guarantee that fsync() returns only after completely finishing all the deferred/delayed POST-OP on that open file. To acheive this we make a stub out of the returning fsync and register it with the "delayed" frame in afr_changelog_wake_resume(). The delayed frame, after getting woken up and finishing the POST-OP will call_resume() the registered stub (which UNWINDs the fsync) at the time of frame destruction. This provides a guarantee that an application's (or FUSE) fsync() returns only after finishing up all the previous transactions, including delayed POST-OPs and UNLOCK.

* cluster/afr: ensure DATA operations are made durable before POST-OPAnand Avati2013-03-274-22/+314
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The changelogging scheme of AFR stores information about the state of all replicas in all replicas (in the extended attribute of the respective files on each server) in the form of 'pending counts' of operations (effectively "dirty flags"). These xattrs are blindly trusted while performing self-heal, and therefore utmost care has to be taken while updating and maintaing them. The most critical updation is the clearing of the pending counts corresponding to the *other* server in the changelog of a given server. Before clearing the pending count, we need durability guarantee of the write which was performed on the other server. To obtain such a guarantee, it may be necessary to explicitly introduce an fsync() phase (if the file itself wasn't already opened with O_SYNC). This patch introduces the detection of unstable stable writes on a file and issues explicit fsync() on the servers before performing the POST-OP clearing of pending flags.

* config: better (i.e. more portable) test for libxml2Kaleb S. KEITHLEY2013-03-251-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Over the weekend I tried to build on MacOS X¹ and ran into the following issues: 1) The recent change to autogen.sh to test for pkg-config falls down. 2) After removing the pkg-config test in autogen.sh, w/o pkg-config the PKG_CHECK_MODULES macro invocation in configure[.ac] falls down. N.B. Solaris users run into this too, even through there's a (broken) pkg-config package that can be installed. 3) There are other problems in the code related to fuse that are beyond the scope of this. It seems that pkg-config is only a requirement for the definition of the PKG_CHECK_MODULES macro used to detect libxml2. Since this seems to be inherently unportable — at least to MacOS X and Solaris — I'd like to: A) Change the use of the PKG_CHECK_MODULES macro to the more portable AM_PATH_XML2 macro provided by the libxml2 package in /usr/.../share/aclocal/libxml.m4 2) Revisit the decision to add the check for pkg-config in autogen.sh in BZ 921817. For now this is just an rfc. If people are agreeable I'll reenter this change against BZ 921817. ¹Mountain Lion 10.8.3, XCode 4.6.1 Change-Id: I237b1ed8919088345b8fd943423b2a6ad289981b BUG: 921817 Signed-off-by: Kaleb S.

* dht: make DHT xattr names configurableJeff Darcy2013-03-2112-125/+198
| | | | | | | | | | | | | | | | | | | | This is necessary to support "DHT over DHT" configurations, so that the upper and lower instances of DHT don't step all over each other. Why would we even consider such a thing? Because it gives us the ability to do data tiering and rack-aware placement, either by themselves or as complements to other functionality such as erasure codes or deduplication which save space but cost performance. By setting up the top-level DHT to place data into one of several lower-level DHT pools based on policy instead of pure elastic hashing, we get better performance for 90% of accesses and better storage efficiency for 90% of data, all for relatively low effort.

Since this is done after data syncing and erase of xattrs, old source and old sink are now sources, but the mtimes of them differ. Old code just takes the first source from the list and update mtimes, which could be sink before the self-heal started. Fix: Set mtime from 'sources before syncing'.

| | | | | | | | | | | | | | | | | | | | Problem: With the present implementation, eager-lock is issued for any fd fop. eager-lock is being transferred to metadata transactions. But the lk-owner is set to local->fd address only for DATA transactions, but for METADATA transactions it is frame->root. Because of this unlock on the eager-lock fails and rebalance hangs.

| | | | | | | | | | | | | | | | | Brick processes listen on all the interfaces on a given port. When multiple glusterds run on one machine, glusterd assumes that it 'owns' the ports on that machine. This can lead to the different glusterd instances to step on each other's ports. This fix ensures that brick processes listen only on the its host IP when glusterd has bind-address option set.

* cluster/afr: Don't queue transactions during open-fd fixPranith Kumar K2013-02-226-385/+167
| | | | | | | | | | | | | | | | | | | | | Before Anonymous fds are available, afr had to queue up transactions if the file is not opened on one of its subvolumes. This happens until the attempt to open the file either succeeds or fails. These attempts happen until the file is successfully opened on the subvolume. Now client xlator uses anonymous fds to perform the fops if the fd used for the fop is not 'opened'. Fops will be successful even when the file is not opened so there is no need to queue up the transactions anymore in afr. Open is attempted on the subvolume where it is not opened independent of the fop.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is needed to support automated testing of cluster-communication features such as probing and quorum. In order to use this, you need to do the following preparatory steps. * Copy /var/lib/glusterd to another directory for each virtual host * Ensure that each virtual host has a different UUID in its glusterd.info Now you can start each copy of glusterd with the following xlator-options. * management.transport.socket.bind-address=$ip_address * management.working-directory=$unique_working_directory You can use 127.x.y.z addresses for binding without needing to assign them to interfaces explicitly. Note that you must use addresses, not names, because of some stuff in the socket code that's not worth fixing just for this usage, but after that you can use names in /etc/hosts instead. At this point you can issue CLI commands to a specific glusterd using the --remote-host option. So far probe, volume create/start/stop, mount, and basic I/O all seem to work as expected with multiple instances.
