* afr: handle short writes in afr_writev_wind and self-heal to avoid corruptionBrian Foster2012-11-291-0/+94
| | | | | | | | | | | | | | | | | | | | | The current failure to handle short writes on writev fops leaves us open to file corruption. A short write on a user request is ignored and leaves replicas in an inconsistent state. A short write during a self-heal is ignored and incorrectly marks the files as consistent if the heal completes. Modify user writev handling to return the best case return value from each of the replicas. Short writes that occur relative to this value are marked as failed and will require a heal. Modify self-heal to set an error on a short write and abort the heal.

* glusterd, cli: implement gluster system uuid reset commandRaghavendra Bhat2012-11-281-0/+18
| | | | | | | | | | | | | | | | | | | | | | A commonly faced problem among glusterfs users is: after a fresh installation of glusterfs in a virtual machine, the VM image is cloned to make multiple instances of the server. This breaks glusterd because right after glusterfs installation on the first boot glusterd would have created the node UUID and this gets inherited into the clone. The result is wierd behavior at the time of peer probe where glusterd does not (yet) deal with UUID collisions in a user friendly way. To handle it gluster peer reset command is implemented which upon execution changes the uuid of local glusterd.

* perf/io-threads: least-rate-limit least priority throttlingBrian Foster2012-11-211-0/+37
| | | | | | | | | | | | | | | | | | | | | | | | | | | The 'least-rate-limit' io-threads translator option enables throttling of least priority operations. This is initially intended as a debug/diagnostic tool for users who might experience overloaded servers via background activity (i.e., self-heal). least-rate-limit defines the maximum number of least priority operations the io-threads translator will dequeue in one second. If the specified rate limit is met, the worker threads sleep for the minimal amount of time before the next least priority operation becomes available (or until a new request arrives). The requests/second metric is generic and relative to a variety of factors involved with a background operation (server, storage, etc.). The most recent measured rate ("cached least rate") is added to the io-threads state dump content (kill -USR1) to serve as a reference point to throttle background activity under particular conditions.

But if setup is such that brick is used as a mount point and before executing the <gluster volume start volume-name> command, nothing is mounted on the brick then all the file operations will take place at the brick but actual intention of the brick is to be used as mount point only. FIX: Do not start the volume if extended attribute (trusted.glusterfs.volume-id) is set absent.

* storage/posix: Make rchecksum O_DIRECT friendlyPranith Kumar K2012-11-201-0/+44
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem: When posix-aio is enabled to perform aio fd is set with O_DIRECT whenever possible in read, writev fops. Rchecksum does not take this into account. If either offset/size/memory-buf passed to pread in rchecksum fop is not aligned, pread fails with EINVAL. Fix: Before doing pread necessary O_DIRECT manipulation is done when aio is enabled. Memory buffer passed to pread is now page-aligned. Test: 1) Create replica volume with aio enabled. 2) dd if=/dev/urandom of=a bs=1M count=1 3) kill one of the bricks in the replica pair 4) dd if=/dev/urandom of=a bs=1M count=1 5) bring back the brick. Self-heal succeeds after the change. The test above checks both rchecksum, writev fops that were changed in this patch.

This was fixed by enclosing the entire expected-value expression in double quotes with a simple backslash escape for the end-of-line dollar sign. Second issue is that we were throwing away potentially useful debug information. Fixed by using egrep's -q option to suppress output, and eliminating redirections so that we can see any stderr output related to a script error.

| | | | | | | | | | | | | | | | | | | | | | The internal mount API had no access to the generic mountflags used by mount(2). Thus the "ro" mount option that needs to be passed down to mount(2) as as a mountflag was incorrectly mangled into the fuse-specific mount parameter string (cf. http://review.gluster.com/655). This commit fixes the internal API and the "ro" issue. It also adds a check for the "rw" and "ro" mount options in tests/basic/mount.t.

* tests: pre-commit regression testsAnand Avati2012-10-185-0/+231
Framework for writing test cases to be submitted with patches. This framework and the test cases get exercised by Jenkins in the pre-commit regression test. Jenkins is configured to give a +1 verified vote only if the regression test passes without failures (which includes test cases added/changed by the patch being tested) Every patch should include a test case (either extensions/changes to existing test cases or add new ones, as appropriate). The test case should be part of the same commit so that both code and test case get reviewed together. Test cases added are cumulative. Every new patch gets tested against its own test case and every test case previously added. A lot of new commits in the near future will be pure test cases (with no code change) which will get added in "catch up" mode. The tool used for implementing test cases is 'prove', and the framework itself is modeled similar to the POSIX compliance filesystem test suite. Under the top level directory, a new directory named 'tests/' is added. This contains top level classifier directories and framework files/scripts. Functionality tests should be created under a classifier directory below 'tests/'. For e.g: tests/basic/mount.t tests/performance/write-behind.t Bugs which get fixed should include a test case script named by the bug id, so that we are guaranteed any new change will not bring the issue back. For e.g: tests/bugs/bug-123456.t Triggering of regression tests in Jenkins is manual at this point as we do not want the entire test suite to run against every revision of a patch while it is still in the review/resubmit cycle.
