This deadlock happens while processing dentry corresponding to current directory (.) in rda_fill_readdirp. In this case following order is followed: LOCK(directory_fd_ctx->lock); rda_inode_ctx_get_iatt -> LOCK(directory_inode->lock); However, in rda_mark_inode_dirty following lock order is followed: LOCK(directory_inode->lock); LOCK(directory_fd_ctx->lock); these two codepaths when executed concurrently resulted in a deadlock. Current patch fixes this by removing locking directory inode and fd-ctx in rda_fill_readdirp. This is fine as directory inode's stat won't change due to writes to files within directory.

Gluster
Gluster is a software defined distributed storage that can scale to several petabytes. It provides interfaces for object, block and file storage.
Development
Contributions to gluster in the form of patches and new feature additions can be made by following steps outlined at Developers Guide.
Documentation
The Gluster documentation can be found at Gluster Docs.
Deployment
Quick instructions to build and install can be found in INSTALL file.
Testing
GlusterFS source contains some functional tests under tests/
directory. All
these tests are run against every patch submitted for review. If you want your
patch to be tested, please add a .t
test file as part of your patch submission.
You can also submit a patch to only add a .t
file for the test case you are
aware of.
To run these tests, on your test-machine, just run ./run-tests.sh
. Don't run
this on a machine where you have 'production' glusterfs is running, as it would
blindly kill all gluster processes in each runs.
If you are sending a patch, and want to validate one or few specific tests, then run a single test by running the below command.
bash# /bin/bash ${path_to_gluster}/tests/basic/rpc-coverage.t
You can also use prove
tool if available in your machine, as follows.
bash# prove -vmfe '/bin/bash' ${path_to_gluster}/tests/basic/rpc-coverage.t
