storage/posix: Avoid excessive logging in posix.

2012-04-09T17:37:44+00:00

When quota or gsyncd is enabled, the marker translator performs setxattr on
files/directories. If the file/directory is deleted before setxattr, posix gets
an error when it does setxattr and logs it. But its not an error for marker and
it handles the case gracefully. Hence, avoid logging for these keys.

Replace GPLV3 MD5 with OpenSSL MD5

2012-04-04T23:13:21+00:00

Ric asked me to look at replacing the GPL licensed MD5 code with
something better, i.e. perhaps faster, and with a less restrictive
license, etc. So I took a couple hour holiday from working on
wrapping up the client_t and did this.

OpenSSL (nee SSLeay) is released under the OpenSSL license, a BSD/MIT
style license. OpenSSL (libcrypto.so) is used on Linux, OS X and *BSD,
Open Solaris, etc. IOW it's universally available on the platforms we
care about. It's written by Eric Young (eay), now at EMC/RSA, and I
can say from experience that the OpenSSL implementation of MD5 (at least)
is every bit as fast as RSA's proprietary implementation (primarily
because the implementations are very, very similar.) The last time I
surveyed MD5 implementations I found they're all pretty much the same
speed.

I changed the APIs (and ABIs) for the strong and weak checksums.
Strictly speaking I didn't need to do that. They're only called on
short strings of data, i.e. pathnames, so using int32_t and uint32_t
is ostensibly okay. My change is arguably a better, more general API
for this sort of thing. It's also what bit me when gerrit/jenkins
validation failed due to glusterfs segv-ing. (I didn't pay close enough
attention to the implementation of the weak checksum. But it forced me
to learn what gerrit/jenkins are doing and going forward I can do better
testing before submitting to gerrit.)

Now resubmitting with a BZ

core: adding extra data for fops

2012-03-22T23:40:27+00:00

with this change, the xlator APIs will have a dictionary as extra
argument, which is passed between all the layers. This can be
utilized for overloading in some of the operations.

glusterd/rebalance: Bring in support for parallel rebalance

2012-03-08T05:14:27+00:00

This patch, enables rebalance processes to be started on all
nodes where the volume is spread across (1 process per node)

node-uuid xattr identifies which node takes ownership of the
task to migrate the file. The model employed is push (src pushes
to dst)

storage/posix: In lookup check for buf->gfid being NULL

2012-02-29T10:09:59+00:00

There are few cases where create and lookup race.
Lookup ends up getting a valid struct iatt, but with no gfid set.
We need to check for gfid being 0, and handle it as an error.

Introduce new extended attribute: node-uuid

2012-02-23T07:19:44+00:00

Request for trusted.glusterfs.node-uuid returns pathinfo
like string but containing the UUID of glusterd instead
of the backend path for the requested file. This info
is benificial for tasks like parallel rebalance that will
make use of the UUID for data locality.
