rpc: add options to manage socket keepalive lifespan

2017-06-20T04:58:25+00:00

Problem:
Default values for handling socket timeouts for brick responses are
insufficient for aggressive applications such as databases.

Solution:
Add 1:1 gluster options for keepalive, keepalive-idle,
keepalive-interval and keepalive-timeout as per the socket level options
available as per tcp(7) man page.

Default values for options are NOT agressive and continue to be values
which result in default timeout when only the keep alive option is
turned on.

These options are Linux specific and will not be applicable to the
*BSDs.

glusterd: Get maximum supported op-version in a cluster

2017-01-09T05:16:12+00:00

gluster volume get  cluster.opversion gives us the current
op-version on which the cluster is operating. There is no command
that lets the user know the maximum supported op-version that the
cluster can run on.

This patch adds a new global option cluster.max-op-version, that
can be used to retrieve the maximum supported op-version in a
cluster.

Usage:
	# gluster volume get all cluster.max-op-version

Example output:

Option                                  Value
------                                  -----
cluster.max-op-version                  30900

NOTE: The only way to test this feature for now is to set the
GD_OP_VERSION_MAX macro to different values (30800 for 3.8,30900
for 3.9, and so on) and rebuild glusterd. Since the regression test
framework currently doesn't have support to simulate these tests,
there are no accompanying regression tests for this feature. It
should be possible to add tests once glusto comes in and makes it
easier to run a heterogeneous cluster.

io-stats: Add stats for upcall notifications

2016-09-01T03:18:42+00:00

With this patch, there will be additional entries seen in
the profile info:

UPCALL : Total number of upcall events that were sent from
         the brick(in brick profile), and number of upcall
         notifications recieved by client(in client profile)

Cache invalidation events:
-------------------------
CI_IATT : Number of upcalls that were cache invalidation and
         had one of the IATT_UPDATE_FLAGS set. This indicates
         that one of the iatt value was changed.

CI_XATTR : Number of upcalls that were cache invalidation, and
         had one of the UP_XATTR or UP_XATTR_RM set. This indicates
         that an xattr was updated or deleted.

CI_RENAME : Number of upcalls that were cache invalidation,
         resulted by the renaming of a file or directory

CI_UNLINK : Number of upcalls that were cache invalidation,
         resulted by the unlink of a file.

CI_FORGET : Number of upcalls that were cache invalidation,
         resulted by the forget of inode on the server side.

Lease events:
------------
LEASE_RECALL : Number of lease recalls sent by the brick (in
         brick profile), and number of lease recalls recieved
         by client(in client profile)

Note that the sum of CI_IATT, CI_XATTR, CI_RENAME, CI_UNLINK,
CI_FORGET, LEASE_RECALL may not be equal to UPCALL. This is
because, each cache invalidation can carry multiple flags.
Eg:
- Every CI_XATTR will have CI_IATT
- Every CI_UNLINK will also increment CI_IATT as link count is an
iatt attribute.

Also UP_PARENT_DENTRY_FLAGS is currently not accounted for,
as CI_RENAME and CI_UNLINK will always have the flag
UP_PARENT_DENTRY_FLAGS

Commit 6e635284a4411b816d4d860a28262c9e6dc4bd6a introduced a comma
separated list of values to be used as AFR's pending changelogs. If
this xlator option is missing in the volfile, fall back to using client
xlator names for constructing the pending changelog names.

Also, since the aforementioned commit was reverted from 3.7 and 3.8
branches, introduce GD_OP_VERSION_3_9_0 and change the op-version for this
feature to GD_OP_VERSION_3_9_0.
