glusterfsd: Continuous errors are getting in mount logs while glusterd is down

2016-11-10T14:45:19+00:00

Problem: when glusterd is down, getting the continuous mgmt_rpc_notify errors
         messages in the volume mount log for every 3 seconds,it will
         consume disk space.

Solution: To reduce the frequency of error messages use GF_LOG_OCCASIONALLY.

http://review.gluster.org/14085 fixes a/the "leak" - via the
generated rpc/xdr headers - of pragmas that mask these warnings.

However 14085 won't pass the smoke test until all the warnings are

feature/bitrot: Ondemand scrub option for bitrot

2016-08-25T21:39:38+00:00

The bitrot scrubber takes 'hourly/daily/biweekly/monthly'
as the values for 'scrub-frequency'. There is no way
to schedule the scrubbing when the admin wants it.

Ondemand scrubbing brings in the new option 'ondemand'
with which the admin can start scrubbing ondemand.
It starts the scrubbing immediately.

Ondemand scrubbing is successful only if the scrubber
is in 'Active (Idle)' (waiting for it's next frequency
cycle to start scrubbing). It is not entertained when
the scrubber is in 'Paused' or already running.

Here is the command line syntax.

gluster volume bitrot  scrub ondemand

mgmt: remove unused and misleading pmap_signup

2016-07-08T04:26:26+00:00

We use signin, but not signup.  Having both just introduces confusion.
The proc number has been retained to avoid changes to the numbering of
other procs, and the mapping to a name has similarly been retained as a
placeholder, but the code and structure definitions have been removed.

glusterd-client: switch volfile server incase existing connection breaks

2016-04-12T12:14:22+00:00

Problem:
Currently, say we have 10 Node gluster volume, and mounted it using
Node 1 (N1) as volfile server and the rest as backup volfile servers

$ mount -t glusterfs -obackup-volfile-servers=::...: :/vol /mnt

if N1 goes down we still be able to access the same mount point,
but the problem is that if we add or remove bricks to the volume
whoes volfile server is down in our case N1, that info will not be
passed to client, because connection between glusterfs and glusterd (of N1)
will be disconnected due to which we cannot store files to the newly
added bricks until N1 comes back

Solution:
If N1 goes down iterate through the nodes specified in
backup-volfile-servers list and try to establish the connection between
glusterfs and glsuterd, hence we don't really have to wait
until N1 comes back to store files in newly added bricks that are
successfully added when N1 was down

glusterd: Bug fixes for IPv6 support

2016-02-20T17:16:42+00:00

Problem:
Glusterd not working using ipv6 transport. The idea is with proper glusterd.vol configuration,
1. glusterd needs to listen on default port (240007) as IPv6 TCP listner.
2. Volume creation/deletion/mounting/add-bricks/delete-bricks/peer-probe
   needs to work using ipv6 addresses.
3. Bricks needs to listen on ipv6 addresses.
All the above functionality is needed to say that glusterd supports ipv6 transport and this is broken.

Fix:
When "option transport.address-family inet6" option is present in glusterd.vol
file, it is made sure that glusterd creates listeners using ipv6 sockets only and also the same information is saved
inside brick volume files used by glusterfsd brick process when they are starting.

Tests Run:
Regression tests using ./run-tests.sh
    IPv4: Ran manually till tests/basic/rpm.t .
    IPv6: (Need to add the above mentioned config and also add an entry for "hostname ::1" in /etc/hosts)
        Started failing at ./tests/basic/glusterd/arbiter-volume-probe.t and ran successfully till here

    peer probe
    add-bricks
    remove-bricks
    create volume
    replace-bricks
    start volume
    stop volume
    delete volume

glusterfsd: destroy frame after rebalance callback has completed

2016-02-16T02:40:22+00:00

Rebalance after sending a status notification immediately
destroys the frame. Now in its callback the frame is corrupted.
Rebalance crashes when this corrupted frame is accessed. To avoid
this we must destroy the frame after the callback is completed.
