cluster/afr : enable inspection & resolution of files in split-brain

2015-03-19T13:33:12+00:00

Part 2/2 patch to enable users analyze and resolve
split-brain.

This patch enables :
1) Users to inspect the files in data and metadata split-brain.
2) Resolve the split-brain.
Both using a series of setfattr commands.

Consider a volume "test" with 2 bricks.

1) To inspect a file f1:
setfattr -n replica.split-brain-choice -v test-client-0 f1
        After the execution of this command, if no read_subvol
is found, reads will be served from test-client-0 (corresponding
to brick-0).

2) To resolve split-brain :
setfattr -n replica.split-brain-heal-finalize -v test-client-0 f1
        Execution of this command will lead to the resolution
of data and metadata split-brain with subvol mentioned in the
command (test-client-0 here) as the source and the rest as sink.

Tests: ls portability regarding dot-files

2015-03-18T10:46:46+00:00

When run as root, BSD ls(1) lists dot-files, which includes
.glusterfs in split-brain-healing.t's usage. This leads to failure.
gfid-self-heal.t suffers the same problem.

Fix by filtering out dot-files in ls(1) output

NB: split-brain-healing.t also requires http://review.gluster.org/9831
to pass on NetBSD.

cluster/afr: When parent and entry read subvols are different, set entry->inode to NULL

2015-02-02T20:07:08+00:00

That way a lookup would be forced on the entry, and its attributes will
always be selected from its read subvol.

afr: Don't write to sparse regions of sink.

2015-01-30T12:02:43+00:00

Problem:
When data-self-heal-algorithm is set to 'full', shd just reads from
source and writes to sink. If source file happened to be sparse (VM
workloads), we end up actually writing 0s to the corresponding regions
of the sink causing it to lose its sparseness.

Fix:
If the source file is sparse, and the data read from source and sink are
both zeros for that range, skip writing that range to the sink.

cluster/afr: split-brain resolution CLI

2015-01-15T09:28:37+00:00

Extend the AFR heal command to include automated split-brain resolution.

This patch [3/3] is the final patch for afr automated split-brain resolution
implementation.

"gluster volume heal  [full | statistics [heal-count [replica
]] |info [healed | heal-failed | split-brain]| split-brain
{bigger-file  |source-brick  []}]"

The new additions being:
1.gluster volume heal  split-brain bigger-file 
Locates the replica containing the FILE, selects bigger-file as source and
completes heal.

2.gluster volume heal  split-brain source-brick 

Selects  present in  as source and completes heal.

3.gluster volume heal  split-brain 
Selects all split-brained files in  as source and completes
heal.

Note:  can be either the full file name as seen from the root of the
volume (or) the gfid-string representation of the file, which sometimes gets
displayed in the heal info command's output.

Entry/gfid split-brain resolution is not supported.

Example can be found in the test case.
