glusterd: fail volume delete if one of the node is down

2016-06-13T14:39:46+00:00

Backport of http://review.gluster.org/14681

Deleting a volume on a cluster where one of the node in the cluster is down is
buggy since once that node comes back the resync of the same volume will happen.
Till we bring in the soft delete feature tracked in
http://review.gluster.org/12963 this is a safe guard to block the volume
deletion.

Please note the test file which is backported from this commit has an issue
where we start the volume and then try to delete it which is anyway going to
fail. So the test actually doesn't validate the fix.
http://review.gluster.org/#/c/14693/ in master fixed the problem and the same is
ported as part of this commit as well.

afr: Consider ENOSPC and EDQUOT as symmetric errors

2016-06-13T10:14:49+00:00

Backport of http://review.gluster.org/#/c/14604/

Problem:
Since commit 8eaa3506ead4f11b81b146a9e56575c79f3aad7b, in replica 3, if a
brick is down and a create fails on the other 2 brick with EDQUOT, we consider
it an unsymmetric error and hence do not do post-op. So the dirty xattr
remains set on the parent dir, leading to conservative merges during heal when
all bricks are up. i.e. a file deleted on the source might re-appear after heal.

Fix:
Consider ENOSPC and  EDQUOT as symmetric errors since there is no
possibility of partial inode or entry modification operations possible when
quota is enabled. IOW, if quota reports EDQUOT, the no. of bytes written
(or not written) will be the same on all bricks of the replica.
Likewise, the entry operation (create, mkdir...) will either succeed or
not succeed on all bricks.

nfs: build exportlist with multiple groupnodes

2016-06-13T10:11:00+00:00

The EXPORT procedure of the MOUNT protocol does not correctly create
structures for the 'groupnodes' in the reply. Each 'groupnode' should be
a single entry in the 'nfs.rpc-auth-allow' volume option. Because the
value is handled as a single string, the encoding of the
groupnode->gr_name fails when the value of the volume option is longer
than 255 characters.

In the error case, encoding the EXPORTS reply fails, and the waiting
'showmount' command will not receive a reply and times out.

Splitting the allowed entries and creating a groupnode for each one
prevents the too long ->gr_name. This is following the structures for
the EXPORTS reply in the MOUNT protocol more correctly as well. Note
that the contents of ->gr_name is expected to be server dependent.

This is backport of below mainline fix -

Backport of http://review.gluster.org/#/c/14026/

Introduce cluster.favorite-child-policy which when enabled with
[ctime|mtime|size|majority], automatically heals files that are in
split-brian.

The majority policy will not pick a source if there is no majority.
The other three policies pick the first brick with a valid reply and
non-zero ctime/mtime/size as source.
