fuse: add "resolve-gids" mount option to overcome 32-groups limit

2015-09-21T06:45:07+00:00

Add a --resolve-gids commandline option to the glusterfs binary. This
option gets set when executing "mount -t glusterfs -o resolve-gids ...".

This option is most useful in combination with the "acl" mount option.
POSIX ACL permission checking is done on the FUSE-client side to improve
performance (in addition to the checking on the bricks).

The fuse-bridge reads /proc/$PID/status by default, and this file
contains maximum 32 groups. Any local (client-side) permission checking
that requires more than the first 32 groups will fail.

By enabling the "resolve-gids" option, the fuse-bridge will call
getgrouplist() to retrieve all the groups from the user accessing the
mountpoint. This is comparable to how "nfs.server-aux-gids" works.

Note that when a user belongs to more than ~93 groups, the volume option
server.manage-gids needs to be enabled too. Without this option, the
RPC-layer will need to reduce the number of groups to make them fit in
the RPC-header.

nfs: Fixes "Remote I/O error" mount failures

2015-09-06T16:20:25+00:00

- Fixes issue where NFS mount fail with "Remove I/O error" after the
  target directory has been deleted and re-created after the gNFSd has
  already cached the inode of the first generation of the target
  directory.
- The solution is to follow the guidance of the AFR2 comments and
  refresh the inode by deleting it from cache and looking it up
  again.

nfs: make it possible to disable nfs.mount-rmtab

2015-08-18T13:19:48+00:00

When there are many NFS-clients doing very often mount/unmount actions,
the updating of the 'rmtab' can become a bottleneck and cause delays. In
these situations, the output of 'showmount' may be less important than
the responsiveness of the (un)mounting.

By setting 'nfs.mount-rmtab' to the value "/-", the cache file is not
updated anymore, and the entries are only kept in memory.

afr: allow readdir to proceed for directories in split-brain

2015-06-15T16:28:59+00:00

Problem:
afr_read_txn() bails out if read_subvol==-1. This meant that for
directories that were in entry split-brain, FOPS like readdir, access,
stat etc were not allowed.

Fix:
Except for getxattr, all other FOPS are wound on the first up child
of afr.

afr: honour selfheal enable/disable volume set options

2015-06-15T13:18:44+00:00

Backport of  http://review.gluster.org/11012
Note: http://review.gluster.org/9459 is not backported to 3.6 but the change it
makes to afr_get_heal_info() (i.e. handling ret values) is needed for heal info
to work correctly and tests/basic/afr/client-side-heal.t to pass.

--------------------------
afr-v1 had the following volume set options that are used to enable/ disable
self-heals from happening in AFR xlator when loaded in the client graph:
cluster.metadata-self-heal
cluster.data-self-heal
cluster.entry-self-heal

In afr-v2, these 3 heals can happen from the client if there is an inode
refresh. This patch allows such heals to proceed only if the corresponding
volume set options are set to true.

facilitate testing of features we do support.

cluster/dht: Unwind with proper op_ret

2015-05-04T20:25:36+00:00

1. Expected behavior of get_real_filename feature.

A getxattr on a existing dir with glusterfs.get_real_filename:
as key should result in one of the following things.

a. A value returned for that key having the real filename (a file whose
match is a case insensitive match to the filename passed in key).
b. op_ret = -1 and errno set to ENOENT meaning that no such file exists
under the specified dir in any case.
c. op_ret = -1 and errno set to ENODATA. This is a case assuming no
xlator interprets the glusterfs.get_real_filename key and it get
passed down to the posix xlator. Naturally, posix xlator would not
find any xattr with this key and would return ENODATA. This will be
interpreted specially by the caller as the feature not being supported
by underlying glusterfs.

2. What assumptions are wrong?
Initially the key used to be user.glusterfs.get_real_filename.
In that case, when posix xlator did a getxattr call it would have
received ENODATA as error. However, the key has now changed to
glusterfs.get_real_filename. This leads to a EOPNOTSUPP error instead.

Considering the above information, this is a rewrite of
get_real_filename logic in dht.
