During a peer-handshake, after the volumes have synced, and the list of
missed snapshots have synced, the node will perform the pending deletes
and restores on this list. At this point, the current snapshot list in
the node will be updated, and hence in case of conflicts arising during
snapshot handshake, the peer hosting the bricks will be given precedence
Likewise, if there will be a conflict, and both peers will be in the same
state, i.e either both would be hosting bricks or both would not be hosting
bricks, then a decision can't be taken and a peer-reject will happen.
glusterd_compare_and_update_snap() implements the following algorithm to
perform the above task:
Step 1: Start.
Step 2: Check if the peer is missing a delete on the said snap.
If yes, goto step 6.
Step 3: Check if there is a conflict between the peer's data and the
local snap. If no, goto step 5.
Step 4: As there is a conflict, check if both the peer and the local nodes
are hosting bricks. Based on the results perform the following:
Peer Hosts Bricks Local Node Hosts Bricks Action
Yes Yes Goto Step 7
No No Goto Step 7
Yes No Goto Step 8
No Yes Goto Step 6
Step 5: Check if the local node is missing the peer's data.
If yes, goto step 9.
Step 6: It's a no-op. Goto step 10
Step 7: Peer Reject. Goto step 10
Step 8: Delete local node's data.
Step 9: Accept Peer Data.
Step 10: Stop

During a glusterd handshake, a dictionary is passed among
the peers which contains, info of volumes, global opts,
and now also info of snaps and list of missed snaps
As it now contains more than just volume specific data,
renaming the dict in the code-base from "vols" to "peer_data"

node reboot.
The lvm snapshots of the bricks are mounted at /var/run/gluster/snaps/ or
/run/gluster/snaps. These paths being on a tempfs, on reboot are removed.
So when glusterd starts, we need to recreate these paths, activate the
respective logical volumes (lvm snapshots of the bricks), and mount
these logical volumes at their respective paths.

This data will be stored on disk at /var/lib/glusterd/snaps/missed_snaps_list
In memory we maintain the data as a list of glusterd_missed_snap_info
in conf, the key for this list are the first two fields,
i.e NODE-UUID:SNAP-UUID.
For every NODE-UUID:SNAP-UUID, there can be multiple operations missed
on multiple bricks. So we maintain a list of glusterd_snap_op_t
for every node of glusterd_missed_snap_info
This list is maintained or updated during snapshot create, delete, and restore
operations which are the only operations that if missed, are recorded in this
list.
During snapshot create, if a node is down, or a brick is down, we don't
receive their mount point infos. snap_status of such bricks is marked as
-1, and their brick details are added to this list.
During snapshot delete, we check from originator node, if any other
nodes, holding bricks of the said snap are down. Those are also added to the list.
Also if the node is up, but the snapshot was pending for a snap
brick, and its snap_status is -1, we add that to the list too.
When a subsequent delete entry is processed for an already existing
create entry, we just mark the create entries status as done (2), and don't
add the delete entry to the list.
During snapshot restore, we check from originator node, if any other
nodes, holding bricks of the said snap are down. Those are also added to the list.
Also if the node is up, but the snapshot was pending for a snap
brick, and its snap_status is -1, we add that to the list too.
Like delete when a subsequent restore entry is processed for an already existing
create entry, we just mark the create entries status as done (2), and don't
add the restore entry to the list.

This patch improves the validation for the 'peer detach' command.
A check for if volumes exist with some bricks on the peer being detached
validation is added in peer detach code flow (even force would have this
validation).
This patch also gurantees that peer detach doesn't fail for a volume with all
its brick on the peer which is getting detached and there are no other bricks on
this peer.
The following steps need to be followed for removing a downed and unrecoverable
peer.
* If a replacement system is available
- add it to the cluster
- use replace-brick to migrate bricks of the downed peer to the new
peer (since data cannot be recovered anyway use the 'replace-brick
commit force' command)
or,
If no replacement system is available,
- remove bricks of the downed peer using 'remove-brick'

cluster op-version must be atleast 4 for add/remove brick to proceed.
This change is required for the new afr-changelog xattr changes that
will be done for glusterFS 3.6 (http://review.gluster.org/#/c/7155/).
In add-brick, the check is done only when replica count is increased
because only that will affect the AFR xattrs.
In remove-brick, the check is unconditional failing which there will be
inconsistencies in the client xlator names amongst the volfiles of
different peers.

With this patch we are replacing the existing cluster-wide
lock taken on glusterds across the cluster, with volume locks
which are also taken on glusterds across the cluster, but are
volume specific. So with the volume locks we are able to perform
more than one gluster operation at the same time, as long as the
operations are being performed on different volumes.
We maintain a global list of volume-locks (using a dict for a list)
where the key is the volume name, and which saves the uuid of the
originator glusterd. These locks are held and released per volume
transaction.
In order to acheive multiple gluster operations occuring at the
same time, we also separate opinfos in the op-state-machine, as a
part of this patch. To do so, we generate a unique transaction-id
(uuid) per gluster transaction. An opinfo is then associated with
this transaction id, which is used throughout the transaction. We
maintain a run-time global list(using a dict) of transaction-ids,
and their respective opinfos to achieve this.

This patch only removes lines of code. For personal gratification, giving a
detailed explanation of what the problem was.
When glusterd spawns the local brick process, say when a reboot of the node
occurs,the glusterd_brick_start() and subsequently the
glusterd_volume_start_glusterfs() function gets called twice; from
glusterd_spawn_daemons() and glusterd_do_volume_quorum_action() respectively.
This causes a race, best described by a pseudo-code of current behaviour.
glusterd_volume_start_glusterfs()
{
if(!brick process running) {
step-a) reap pid file( i.e. unlink it)
step-b) fork a brick process which creates and locks pid file and
binds the process to a socket.
}
}
Time Event
---- -----
T1 Call-1 arrives, completes step-a, starts step-b
T2 Call-2 arrives, enters step-a as Call-1's forked child is not
yet running.
T3 Call-1's forked child is alive, creates pidfile and locks it,binds
its address to a socket.
T4 Call-2 performs step-a; i.e.unlinks the pid file created by Call-1 !!
(files can still be stil be unlinked despite a lockf on it)
T5 Call-2 does step-b, and the forked child process creates a *new* pid file
with it's pid and locks this file.
T6 But Call-2's brick process is not able to bind to socket as it
is already in use (courtesy T3) and hence exits (so no locks anymore on the pidfile).
Result:
- Pid file now contains PID of an extinct brick process.
- `gluster volume status` shows this PID value. It also notices that there is no
lock held on pid file by the currently running brick process (created by Call-1)
and hence shows N/A for the online status.
Also, as a result of events at T4, "ls -l /proc/<brick process PID>/fd/pidfile"
shows up as deleted.
Fix:
1.Do not unlink pid file. i.e. avoid step-a. Now at T5,Call-2's brick process
cannot obtain lock on pid file (Call-1's process still holds it) and exits.
2. Unrelated, but remove lock-unlock sequence in glusterfs_pidfile_setup()
which does not seem to be doing anything useful.

The defrag sockfile was moved from priv->workdir to
DEFAULT_VAR_RUN_DIRECTORY. The format for the new path of the defrag
sockfile is 'DEFAULT_VAR_RUN_DIRECTORY/gluster-rebalance-<vol-id>.sock'.
This was needed because the earlier location didn't have a fixed length
and could exceed UNIX_PATH_MAX characters. This could lead to the
rebalance process failing to start as the socket file could not be
created.
Also, for keeping backward compatiblity, glusterd_rebalance_rpc_create
will try both the new and old sockfile locations when attempting
reconnection.

Trying to stop rebalance process via RPC using the GD_SYNCOP macro,
could lead to glusterd crashing. In case of an implicit volume update,
which happens when a peer comes back up, the stop function would be
called in the epoll thread. This would lead to glusterd crashing as the
epoll thread doesn't have synctasks for the GD_SYNCOP macro to make use
of.
Instead of using the RPC method, we now terminate the rebalance process
by kill(). The rebalance process has been designed to be resistant to
interruption, so this will not lead to any data corruption.
Also, when checking for stale rebalance task, make sure that the old
task-id is not null.

rpc:
- On a RPC_TRANSPORT_CLEANUP event, rpc_clnt_notify calls the registered
notifyfn with a RPC_CLNT_DESTROY event. The notifyfn should properly
cleanup the saved mydata on this event.
- Break the reconnect chain when an rpc client is disabled. This will
prevent new disconnect events which can lead to crashes.
glusterd:
- Added support for RPC_CLNT_DESTROY in glusterd_brick_rpc_notify
- Use a common glusterd_rpc_clnt_unref() function throught glusterd in
place of rpc_clnt_unref(). This function correctly gives up the
big-lock before performing the unref.

A dictionary was added to store additional information of a rebalance
process, like the bricks being removed in case of a rebalance started
by remove-brick. This dictionary wasn't being stored/restored or synced
during volume sync, leading to errors like a volume status command
failing. These issues have been fixed in this patch. The rebalance dict
is now stored/restored and also exported/imported during volume sync.
Also, this makes sure that the rebalance dict is only create on
remove-brick start. This adds a bricks decommissioned status to the
information imported/exported during volume sync.

Glusterd will now correctly copy existing rebalance information when a
volinfo is updated during volume sync. If the existing rebalance
information was stale, then any existing rebalance process will be
termimnated. A new rebalance process will be started only if there is no
existing rebalance process. The rebalance process will not be started if
the existing rebalance session had completed, failed or been stopped.

Previously, glusterd used to just send back the local status of a task
in a 'volume status [tasks]' command. As the rebalance operation is
distributed and asynchronus, this meant that different peers could give
different status values for a rebalance or remove-brick task.
With this patch, all the peers will send back the tasks status as a part
of the 'volume status' commit op, and the origin peer will aggregate
these to arrive at a final status for the task.
The aggregation is only done for rebalance or remove-brick tasks. The
replace-brick task will have the same status on all the peers (see
comment in glusterd_volume_status_aggregate_tasks_status() for more
information) and need not be aggregated.
The rebalance process has 5 states,
NOT_STARTED - rebalance process has not been started on this node
STARTED - rebalance process has been started and is still running
STOPPED - rebalance process was stopped by a 'rebalance/remove-brick
stop' command
COMPLETED - rebalance process completed successfully
FAILED - rebalance process failed to complete successfully
The aggregation is done using the following precedence,
STARTED > FAILED > STOPPED > COMPLETED > NOT_STARTED
The new changes make the 'volume status tasks' command a distributed
command as we need to get the task status from all peers.
The following tests were performed,
- Start a remove-brick task and do a status command on a peer which
doesn't have the brick being removed. The remove-brick status was
given correctly as 'in progress' and 'completed', instead of 'not
started'
- Start a rebalance task, run the status command. The status moved to
'completed' only after rebalance completed on all nodes.
Also, change the CLI xml output code for rebalance status to use the
same algorithm for status aggregation.

Gluster was starting rebalance processes on peers where it wasn't
required in two cases.
- For a normal rebalance command on a volume, rebalance processes were
started on all peers instead of just the peers which contain bricks of
the volume
- For rebalance process being restarted by a volume sync, caused by a
new peer being probed or a peer restarting, rebalance processes were
started on all peers, for both a normal rebalance and for remove-brick
needing rebalance.
This patch adds a new check before starting rebalance process in the
above two cases.
- For rebalance process required by a rebalance command, each peer will
check if it contains atleast one brick of the volume
- For rebalance process required by a remove-brick command, each peer
will check if it contains atleast one of the bricks being removed

Implement reconfigure() for NFS xlator so that volume set/reset wont
restart the NFS server process. But few options can not be reconfigured
dynamically e.g. nfs.mem-factor, nfs.port etc which needs NFS to be
restarted.

Current BD xlator (block backend) has a few limitations such as
* Creation of directories not supported
* Supports only single brick
* Does not use extended attributes (and client gfid) like posix xlator
* Creation of special files (symbolic links, device nodes etc) not
supported
Basic limitation of not allowing directory creation is blocking
oVirt/VDSM to consume BD xlator as part of Gluster domain since VDSM
creates multi-level directories when GlusterFS is used as storage
backend for storing VM images.
To overcome these limitations a new BD xlator with following
improvements is suggested.
* New hybrid BD xlator that handles both regular files and block device
files
* The volume will have both POSIX and BD bricks. Regular files are
created on POSIX bricks, block devices are created on the BD brick (VG)
* BD xlator leverages exiting POSIX xlator for most POSIX calls and
hence sits above the POSIX xlator
* Block device file is differentiated from regular file by an extended
attribute
* The xattr 'user.glusterfs.bd' (BD_XATTR) plays a role in mapping a
posix file to Logical Volume (LV).
* When a client sends a request to set BD_XATTR on a posix file, a new
LV is created and mapped to posix file. So every block device will
have a representative file in POSIX brick with 'user.glusterfs.bd'
(BD_XATTR) set.
* Here after all operations on this file results in LV related
operations.
For example opening a file that has BD_XATTR set results in opening
the LV block device, reading results in reading the corresponding LV
block device.
When BD xlator gets request to set BD_XATTR via setxattr call, it
creates a LV and information about this LV is placed in the xattr of the
posix file. xattr "user.glusterfs.bd" used to identify that posix file
is mapped to BD.
Usage:
Server side:
[root@host1 ~]# gluster volume create bdvol host1:/storage/vg1_info?vg1 host2:/storage/vg2_info?vg2
It creates a distributed gluster volume 'bdvol' with Volume Group vg1
using posix brick /storage/vg1_info in host1 and Volume Group vg2 using
/storage/vg2_info in host2.
[root@host1 ~]# gluster volume start bdvol
Client side:
[root@node ~]# mount -t glusterfs host1:/bdvol /media
[root@node ~]# touch /media/posix
It creates regular posix file 'posix' in either host1:/vg1 or host2:/vg2 brick
[root@node ~]# mkdir /media/image
[root@node ~]# touch /media/image/lv1
It also creates regular posix file 'lv1' in either host1:/vg1 or
host2:/vg2 brick
[root@node ~]# setfattr -n "user.glusterfs.bd" -v "lv" /media/image/lv1
[root@node ~]#
Above setxattr results in creating a new LV in corresponding brick's VG
and it sets 'user.glusterfs.bd' with value 'lv:<default-extent-size'
[root@node ~]# truncate -s5G /media/image/lv1
It results in resizig LV 'lv1'to 5G
New BD xlator code is placed in xlators/storage/bd directory.
Also add volume-uuid to the VG so that same VG can't be used for other
bricks/volumes. After deleting a gluster volume, one has to manually
remove the associated tag using vgchange <vg-name> --deltag
<trusted.glusterfs.volume-id:<volume-id>>
Changes from previous version V5:
* Removed support for delayed deleting of LVs
Changes from previous version V4:
* Consolidated the patches
* Removed usage of BD_XATTR_SIZE and consolidated it in BD_XATTR.
Changes from previous version V3:
* Added support in FUSE to support full/linked clone
* Added support to merge snapshots and provide information about origin
* bd_map xlator removed
* iatt structure used in inode_ctx. iatt is cached and updated during
fsync/flush
* aio support
* Type and capabilities of volume are exported through getxattr
Changes from version 2:
* Used inode_context for caching BD size and to check if loc/fd is BD or
not.
* Added GlusterFS server offloaded copy and snapshot through setfattr
FOP. As part of this libgfapi is modified.
* BD xlator supports stripe
* During unlinking if a LV file is already opened, its added to delete
list and bd_del_thread tries to delete from this list when a last
reference to that file is closed.
Changes from previous version:
* gfid is used as name of LV
* ? is used to specify VG name for creating BD volume in volume
create, add-brick. gluster volume create volname host:/path?vg
* open-behind issue is fixed
* A replicate brick can be added dynamically and LVs from source brick
are replicated to destination brick
* A distribute brick can be added dynamically and rebalance operation
distributes existing LVs/files to the new brick
* Thin provisioning support added.
* bd_map xlator support retained
* setfattr -n user.glusterfs.bd -v "lv" creates a regular LV and
setfattr -n user.glusterfs.bd -v "thin" creates thin LV
* Capability and backend information added to gluster volume info (and
--xml) so
that management tools can exploit BD xlator.
* tracing support for bd xlator added
TODO:
* Add support to display snapshots for a given LV
* Display posix filename for list-origin instead of gfid
