* glusterd/store: Move remove-brick/rebalance status to node_state.infoshishir gowda2012-05-051-0/+3
| | | | | | | | | | | | | | Hence forth, all node related info, which does not need chksum or versioning can be stored in this file. This data might not be in sync across nodes, as it contains only information related to local node.

* glusterd: Added init scripts like interface for gluster commandsKrishnan Parthasarathi2012-03-311-0/+23
| | | | | | | | | | | | | | | | | | | | | | | | | | Directories to hold the scripts mentioned above would be created for each gluster command under glusterd's 'working dir' as follows: (eg.) <glusterd-working-dir>/hooks/version/create/pre <glusterd-working-dir>/hooks/version/create/post where, version corresponds to the version of hook scripts. The scripts beginning with 'S' under the above directories would be run before (pre) and after (post) the volume created. The scripts would receive a command line argument as below: --volname=<volname> This can be optionally used by the script.

* glusterd: auth allow enhancementsRajesh Amaravathi2012-02-201-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * PROBLEM: When address-based authentication is enabled on a volume, the gNfs server, self-heal daemon (shd), and other operations such as quota, rebalance, replace-brick and geo-replication either stop working or the services are not started if all the peers' ipv{4,6} addresses or hostnames are not added in the "set auth.allow" operation, breaking the functionality of several operations. E.g: volume vol in a cluster of two peers: /mnt/brick1 in 192.168.1.4 /mnt/brick2 in 192.168.1.5 option auth.allow 192.168.1.6 (allow connection requests only from 192.168.1.6) This will disrupt the nfs servers on 192.168.1.{4,5}. brick server processes reject connection requests from both nfs servers (on 4,5), because the peer addresses are not in the auth.allow list. Same holds true for local mounts (on peer machines), self-heal daemon, and other operations which perform a glusterfs mount on one of the peers. * SOLUTION: Login-based authentication (username/password pairs, henceforth referred to as "keys") for gluster services and operations. These *per-volume* keys can be used to by-pass the addr-based authentication, provided none of the peers' addresses are put in the auth.reject list, to enable gluster services like gNfs, self-heal daemon and internal operations on volumes when auth.allow option is exercised. * IMPLEMENTATION: 1. Glusterd generates keys for each volume and stores it in memory as well as in respective volfiles. A new TRUSTED-FUSE volfile is generated which is fuse volfile + keys in protocol/client, and is named trusted-<volname>-fuse.vol. This is used by all local mounts. ANY local mount (on any peer) is granted the trusted-fuse volfile instead of fuse volfile via getspec. non-local mounts are NOT granted the trusted fuse volfile. 2. The keys generated for the volume is written to each server volfile telling servers to allow users with these keys. 3. NFS, self-heal daemon and replace-brick volfiles are updated with the volume's authentication keys. 4. The keys are NOT written to fuse volfiles for obvious reasons. 5. The ownership of volfiles and logfiles is restricted to root users. 6. Merging two identical definitions of peer_info_t in auth/addr and rpc-lib, throwing away the one in auth/addr. 7. Code cleanup in numerous places as appropriate. * IMPORTANT NOTES: 1. One SHOULD NOT put any of the peer addresses in the auth.reject list if one wants any of the glusterd services and features such as gNfs, self-heal, rebalance, geo-rep and quota. 2. If one wants to use username/password based authentication to volumes, one shall append to the server, nfs and shd volfiles, the keys one wants to use for authentication, *while_retaining those_generated_by_glusterd*. See doc/authentication.txt file for details.

| | | | | | | | | | | | | | | | | earlier, sub_count was having different meaning depending on the volume type. now, for replica and stripe count, one can directly access the 'replica_count' or 'stripe_count' to get the corresponding value from the volume info. 'sub_count' is preserved as is for backward compatibility. there is a new variable 'dist_leaf_count' to get info about how many bricks are present in one distribute sub volume.

* support for de-commissioning a node using 'remove-brick'Amar Tumballi2011-09-131-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | to achieve this, we now create volume-file with 'decommissioned-nodes' option in distribute volume, then just perform the rebalance set of operations (with 'force' flag set). now onwards, the 'remove-brick' (with 'start' option) operation tries to migrate data from removed bricks to existing bricks. 'remove-brick' also supports similar options as of replace-brick. * (no options) -> works as 'force', will have the current behavior of remove-brick, ie., no data-migration, volume changes. * start (starts remove-brick with data-migration/draining process, which takes care of migrating data and once complete, will commit the changes to volume file) * pause (stop data migration, but keep the volume file intact with extra options whatever is set) * abort (stop data-migration, and fall back to old configuration) * commit (if volume is stopped, commits the changes to volumefile) * force (stops the data-migration and commits the changes to volume file) Change-Id: I3952bcfbe604a0952e68b6accace7014d5e401d3 BUG: 1952 Reviewed-on: http://review.gluster.com/118 Tested-by: Gluster Build System <jenkins@build.gluster.com> Reviewed-by: Vijay Bellur <vijay@gluster.com>
