* glusterd/remove-brick: Reset decommission stats on all nodesshishir gowda2012-05-241-0/+2
| | | | | | | | | | | | | | | | Decommissioning is started only on nodes where the bricks which are being decommissioned are present. The stats were reset only when decommission was started. Hence stale stats were being shown on nodes where the bricks were not present.

* common-utils: Simplified mkdir_p interface and put it to use.Krishnan Parthasarathi2012-05-211-9/+0
| | | | | | | | | | | | | | | | | - Simplified mkdir_p interface. - Removed mkdir_if_missing from codebase - Modified glusterd consumers of mkdir_if_missing to use mkdir_p with allow_symlinks=_gf_true. This implicitly assumes that glusterd is in 'control' of the brick path and glusterd's working dir in the sense that the symlinks (if any) in any of the above mentioned paths are under the 'storage administrator's control.

* glusterd: Fixed glusterd_brick_create_path algo.Krishnan Parthasarathi2012-05-161-1/+10
| | | | | | | | | | | | | | | | | | | | | - check if any prefix of the brick path has "trusted.gfid" or "trusted.glusterfs.volume-id" set. - set trusted.glusterfs.volume-id on the bricks as soon as its induction into the volume is settled. Earlier, the setting of "volume-id" used to happen during the first run of the brick process, leaving of window for bricks part of one volume to be (ab)used by another volume inadvertently. - removed creation of brick directory (if missing), during start volume force. This is to avoid directory creation as part 'force'ful starting of volume and leave the responsibility with the user, who understands the 'availability' of the export directory (brick) better.

| | | | | | | | | | | | | | | | | | NFS server is restarted unconditionally when a volume option is configured through the set interface. This patch prevents restart of NFS server when operations are performed on translators that are not part of the NFS graph. This does not prevent re-start of a NFS server when an option corresponding to a translator that is part of the NFS graph is re-configured.

* glusterd: Added volume-id to 'op' dictionaryKrishnan Parthasarathi2012-04-121-0/+2
| | | | | | | | | | | | | | | | | | | | Volume-id passed in op dictionary would help detect possible split brains among peers in a cluster. The idea is to check if the volume's id and the vol-id that was passed are equal. ie, same volume name, but different volume id indicate that glusterd 'metadata' of one of the participating peers is stale or there is a split brain. This is over and above the existing checksum based validation of peer supplied cluster 'metadata' (ie, volume info file).

* glusterd: Fixed replace-brick commit_force algo.Krishnan Parthasarathi2012-03-271-1/+2
| | | | | | | | | | | | | | | | | | - commit force subcommand of replace-brick (rb) should be allowed even if source brick is (irrecoverably) offline. - modified rb_timer to be active only for start subcommand. This is important since, the rb timer event relies on src_brick and dst_brick objects to be 'alive' when it 'happens'. In the case of abort/commit/commit force it is very likely that src_brick and/or dst_brick objects could have been destroyed.

* glusterd: auth allow enhancementsRajesh Amaravathi2012-02-201-1/+23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * 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.
