* glusterd: Fix gsyncd upgrade issueKotresh HR2016-07-151-1/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Backport of http://review.gluster.org/14898/ Problem: gluster upgrade is not generating new volfiles Cause: During upgrade, "glusterd --xlator-option *.upgrade=on -N" is run to generate new volfiles. It is run post 'glusterfs' rpm installation. The above command fails during upgrade if geo-replication is installed. This is because on glusterd start 'gsyncd' binary is called to configure geo-replication related stuff. Since 'glusterfs' rpm is installed prior to 'geo-rep' rpm, the 'gsyncd' binary used to glusterd upgrade command is of old version and hence it fails before generating new volfiles. Solution: Don't call geo-replication configure during upgrade/downgrade. Geo-replication configuration happens during start of glusterd after upgrade.

* glusterd: compare uuid instead of hostname address resolutionAtin Mukherjee2016-07-071-3/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Backport of http://review.gluster.org/14849 In glusterd_get_brickinfo () brick's hostname is address resolved. This adds an unnecessary latency since it uses calls like getaddrinfo (). Instead given the local brick's uuid is already known a comparison of MY_UUID and brickinfo->uuid is much more light weight than the previous approach. On a scale testing where cluster hosting ~400 volumes spanning across 4 nodes, if a node goes for a reboot, few of the bricks don't come up. After few days of analysis its found that glusterd_pmap_sigin () was taking signficant amount of latency and further code walthrough revealed this unnecessary address resolution. Applying this fix solves the issue and now all the brick processes come up on a node reboot.

* glusterd: copy real_path from older brickinfo during brick importAtin Mukherjee2016-05-201-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | Backport of http://review.gluster.org/14306 In glusterd_import_new_brick () new_brickinfo->real_path will not be populated for the first time and hence if the underlying file system is bad for the same brick, import will fail resulting in inconsistent configuration data. Fix is to populate real_path from old brickinfo object. Also there were many cases where we were unnecessarily calling realpath() and that may cause in failure. For eg - if a remove brick is executed with a brick whoose underlying file system has crashed, remove-brick fails since realpath() call fails. We'd need to call realpath() here as the value is of no use.Hence passing construct_realpath as _gf_false in glusterd_volume_brickinfo_get_by_brick () is a must in such cases.

| | | | | | | | | | | | | | | | | | | | | | | Backport of http://review.gluster.org/13965 glusterd_brickinfo_new_from_brick () is called from multiple places and one of them is glusterd_brick_rpc_notify where its very well possible that an underlying brick's file system has crashed and a disconnect event has been received. In this case glusterd tries to build the brickinfo from the brickid in the RPC request, however the same fails as glusterd_brickinfo_new_from_brick () fails from realpath. Fix is to skip populating real_path if its a disconnect event.

* glusterd: Replace transaction peers listsKaushal M2015-04-131-14/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Transaction peer lists were used in GlusterD to peers belonging to a transaction. This was needed to prevent newly added peers performing partial transactions, which could be incorrect. This was accomplished by creating a seperate transaction peers list at the beginning of every transaction. A transaction peers list referenced the peerinfo data structures of the peers which were present at the beginning of the transaction. RCU protection of peerinfos referenced by the transaction peers list is a hard problem and difficult to do correctly. To have proper RCU protection of peerinfos, the transaction peers lists have been replaced by an alternative method to identify peers that belong to a transaction. The alternative method is to the global peers list along with generation numbers to identify peers that should belong to a transaction. This change introduces a global peer list generation number, and a generation number for each peerinfo object. Whenever a peerinfo object is created, the global generation number is bumped, and the peerinfos generation number is set to the bumped global generation. With the above changes, the algorithm to identify peers belonging to a transaction with RCU protection is as follows, - At the beginning of a transaction, the current global generation number is saved - To identify if a peers belonging to the transaction, - Start a RCU read critical section - For each peer in the global peers list, - If the peers generation number is not greater than the saved generation number, continue with the action on the peer - End the RCU read critical section The above algorithm guarantees that, - The peer list is not modified when a transaction is iterating through it - The transaction actions are only done on peers that were present when the transaction started But, as a transaction could iterate over the peers list multiple times, the algorithm cannot guarantee that same set of peers will be selected every time. A peer could get deleted between two iterations of the list within a transaction. This problem existed with transaction peers list as well, but unlike before now it will not lead to invalid memory access and potential crashes. This problem will be addressed seprately.

* glusterd: op state machine shouldn't use global peer listAtin Mukherjee2014-10-281-0/+3
| | | | | | | | | | | | | | | | | | | | Problem : op state machine was relying on the global peer list while sending lock/stage/unlock commit rpc requests to the peers in the cluster. Trusting on global peer list structure is dangerous as this structure gets modified if any peer modification command is attempted in the cluster when there is a ongoing transaction going through the state machine. An ideal usecase of this problem when rebalance is in progress and peer probe is executed rebalance op-sm and peer probe may run into race making peerinfo structure go for toss. Solution: Use local copy of peer list (xaction_peers) in glusterd op-sm.

* glusterd: Authenticate management handshake requestsKaushal M2014-09-231-0/+3
| | | | | | | | | | | | | | | | | | | Management handshake requests, which are used to validate op-version supported by the peers, are now only allowed if, - the glusterd doesn't have any other peer, or - the request was sent by another peer. This prevents the op-version of a peer being changed because of a connection attempt by an invalid peer.

* glusterd: Prevent rebalance starting with old clientsKaushal M2014-09-031-0/+3
| | | | | | | | | | | | | | | | | Glusterd will prevent rebalance from starting when clients older than glusterfs-v3.6.0 are connected to a volume. This is needed as running rebalance with old clients connected could lead to data loss in some cases. The DHT xlator on newer clients (>= 3.6.0) has been fixed to prevent the data loss issues.

* geo-rep/glusterd: API to check active geo-rep session for the volumeKotresh H R2014-08-211-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | Requirement: Snapshot needs an API to fail the CLI if any geo-rep session is active for that volume. Solution: A function "gd_vol_is_geo_rep_active" is provided to check if any geo-rep session is active for that volume. An in memory dict called 'gsync_running_slaves' is maintained in 'volinfo' structure to keep track of active geo-rep session for the volume. The key 'slavenode::slavevol' with value 'running' is added whenever geo-rep is started/resumed into the dict and the same is removed if stopped/paused. So the 'count' in dict is used to decide whether the geo-rep is active or not for that volume. Also added "this->name" in gf_log in routines which this patch is touched.

This patch mainly does two things, 1. Extend the peerinfo object to store a list of addresses instead of a single hostname as it does now. This also includes changes to make the peer update behaviour of 'peer probe' to add to the list. 2. Improve glusterd_friend_find_by_hostname() to perform better matching of hostnames. glusterd_friend_find_by_hostname() now does and initial quick string compare against all the peer addresses known to glusterd, after which it tries a more thorough search using address resolution and matching the struc sockaddr's. The above two changes together improve the peer identification situation in glusterd a lot.
