* cluster/afr: Make local->child_up immutablePranith Kumar K2011-09-216-164/+113
| | | | | | | | | | | | | | | | | | | | | | | Afr transaction performs lock, pre-op, op, post-op and unlock steps in that order. The child_up[] is overloaded with the information of where all the first two steps succeeded. This works perfectly fine for Transaction, but the locking/unlocking part of the code is re-used by data self-heal. In that each loop_frame does lock, rchecksum, read-from-source and write-to-sinks, unlock steps. Rchecksum fop assumes that the fop needs to happen on one source + all sinks and sets the call_count to that number. But if the lock step fails on any of the sinks it will mark the child_up of that child to 0, which will result in call_count mismatch and the frame will hang thinking that some more cbks need to come. When this happens loop_frame will never go to unlock step leading to hangs on that file.

* distribute rebalance: handle the open file migrationAmar Tumballi2011-09-1217-1657/+3040
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Complexity involved: To migrate a file with open fd, we have to notify the other client process which has the open fd, and make sure the write()s happening on that fd is properly synced to the migrated file. Once the migration is complete, the client process which has open-fd should get notified and it should start performing all the operations on the new subvolume, instead of earlier cached volume. How to solve the notification part: We can overload the 'postbuf' attribute in the _cbk() function to understand if a file is 'under-migration' or 'migration-complete' state. (This will be something similar to deciding whether a file is DHT-linkfile by its 'mode'). Overall change includes below mentioned major changes: 1. dht_linkfile is decided by only 2 factors (mode(01000), xattr(trusted.glusterfs.dht.linkto)), instead of earlier 3 factors (size==0) 2. in linkfile self-heal part (in 'dht_lookup_everywhere_cbk()'), don't delete a linkfile if there is a open-fd on it. It means, there may be a migration in progress. 3. if a file's revalidate fails with ENOENT, it may be due to file migration, and hence need a lookup_everywhere() 4. There will be 2 phases of file-migration. -> Phase 1: Migration in progress * The source data file will have SGID and STICKY bit set in its mode. * The source data file will have a 'linkto' xattr pointing the destination. * Destination file will have mode set to '01000', and 'linkto' xattr set to itself. -> Phase 2: File migration Complete * The source data file will have mode '01000', and will be 'truncated' to size 0. * The destination file will have inherited mode from the source. (without sgid and sticky bit) and its 'linkto' attribute will be removed. 4. Changes in distribute to work smoothly with a file which is in migration / got migrated. The 'fops' are divided into 3 categories, inode-read, inode-write and others. inode-read fops need to handle only 'phase 2' notification, where as, the inode-write fops need to handle both 'phase 1' and phase2. The inode-write operations will be done on source file, and if any of 'file-migration' procedures are detected in _cbk(), then the operations should be performed on the destination too. when a phase-2 is detected, then the inode-ctx itself should be changed to represent a new layout. With these changes, the open file migration will work smoothly with multiple clients.

* geo-rep: partial support for unprivileged gsyncd via mountbrokerCsaba Henk2011-09-125-46/+197
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | gsyncd: - mounting code is split to a direct and a mountbroker based backend - option gluster-command gone - new options: gluster-params, gluster-cli-options, mountbroker - mountbroker mount backend is used if either a mountbroker label is given through the mountbroker option, or if gsyncd is unprivileged; in this case the username is used as label - have gluster cli invocations log to stderr so that we don't hit a permission issue with the logfiles glusterd: - do gsyncd pre-config with new options - add option geo-replication-log-group, so if that specified geo-rep logfile directories are given to that group (and thus members of the given group can do logging there) This is just WIP as geo-rep relies on trusted extended attributes and those are not accessible for unprivileged users. Even if we solved this issue, glusterd security settings are too coarse, so that if we made it possible for an unprivileged gsyncd to operate, we would open up too far.

* glusterd / cli: mount-broker serviceCsaba Henk2011-09-1213-3/+1377
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Mountbroker is configured in glusterd volfile through a DSL which is restriced enough to be able to appear in the role of the value of a volfile knob. Basically the DSL describes set-theorical requirements against the option set which is sent by the cli (in the hope of getting a mount with these options). If the requirements meet and the volume id and the uid who is to "own" the mount can be unambigously deduced from the given request, glusterd does the mount with the given parameters. The use case of geo-replication is sugared by means of volume options which then generate a complete mount-broker option set. Demo: - add the following option to your glusterd volfile: option mountbroker-root /tmp/mbr option mountbroker.fool EQL(volfile-id=pop*|user-map-root=*|volfile-server=localhost)&MEET(user-map-root=john|user-map-root=jane) - before starting glusterd, create /tmp/mbr owned by root with mode 0755 - with cli, do $ gluster system:: mount fool volfile-id=pop33 user-map-root=jane volfile-server=localhost - on succesful completion (volume pop33 exists and is started, jane is a valid username), the mount path will be echoed to you - you can get rid of the mount by $ gluster system:: umount <mount-path> Change-Id: I629cf64add0a45500d05becc3316f67cdb5b42ff BUG: 3482 Reviewed-on: http://review.gluster.com/128 Tested-by: Gluster Build System <jenkins@build.gluster.com> Reviewed-by: Vijay Bellur <vijay@gluster.com>

| | | | | | | | | | | | | | | | | | This makes client fake that given user is a superuser, by changing FUSE requests coming with uid of user so that uid is set to 0. User can be given in numeric form, in which case it's treated as an uid directly, or else it's tried to be resolved to an uid with getpwnam(3). Implies --acl.
