* stripe readv_cbk: Fix stat return valuesshishir gowda2011-11-081-1/+0
| | | | | | | | | | | | | | | | | | | | | | | Workaround - If the read request, does not fall to the subvolume with the largest file size set, then we never return the correct size. This leads to clients seeing a truncated file error. The work around is to wipe stat being returned as part of read call. Problem - We were passing the stbuf returned by the first child/index, which can be different to the size/blocks returned by stat. This led to applications viewing the file as being truncated. The stbuf size needs to be the largest of all results, and blocks the aggregation from all subvolumes. (similar to stat) BUG: 3774 Change-Id: I46c53c18b2b42b1f5b86b05555bbab73bf993476 Reviewed-on: http://review.gluster.com/666 Tested-by: Gluster Build System <jenkins@build.gluster.com> Reviewed-by: Amar Tumballi <amar@gluster.com>

* support for de-commissioning a node using 'remove-brick'Amar Tumballi2011-09-135-6/+141
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>
* distribute rebalance: handle the open file migrationAmar Tumballi2011-09-1213-1651/+2898
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* cluster/dht: use GFID returned from hashed subvolumeAnand Avati2011-06-091-0/+5
| | | | | | | | | | | | | .. to perform lookups on remaining subvolumes. This way, if there is a race between two clients to 'fix' GFIDs with gfid-req, then the hashed subvolume will arbitrate and return the winner in stbuf->ia_gfid. This patch uses the returned gfid as the new gfid-req thereby preventing mismatching GFIDs on other servers due to further races.
