| | | | | | | | | | | | | | creating a local synctask_env can lead to creating of many more syncop threads than required. The current syncop logic can handle the scale-up/scale-down of threads depending on the load. Hence, its neater to use global synctask env.

* distribute rebalance: handle the open file migrationAmar Tumballi2011-09-121-32/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | Returning 0 times means the values are unreliable and not to be trusted for the purposes of caching. This is a temporary fix till we bring in proper times handling in DHT to return consistant values for parent inodes. Signed-off-by: Shehjar Tikoo <shehjart@gluster.com> Signed-off-by: Anand V.

| | | | | | | | | | | | | | * Added 'auto' option, older boolean options works as they used to. * This option should make 'create' rate faster, also handles self-healing of linkfile properly in case of scaling to more servers or filesystem is getting full.

| | | | | | | | | | | | | | | Now nufa uses dht_conf->private variable to store its contents, and doesn't pollute distribute's structures. It used to hang earlier as layout_lock was not INIT()'d. whitespace-cleanup done on the code too. Signed-off-by: Amar Tumballi <amar@gluster.com> Signed-off-by: Anand V.
