* Revert "cluster/dht: Return success in dht_discover if layout issues"shishir gowda2013-09-241-20/+12
| | | | | | | | | | | | | | | | | | | | | | | | | This reverts commit a3e593f9f17cb1e68db97bb5a0d8074793a33964 which was bought into fix dht_layout_anomalies error handling. We still see applications error'ing out due to graph switches. To fix the above issue - We cannot heal in dht_discover, as it is a gfid based lookup, and not path based. So, returning error here would lead to app's to see failure. Also, update the layout in inode_ctx even if it has anomalies. Let subsequent heals fix the issue.

* cli/glusterd: improve rebalance fix-layout status reportingRavishankar N2013-09-191-0/+4
| | | | | | | | | | | | | | | | | | | Problem: Currenly the CLI rebalance status command output does not indicate the 'type' of rebalance, i.e. whether a full rebalance or only a fix-layout was carried out. Fix: After the rebalance status of all peers is received by the originator glusterd, alter it to reflect the type of rebalance before passing it on to the CLI process.

In few cases, if dht has only 1 subvolume, and access fails with ENOTCONN, we go into a infinite loop of winding to same subvol The fix is to check if we previously wound to same subvol, and fail if first-up-subvol is same.

* glusterfs: discard (hole punch) supportBrian Foster2013-06-131-0/+2
| | | | | | | | | | | | | | | | Add support for the DISCARD file operation. Discard punches a hole in a file in the provided range. Block de-allocation is implemented via fallocate() (as requested via fuse and passed on to the brick fs) but a separate fop is created within gluster to emphasize the fact that discard changes file data (the discarded region is replaced with zeroes) and must invalidate caches where appropriate.

* dht: make DHT xattr names configurableJeff Darcy2013-03-211-6/+11
| | | | | | | | | | | | | | | | | | | | This is necessary to support "DHT over DHT" configurations, so that the upper and lower instances of DHT don't step all over each other. Why would we even consider such a thing? Because it gives us the ability to do data tiering and rack-aware placement, either by themselves or as complements to other functionality such as erasure codes or deduplication which save space but cost performance. By setting up the top-level DHT to place data into one of several lower-level DHT pools based on policy instead of pure elastic hashing, we get better performance for 90% of accesses and better storage efficiency for 90% of data, all for relatively low effort.

* cluster/dht: pathinfo xattr changes for directoriesVenky Shankar2013-02-081-0/+1
| | | | | | | | | | | | | | | | | | | | Since directories have presence on all subvolumes there is no definite meaning of ->hashed_subvol or ->cached_subvol. getxattr() code path chooses ->cached_subvol for pathinfo extended attribute. While this makes sense of files, it makes less sense for directories. Further if a hashed or a cached subvolume is down, and there's a getxattr request for a directory, we return with an errno. This patch changes pathinfo extended attribute contents by aggregating information from all subvolumes that are up.

In cases where all the subvols have lesser than Min_free_disk available , the one with max space and atleast one inode is available. Known Issue: Cannot ensure that first file that is created right after min-free-value is crossed on a brick will get created in other brick because disk usage stat takes some time to update in glusterprocess.

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.

* distribute rebalance: handle the open file migrationAmar Tumballi2011-09-121-82/+331
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
