* distribute: Rebalance should provide even disk space distributionHarshavardhana2013-09-191-15/+30
| | | | | | | | | | | | | | | | | | | | | | | | | Earlier disk space check had an issue which didn't provide the needed functionality to avoid migration when the destination had lesser available space, scenario we need to avoid is stated below : During rebalance `migrate-data` - Destination subvol experiences a `reduction` in 'blocks' of free space, at the same time source subvol gains certain 'blocks' of free space. A valid check is necessary here to avoid errorneous move to destination where the space could be scantily available. This patch provides a proper fix in place by subtracting necessary file blocks from destination and adding those blocks to source.

* cli/glusterd: improve rebalance fix-layout status reportingRavishankar N2013-09-191-0/+2
| | | | | | | | | | | | | | | | | | | 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.

* Revert "cluster/distribute: Rebalance should also verify free inodes"Anand Avati2013-09-171-22/+5
| | | | | | | | | | | | | | | This reverts commit 215fea41a96479312a5ab8783c13b30ab9fe00fa Realized soon after merging, that this patch is actually useless. Checking for inode utilization on dst relative to src is of no use because dst is already storing linkfile and inode is already consumed no matter what. We might as well perform the rebalance and save on an inode on the src node.

* cluster/distribute: Rebalance should also verify free inodesHarshavardhana2013-09-171-5/+22
| | | | | | | | | | | | | | | | | | | | | Currently during `MIGRATE_DATA` we never verified about the total inode usage among new and old bricks. Such checks are available for disk space usage but it is also needed for inodes during data migration. Such a check leads to uniform outcome of file distribution upon rebalance. Patch provides: - Check dst_inodes < src_inodes, a friendly `warning` message to indicate we have to ignore such an attempt - Rename __dht_check_free_space() --> __dht_check_free_space_and_inodes() Change-Id: I7bc4dd8b507883f0fb836300e99f0bb083493f5f BUG: 982919 Signed-off-by: Harshavardhana <harsha@harshavardhana.net> Reviewed-on: http://review.gluster.org/5948 Tested-by: Gluster Build System <jenkins@build.gluster.com> Reviewed-by: Anand Avati <avati@redhat.com>

* dht: make DHT xattr names configurableJeff Darcy2013-03-211-14/+25
| | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | So far there has been a global glusterfs_ctx_t object which represents the running instance of the filesystem (client or server). It contains the various graphs, connection to the management daemon over which new graphs are obtained, calls stacks issued on this filesystem, and a bunch of such things. With the introduction of libgfapi, it is no more true that there will be only one filesystem context in a process. Applications can be written to use libgfapi and obtain serveral instances of different filesystems/volumes in the same process. This involves messy untangling of assumptions inside libglusterfs that there would only be one global glusterfs_ctx_t and offload that assumption to glusterfsd/ and cli/ (where it is true).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
