Problem: As metadata in the database fills up, querying the database
take a long time. As a result, tier migration slows down. To
counteract this, we added a way to enable the compaction methods of
the underlying database. The goal is to reduce the size of the
underlying file by eliminating database fragmentation.
NOTE: There is currently a bug where sometimes a brick will
attempt to activate compaction. This happens even compaction is already
turned on.
The cause is narrowed down to the compact_mode_switch flipping its value.
Changes: libglusterfs/src/gfdb - Added a gfdb function to compact the
underlying database, compact_db() This is a no-op if the database has
no such option.
- Added a compaction function for SQLite3 that does the following
1) Changes the auto_vacuum pragma of the database
2) Compacts the database according to the type of compaction requested
- Compaction type can be changed by changing the macro
GF_SQL_COMPACT_DEF to one of the 4 compaction types in
gfdb_sqlite3.h
It is currently set to GF_SQL_COMPACT_INCR, or incremental
vacuuming.
xlators/cluster/dht/src - Added the following command-line option to
enable SQLite3 compaction.
gluster volume set <vol-name> tier-compact <off|on>
- Added the following command-line option to change the frequency the
hot and cold tier are ordered to compact.
gluster volume set <vol-name> tier-hot-compact-frequency <int>
gluster volume set <vol-name> tier-cold-compact-frequency <int>
- tier daemon periodically sends the (new)
GFDB_IPC_CTR_SET_COMPACT_PRAGMA IPC to the CTR xlator. The IPC
triggers compaction of the database.
The inputs are both gf_boolean_t.
IPC Input:
compact_active: Is compaction currently on for the db.
compact_mode_switched: Did we flip the compaction switch recently?
IPC Output:
0 if the compaction succeeds.
Non-zero otherwise.
xlators/features/changetimerecorder/src/ - When the CTR gets the
compaction IPC, it launches a thread that will perform the
compaction. The IPC ends after the thread is launched. To avoid extra
allocations, the parameters are passed using static variables.

As part of inode_table_destroy(), we first retire entries
in the lru list but the lru_size is not adjusted accordingly.
This may result in invalid memory reference in inode_table_prune
if the lru_size > lru_limit.

socket_spawn.
Problem: Current approach to cleanup threads of socket_poller is not appropriate.
Solution: Enable detach flag at the time of thread creation in socket_spawn.
Fix: Write a new wrapper(gf_create_detach_thread) to create detachable thread
instead of store thread ids in a queue.
Test: Fix is verfied on gluster process, To test the patch followed below procedure
Enable the client.ssl and server.ssl option on the volume
Start the volume and count anon segment in pmap output for glusterd process
pmap -x <glusterd-pid> | grep "\[ anon \]" | wc -l
Stop the volume and check again count of anon segment it should not increase.
