Metadata data operation are a. setattr: explicit changing of atime/mtime using utimes, changing of posix permissions of the file b. rename: Renaming a file, c. unlink, link: adding or deleting hardlinks d. xattrs: setting or removal of xattrs. NOTE: atime, mtime and ctime change through writev, readv, truncate, mknod and create will not be considered here as these fops are data and primary metadata fops. Defaultly "ctr-record-metadata-heat" is off. Admin can switch it on using gluster volume set command.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | GEO-REP INTEROP WITH SHARD FEATURE Problem: Geo-replication uses setxattr interface of gfid-access xlator to create entries and send explicit setattr after entry creation to set uid and gid. But between entry creation and setattr, the inode would not be linked. Hence operation which accesses inode structure during setattr by any the below xlator fails. Solution: Linking inode would seem the obvious solution but, gfid-access xlator cannot link inodes and maintain it as it would result in same inode pointing to two different paths one being virtual .gfid/<gfid> path and other being actual path. The solution is to set uid and gid in frame->root->uid and frame->root->gid respectively from which posix extracts and sets.

* tier/libgfdb: Replacing ASCII query file with binaryJoseph Fernandes2015-11-062-11/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Earlier, when the database was queried we used to save all the queried records in an ASCII format in the query file. This caused issues like filename having ASCII delimiter and used to take a lot of space. The tier.c file also had a lot of parsing code. Here we changed the format of the query file to binary. All the logic of serialization and formating of query record is done by libgfdb. Libgfdb provides API, gfdb_write_query_record() and gfdb_read_query_record(), which the user i.e tier migrator and CTR xlator can use to write to and read from query file. With this binary format we save on disk space i.e reduce to 50% atleast as we are saving GFID's in binary format 16 bytes and not the string format which takes 36 bytes + We are not saving path of the file + we are also saving on ASCII delimiters. The on disk format of query record is as follows, +---------------------------------------------------------------------------+ | Length of serialized query record | Serialized Query Record | +---------------------------------------------------------------------------+ 4 bytes Length of serialized query record | | -------------------------------------------------| | | V Serialized Query Record Format: +---------------------------------------------------------------------------+ | GFID | Link count | <LINK INFO> |..... | FOOTER | +---------------------------------------------------------------------------+ 16 B 4 B Link Length 4 B | | | | -----------------------------| | | | | | V | Each <Link Info> will be serialized as | +-----------------------------------------------+ | | PGID | BASE_NAME_LENGTH | BASE_NAME | | +-----------------------------------------------+ | 16 B 4 B BASE_NAME_LENGTH | | | ------------------------------------------------------------------------| | | V FOOTER is a magic number 0xBAADF00D indicating the end of the record. This also serves as a serialized schema validator.

* features/changelog: record mknod if tier-dht linkto is setSaravanakumar Arumugam2015-10-271-2/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is a series of patches which aims to fix geo-replication in a Tiering Volume. Problem: Consider, a file is placed in volume initially and then hot tier is attached. During any operation on the file, due to lookup a linkto file is created in hot tier. Now, any namespace operation carried out on the file is recorded in both cold and hot tier. There is a room for races when both changelogs are replayed. Solution: So, We are going to replay (namespace related)operations only in the hot tier. Why? a. If the file is directly placed in Hot tier, all fops will be recorded in HOT tier. b. If the file is already present in Cold tier, and if any fop is carried out, it creates linkto file in Hot tier. Now, operations like UNLINK, RENAME are captured in Hot tier(by means of linkto file). This way, we can get both tier's operation in HOT tier itself. But, We may miss initial Data sync immediately after creating the file as it is only recording MKNOD. So, if MKNOD encountered with sticky bit set, queue DATA operation for the corresponding gfid. ( This geo-rep related changes are addressed in this patch: http://review.gluster.org/12326/ ) So, If tier-dht linkto is set, we need to record the corresponding MKNOD. Earlier this was avoided as it was set as INTERNAL fop.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Approach: Shard xlator on slave side is by passed for all the fops to geo-rep mount. So each shard on master is considered as a separate file for geo-rep and it syncs them separately on to slave. The extended attribute in which shard maintains the size is also synced from master and shard on slave doesn't calculate by itself. Pre-requisites: 1. If master is sharded volume, slave also should be sharded. 2. Slave's shard configurations should be same as master. 3. Geo-rep config of xattr sync should not be disabled.

The performant approach is record the hardlinks on a compressed datastore and then do the namelookup asynchronously later, giving the ctr db eventual consistency Change-Id: I4ffc337fffe7d447804786851a9183a51b5044a9 BUG: 1252586 Signed-off-by: Joseph Fernandes <josferna@redhat.com> Reviewed-on: http://review.gluster.org/11828 Tested-by: Gluster Build System <jenkins@build.gluster.com> Reviewed-by: Dan Lambright <dlambrig@redhat.com> Tested-by: Dan Lambright <dlambrig@redhat.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | version less than 3.7 i.e rhel 6.7 Problem: On RHEL 6.7, we have sqlite version 3.6.2 which doesnt support WAL journaling mode, as this journaling mode is only available in sqlite 3.7 and above. As a result we cannot have to progreses concurrently accessing sqlite, without running into db locks! Well WAL is also need for performace on CTR side. Solution: This solution is to use CTR db connection for doing queries when WAL mode is absent. i,e tier migrator will send sync_op ipc calls to CTR, which in turn will do the query and create/update the query file suggested by tier migrator. Pending: Well this solution will stop the db locks but the performance is still an issue for CTR. We are developing an in-Memory Transaction Log (iMeTaL) which will help boost the CTR performance by doing in memory udpates on the IO path and later flush the updates to the db in a batch/segment flush.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | We've been lucky that we haven't had any symbol collisions until now. Now we have a collision between the snapview-client's svc_lookup() and libntirpc's svc_lookup() with nfs-ganesha's FSAL_GLUSTER and libgfapi. As a short term solution all the snapview-client's FOP methods were changed to static scope. See http://review.gluster.org/11805. This works in snapview-client because all the FOP methods are defined in a single source file. This solution doesn't work for other xlators with FOP methods defined in multiple source files. To address this we link with libtool's '-export-symbols $symbol-file' (a wrapper around `ld --version-script ...` --- on linux anyway) and only export the minimum required symbols from the xlator sharedlib. N.B. the libtool man page says that the symbol file should be named foo.sym, thus the rename of *.exports to *.sym. While foo.exports worked, we will follow the documentation. Signed-off-by: Kaleb S.

| | | | | | | | | | | | | | | | | | | | | | | | | | During a DHT re-balance operation, quota accounts for the destination. Problem of accounting this destination file are: 1) Migration is an internal operation, 'quota list' shows more usage on the CLI and this will come to the normal numbers once the migration is complete 2) If the usage is close to the limit set, then we can get 'Disk Quota Exceeded' errors in the I/O path during file migration Solution is we should not account of the usage on the destination file during migration, at the end of the migration. We need to reduce size of the source directory and accounting for the migrated dest file We assume that there are sufficent disk space in the back-end. DHT migrator should make sure that there are sufficient disk space before it starts the migration process.

Over time we should be able to "lower" these into .c files, but that has to be done in a case-by-case fashion requiring more manual effort.
