* afr: refresh inode using fstatRavishankar N2015-12-201-12/+53
| | | | | | | | | | | | | | | For fd based operations (fgetxattr, readv etc.) if an inode refresh is required, do so using fstat instead of lookup. This is because the file might have been deleted by another client before refresh but posix mandates that FOPS using already open fds must still succeed.

* features/bit-rot-stub: delete the link for bad object in quarantine directoryRaghavendra Bhat2015-12-164-2/+95
| | | | | | | | | | | | | | | | | | When the bad object is deleted (as of now manually from the backend itself), along with its gfid handle, the entry for the bad object in the quarantne directory is left as it is (it also can be removed manually though). But the next lookup of the object upon not finding it in the backend, sends forget on the in-memory inode. If the stale link for the gfid still exists in the quarantine directory, bir-rot-stub will unlink the entry in its forget or in the next failed lookup on that object with errno being ENOENT.

* tier/ctr: Correcting rename logicJoseph Fernandes2015-11-253-22/+313
| | | | | | | | | | | | | | | | | | | | | | | | | | | Problem: When a file with old_file_name and GFID_1 is renamed with a new_file_name which already exists and with GFID_2, this is what happens in linux internaly. a. "new_file_name" is unlinked for GFID_2 b. a hardlink "new_file_name" is created to GFID_1 c. "old_file_name" hardlink is unlinked for GFID_2. Well this is all internal to linux, and gluster just issues a rename system call at POSIX layer. But CTR Xlator doesn't delete the entries corresponding to the "new_file_name" and GFID_2. Thus leaving the stale entry in the DB. The following are the implications. a. Promotion are tried on these stale entries which will fail and show false results in the status of migration, b. GFID_2 Files with 2 hardlinks, which will have only one hardlink after the rename will not be promoted or demoted as the DB shows 2 entries. Solution: Delete the older database entry for the replaced hardlink Change-Id: I4eafa0872253e29ff1f0bec4283bcfc579ecf0e2 BUG: 1284090 Signed-off-by: Joseph Fernandes <josferna@redhat.com> Reviewed-on: http://review.gluster.org/12711 Tested-by: NetBSD Build System <jenkins@build.gluster.org> Tested-by: Gluster Build System <jenkins@build.gluster.com> Reviewed-by: Dan Lambright <dlambrig@redhat.com> Tested-by: Dan Lambright <dlambrig@redhat.com>

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.

* features/shard: Support geo-rep for sharded volumeKotresh HR2015-10-261-34/+70
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

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