* geo-rep: Handle Config parser errorsAravinda VK2016-07-122-10/+23
| | | | | | | | | | | | | | | | | | | | | | | | | | | Python ConfigParser lib has two methods, readfp and read, it should be used as follows. readfp(open("defaults.conf")) read("custom.conf") ConfigParser.read(path) ignores any file errors, which is intentional since errors are handled while loading default config. Geo-rep uses only one config file(Session config in Master side and Template config on Slave side) so we should use readfp to avoid skipping OS errors. config.read is retained in case of `--config-set-rx` where glusterd creates new template config file.

* georep: add reset-sync-time option for session deleteMilind Changire2016-06-283-3/+39
| | | | | | | | | | | | | | | | | | | | | | | | | | | Set the stime xattr at all the brick roots to (0,0) if the argument reset-sync-time has been provided on the command-line. To avoid testing against directory specific stime, the remote stime is assumed to be minus_infinity, if the root directory stime is set to (0,0), before the directory scan begins. This triggers a full volume resync to slave in the case of a geo-rep session recreation with the same master-slave volume pair.

* geo-rep: update peers section in gsyncd confSaravanakumar Arumugam2016-05-311-3/+31
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem: Once Slave volume uuid is involved as part of a geo-rep session, it is possible to create the same geo-rep session with different (slave)host. But, it reflects default values for geo-rep configuration values originally configured for old geo-rep session. Reason is, slave host is used while saving config options in gsyncd.conf. With new slave host, it is not possible to retrieve those config values. Solution: Remove slave host related information from gsyncd.conf and have only master volume and slave volume as part of peers section. Also, during upgrade from old geo-rep session, update peers section to reflect only master volume and slave volume.

* glusterd/geo-rep: slave volume uuid to identify a geo-rep sessionSaravanakumar Arumugam2016-05-122-0/+57
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem: Currently, it is possible to create multiple geo-rep session from the Master host to Slave host(s), where Slave host(s) belonging to the same volume. For example: Consider Master Host M1 having volume tv1 and Slave volume tv2, which spans across two Slave hosts S1 and S2. Currently, it is possible to create geo-rep session from M1(tv1) to S1(tv2) as well as from M1(tv1) to S2(tv2). When the Slave Host is alone modified, it is identified as a new geo-rep session (as slave host and slave volume together are identifying Slave side). Also, it is possible to create both root and non-root geo-rep session between same Master volume and Slave volume. This should also be avoided. Solution: This multiple geo-rep session creation must be avoided and in order to avoid, use Slave volume uuid to identify a Slave. This way, we can identify whether a session is already created for the same Slave volume and avoid creating again (using different host). When the session creation is forced in the above scenario, rename the existing geo-rep session directory with new Slave Host mentioned.

* geo-rep: Fix Entry Creation issue with non root UID/GIDAravinda VK2016-03-091-0/+20
| | | | | | | | | | | | | | | | | | | | | | | During entry_ops RENAME Geo-rep sends stat info along with the recorded info from Changelog. In Slave side if Source file exists Geo-rep renames to Target file by calling os.rename. If source file does not exists, it tries to create Target file directly using available stat info from Master. If UID and GID are different in Master for that file then stat info will have different UID/GID during Create. Geo-rep gets EACCES when it tries to create a new entry using gfid-access with different UID/GID. With this patch, Entry creation with different UID/GID is split into two operations. Create Entry with UID:0 and GID:0 and then set UID/GID.

In a Tiering based volume, cold tier is hashed subvolume and geo-rep captures all namespace operations in cold tier. While syncing a file and its corresponding hardlink, it is recorded as MKNOD in cold tier(for both) and We end up creating two different files in Slave. Solution: If MKNOD with Sticky bit set is present, record it as LINK. This way it will create a HARDLINK if source file exists (on slave), else it will create a new file. This way, Slave can create Hardlink file itself (instead of creating a new file) in case of hardlink.

* geo-rep: use cold tier bricks for namespace operationsSaravanakumar Arumugam2015-12-034-17/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem: symlinks are not getting synced to slave in a Tiering based volume. Solution: Now, symlinks are created directly in cold tier bricks( in the backend). Earlier, cold tier was avoided for namespace operations and only hot tier was used while processing changelogs. Now, cold tier is HASH subvolume in a Tiering volume. So, carry out namespace operation only in cold tier subvolume and avoid hot tier subvolume to avoid any races. Earlier, XSYNC was used(and changeloghistory avoided) during initial sync in order to avoid race while processing historychangelog in Hot tier. This is no longer required as there is no race from Hot tier. Also, avoid both live and history changelog ENTRY operations from Hot tier to avoid any race with cold tier.

But with shard translator being enabled on slave, doing entry creation with MKNOD and SETATTR is not allowed, SETATTR fails as it accesses inode structure which is not linked.

* geo-rep: Avoid cold tier bricks during ENTRY operationSaravanakumar Arumugam2015-10-264-5/+30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is a series of patch 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. Now, once the file is demoted to COLD tier, any namespace operation carried out on the cold tier can be avoided as we directly RECORD the same in HOT tier. How? 1. Check whether the brick is cold tier and skip ENTRY operation. 2. Also, if it is cold tier brick, use Xsync(which is used during initial run). This will help in getting all cold tier bricks changes using File System crawl and helps in avoiding races with hot tier brick(which can happen if historychangelog used in cold tier brick).
