While we are doing these operations, contribution of + * the file/directory shouldn't be changing as we want to be sure that + * a) what we subtract from src-parent is exactly what we add to dst-parent + * b) we should subtract from src-parent exactly what we contributed to + * src-parent + * So, We hold a lock on src-parent to block any parallel transcations on + * src-inode (since that's the one which survives rename). + * + * If there are any parallel transactions on dst-inode they keep succeeding + * till the association of dst-inode with dst-parent is broken because of an + * inode_rename after unwind of rename fop from marker. Only after unwind + * (and hence inode_rename), we delete and subtract the contribution of + * dst-inode to dst-parent. That way we are making sure we subtract exactly + * what dst-inode contributed to dst-parent. + * + * 2) lookup contribution to src-parent on src-inode. + * We need to save the contribution info for use at step-8. + * + * 3) wind rename + * Perform rename on disk + * + * 4) remove xattr on src-loc + * After rename, parent can change, so + * need to remove xattrs storing contribution to src-parent. + * + * 5) remove contribution node corresponding to src-parent from the in-memory + * list. + * After rename, contri gfid can change and we have + * also removed xattr from file. + * We need to remove in-memory contribution node to prevent updations to + * src-parent even after a successful rename + * + * 6) unwind rename + * This will ensure that rename is done in the server + * inode table. An inode_rename disassociates src-inode from src-parent and + * associates it with dst-parent. It also disassociates dst-inode from + * dst-parent. After inode_rename, inode_parent on src-inode will give + * dst-parent and inode_parent on dst-inode will return NULL (assuming + * dst-inode doesn't have any hardlinks). + * + * 7) release inodelk on src-parent + * Lock on src-parent should be released only after + * rename on disk, remove xattr and rename_unwind (and hence inode_rename) + * operations. If lock is released before inode_rename, a parallel + * transaction on src-inode can still update src-parent (as inode_parent on + * src-inode can still return src-parent). This would make the + * contribution from src-inode to src-parent stored in step-2 stale. + * + * 8) Initiate mq_reduce_parent_size_txn on src-parent to remove contribution + * of src-inode to src-parent. We use the contribution stored in step-2. + * Since, we had acquired the lock on src-parent all along step-2 through + * inode_rename, we can be sure that a parallel transaction wouldn't have + * added a delta to src-parent. + * + * 9) Initiate mq_reduce_parent_size_txn on dst-parent if dst-inode exists. + * The size reduced from dst-parent and its ancestors is the + * size stored as contribution to dst-parent in dst-inode. + * If the destination file had existed, rename will unlink the + * destination file as part of its operation. + * We need to reduce the size on the dest parent similarly to + * unlink.

for listing them, -type - - gsyncd.py --help - -and see the long options up to "--config-file". (The leading double dash should be omitted; -interim underscores and dashes are interchangeable.) The set of options bear some resemblance -to those of glusterfs and rsync. - -The config file format matches the following syntax: - - <option1>: <value1> - <option2>: <value2> - # comment - -By default (unless specified by the option `-c`), gsyncd looks for config file at _conf/gsyncd.conf_ -in the source tree. - -USAGE ------ - -gsyncd is a utilitly for continous mirroring, ie. it mirrors master to slave incrementally. -Assume we have a gluster volume _pop_ at localhost. We try to set up the following mirrors -for it with gysncd: - -1. _/data/mirror_ -2. local gluster volume _yow_ -3. _/data/far_mirror_ at example.com -4. gluster volume _moz_ at example.com - -The respective gsyncd invocations are (demoing some syntax sugaring): - -1. - - gsyncd.py gluster://localhost:pop file:///data/mirror - - or short form - - gsyncd.py :pop /data/mirror - -2. `gsyncd :pop :yow` -3. - - gsyncd.py :pop ssh://example.com:/data/far_mirror - - or short form - - gsyncd.py :pop example.com:/data/far_mirror - -4. `gsyncd.py :pop example.com::moz` - -gsyncd has to be available on both sides; it's location on the remote side has to be specified -via the "--remote-gsyncd" option (or "remote-gsyncd" config file parameter). (This option can also be -used for setting options on the remote side, although the suggested mode of operation is to -set parameters like log file / pid file in the configuration file.) diff --git a/xlators/features/marker/utils/syncdaemon/__init__.py b/xlators/features/marker/utils/syncdaemon/__init__.py deleted file mode 100644 index e69de29bb2d..00000000000 --- a/xlators/features/marker/utils/syncdaemon/__init__.py +++ /dev/null diff --git a/xlators/features/marker/utils/syncdaemon/configinterface.py b/xlators/features/marker/utils/syncdaemon/configinterface.py deleted file mode 100644 index 25a2a526818..00000000000 --- a/xlators/features/marker/utils/syncdaemon/configinterface.py +++ /dev/null @@ -1,59 +0,0 @@ -try: -
