Distributed storage.
I'm pleased to announce the 12'th release of the distributed storage subsystem (DST).
DST allows to form a storage on top of local and remote nodes and combine them into linear or mirroring setup, which in turn can be exported to remote nodes.
Short changelog: * new improved mirroring algorithm. This algorithm uses sliding window approach for full resync and write log for partial resync. * fixed number of typos and debug cleanups * update inode size when linear algorithm changes the size of the storage in run time * extended number of sysfs files and documentation for them * fixed leak in local export node setup * name is 'Dancing with the smoked neutrino' now
Overall list of features of the DST can be found on project's homepage:
http://tservice.net.ru/~s0mbre/old/?section=projects&item=dst
DST is also exported as a git tree available for clone and pull from http://tservice.net.ru/~s0mbre/archive/dst/dst.git
Interested reader can test DST with 2.6.23 tree too (it should compile fine, but was not tested).
DST passed all FS tests in LTP with XFS (modulo MAX_LOCK_DEPTH too low bug: [ 8398.605691] BUG: MAX_LOCK_DEPTH too low! [ 8398.609641] turning off the locking correctness validator.
this is not DST problem though), but it was not performed with offline/online nodes.
Thank you.
