Release Notes: The most important changes include limiting of chunkserver disconnections, a fix for network connection timeouts, a progress percentage in metarestore, and an improved algorithm for choosing servers for write new chunks.
Release Notes: The most important changes include fixed signal handling in multithreaded modules, goal and trashtime limits in mfsexport.cfg, and a simple check for downloaded metadata files.
Release Notes: The most important changes include retention of previous copies of metadata, applying new settings on "reload" (SIGHUP), and better handling of full disks on the master.
Release Notes: Chunkserver packet registration has been improved (one big packet is divided into several small ones). Also, minimum socket timeout has been set to ten seconds so that the system has time to register and the master doesn't hang up.
Release Notes: Substantial changes were introduced to the metalogger machine and metarestore tool for better integrity of the metadata. A scanning progress bar in CS was added. The master name is now resolved when a connection fails. A new session is created when the previous one is lost. Lots of other bug fixes and improvements were made.
Release Notes: Automatic data cache management and a new flag "nodatacache" were added.
Release Notes: This release added clearing of SUID/SGID bits and a check for the "sticky" flag during rename and unlink operations, fixed POSIX compatibility with removing empty directories on rename and proper changing of ctime, fixed some constants to provide better support for larger systems with millions of files and chunks, fixed error logging, fixed some OpenSolaris compilation issues (mainly by adding -D__EXTENSIONS__ to the compile flags), fixed an OpenSolaris pthreads issue, and fixed an overflow on negative time differences in hdd stats. A man page was added for mfscgiserv and "BIND" option descriptions were added to the man pages.
Release Notes: This is a maintenance release. A "double free" error was fixed for the daemons. Bugs were fixed in the "REPAIR" and "SNAPSHOT" entries for metarestore. A bug in the master "snapshot" command was fixed, in which "mfsmakesnapshot dir dir/" caused master to hang-up. Atime and mtime are preserved during the master "snapshot" operation, which makes "snapshot" work more like "cp -Rp" than "cp -R". "Marked for removal" disks are omitted by cs during chunk test loo.
Release Notes: A CRC-block and file descriptor cache was added in chunkserver. Compilation warnings on 64-bit machines were removed. The chunkserver choice in mfsmount was optimized. A better replication algorithm is used. Several bugs were fixed, mainly in the new code introduced after 1.5.9.
Release Notes: An improved rebalancing algorithm. Protections against overriding metadata.mfs.back by older metadata.mfs. Fixes to build mfstools, mfsmaster, and mfsmetarestore with Large File Support on Linux (previously only mfsmount had LFS enabled). Less verbose logging in mfsmaster. This release logs chunkserver disconnections in mfsmaster.
