mars0.1stable52
|
||||||
|
* Major contrib: new example scripts for MARS background data
|
||||||
|
migration during production. 1&1-specific code in a separate
|
||||||
|
plugin. You can write your own plugins for adaptation to
|
||||||
|
your needs.
|
||||||
|
* Minor fix: limit the size of the writeback buffer by the
|
||||||
|
rest space in /mars. This is only relevant when
|
||||||
|
/mars is dimensioned smaller than RAM (which should
|
||||||
|
never be the case in production systems, but might happen
|
||||||
|
accidentally or for testing).
|
||||||
|
Analogously, limit the maximum logfile size.
|
||||||
|
* Minor fix: prevent creation of many tiny logfiles over time
|
||||||
|
when secondaries are not catching up.
|
||||||
|
The default threshold is a minimum of 5 GB size when more
|
||||||
|
than 10 logfiles are already present.
|
||||||
|
* Minor fix: cleanup old internal .tmp-* symlinks which might
|
||||||
|
remain as leftovers when marsadm is dying at the wrong
|
||||||
|
moment.
|
||||||
|
* Minor improvement: don't run O(n) mapfree under spinlock.
|
||||||
|
More speed improvements under preparation; will result in O(k).
|
||||||
|
* Some more minor improvements.
