Hi everyone,
This is dm-ioband version 0.0.3 release.
Dm-ioband is an I/O bandwidth controller implemented as a device-mapper driver,
which gives specified bandwidth to each job running on the same physical
device.
Changes since 0.0.2 (23rd January):
- Ported to linux-2.6.24.
- Rename the name of this device-mapper device as "ioband."
- The output format of "dmsetup table" can be recognized by "dmsetup
create/load/reload."
- Add a new feature to block processes requesting BIOs in case the number
of the uncompleted BIOs becomes too large.
- Gid can be used as an ioband group type.
- Support "dmsetup suspend --noflush."
- Fix the problem that "dmsetup detach" doesn't wait the completion of
all the BIOs in the detaching group.
- Fix the problem that "dmsetup message attach" can't accept ID 0.
- Code cleanups. Use prefix "dm_" for the global symbols.
- Add examples in the document.
Thanks,
Ryo Tsuruta
