New DST release: Succumbed to live ant.

This is a maintenance release only and it contains only following change:

  • do not allocate big enough address structure on the stack during local export node initialization
Great thanks to Serge Leschinsky and Konstantin Kalin for testing.

As usual one can get the latest version from project homepage or via git tree.

Some problems compiling on a 2.6.23 kernel, im using a debian unstable distro.

CC [M] drivers/block/dst/dcore.o drivers/block/dst/dcore.c: In function ‘dst_sys_init’: drivers/block/dst/dcore.c:1597: error: too many arguments to function ‘kmem_cache_crea

That's because I still use 2.6.22 :)

I'm sorry, but it's impossible to send you the testing results

----- The following addresses had permanent fatal errors ----- <johnpol@xxx.mipt.ru> (reason: Can't create output)

I kicked admin and fixed this stuff by hands, thanks a lot for pointing!

Hi,

Is it possible to use dst in synchronous mode for alg_mirror ?

I mean, a write to the dst-device only returns once all mirrored nodes also performed the write (except perhaps if a node is down).

Not yet, barriers are not supported in dst, it is in todo list, but not with a high priority, iirc no other multiple device mappers (except drbd) support barriers.

Thanks, I did not get it from the TODO list.

I hope your illness is now part of the past, good devel blogs are not so common ;)

Thanks :) I think I'm about to be ready to start active hacking again, although I have not yet finished watching all 4 seasons of 'House M. D.' :)

DST currently has two opened bugs reported to me which I will fix asap when I get access to hardware to test patches on. I expected it to arrive previous week, but that did not happen, so expectation moved to March 8-15. Per-project todo lists are not published in the main one on top of the page, that is usually only for major projects.
