Hi Neil,
This update brings:
1/ Various imsm fixes, importantly some updates due to a clarification
of how the Windows driver marks disk failures
2/ Support for handling removed disks as currently all container
manipulations fail once a live disk is hot-unplugged.
3/ An initial mdmon man page
4/ imsm auto layout support
5/ Updates to --incremental in pursuit of assembling external metadata
arrays in the initramfs via udev events
The one "fix" that is missing from this update is to teach mdmon to kick
"non-fresh" drives similar to what the kernel does at initial assembly.
I dropped the attempt after realizing I would need to take an O_EXCL
open on the container in an awkward place. I guess it is not necessary,
but it is a quirk of containers that known failed drives can be allowed
back into the container.
Thanks to Jacek Danecki and my colleagues in Poland for identifying the
removed disks problem and working through the regressions on this
release. Also along these lines you will see that I have moved
development to github to allow more collaboration on this tree.
Please have a look.
Is it about time for a -devel3 release?
Regards,
Dan
