EVMS 2.1.1 is now available, the latest in portage is 2.1.0. 2.1.1 adds support for the 2.6 kernels, which I've seen complaints in the forums about. The 2.1.0 ebuild seems to work fine with a version bump (though you might want to change a reference to the version in the text that displays post-install). Reproducible: Always Steps to Reproduce: 1. 2. 3.
Works fine as in you tried it? None of the Gentoo kernels have support for 2.1.1, so it's not useful to put it into portage yet. It will be put in portage when there is a kernel with support for it, or when the kernel team is less overworked.
I am using 2.6.0-test6-mm1 and it seems to work fine for me (and I've never touched evms before). I just put 5 GB of data onto a reiserfs evms-mounted partition with no apparent problems. Is it supposed to just not work at all, or is it a reliability issue (which would make me rethink the wisdom of putting 5GB of junk on it...)? 2.1.0 didn't work at all in the latest 2.6 test kernels and somebody on the support team on the evms project said that 2.1 hasn't worked since somewhere in the 2.5 tree. They did comment that I had to use the v4 device mapper interface to get it to work (a kernel config option). I have no idea if it works with the 2.4 kernels or not. I don't have a 2.4 kernel with device-mapper support handy. I know when I was trying to get evms to work with 2.1.0 I searched the forums and noticed a few comments about how it wasn't working with the 2.6 kernel. I hadn't seen any resolution to this so I posted on the evms support page and got a quick response.
evms 2.1.1 works fine with all kernel 2.6 betas, now it can be added to portage tree as masked package
I added 2.1.1 and 2.2.0 today, the 2.1.1 version has a few useful patches(from the IBM guys), so if you are using 2.1.1, give it a try.
