Someone seems to have copied the EVMS 1.2.x ebuild and renamed it (not a big deal), then not tested it (bad)! There are big changes, the install is no exception. I will attach an ebuild I mostly made while privately messing- around with the unstable tree. It doesn't work perfect (I was having trouble getting the optional use flags to work, so commented that out), but it gets closer than a copied ebuild! -- Daniel Mannarino Reproducible: Always Steps to Reproduce: 1. Emerge evms 2. 3. Profit! Oops, not on Slashdot... Actual Results: Erm, nothing! Expected Results: Anything! Well, installed for starters :;) Someone seems to have copied the EVMS 1.2.x ebuild and renamed it (not a big deal), then not tested it (bad)! There are big changes, the install is no exception. I will attach an ebuild I mostly made while privately messing- around with the 1.9xs. It doesn't work perfect (I was having trouble getting the optional use flags to work, so commented that out), but it gets closer than a copied ebuild! Also, someone who uses it should seriously scrutinize the init script. I haven't taken a real stab at using this stuff yet, so I haven't. However I think the ebuild should be fixed/masked ASAP. I'm still working on it though, and may have a real one later tonight. -- Daniel Mannarino thesnark@operamail.com 2003-04-05 21:41:13 0000 Created an attachment (id=10250) evms-2.0.0.ebuild (Updated ebuild) Here it is. Like I said, it's not perfect, though it should compile and not trash your system. :;) BTW, I am sorry: I seem to have double-posted the bug. -- Daniel Mannarino thesnark@operamail.com 2003-04-05 22:01:56 0000 Created an attachment (id=10252) evms-2.0.0.ebuild (Fixed ebuild, Mark II) Try this one instead, it fixes the use flags. -- Daniel Mannarino seemant@gentoo.org 2003-04-06 04:46:53 0000 evms-2 requires a different kernel patch too, I believe andreas.w.simon@gmail.com 2003-04-06 05:06:19 0000 Thanks for the ebuild, it compiled and installed fine (I am going to change from LVM to EVMS and have yet to actually test the new EVMS). Here a comment: I think the ebuild should also install the files INSTALL, INSTALL.initrd, and INSTALL.HA into /usr/share/doc/evms-2.0.0/ because they contain valuable information (for example how to setup kernel and EVMS when your rootfs is on a EVMS volume, which is what I need). andreas.w.simon@gmail.com 2003-04-06 08:02:39 0000 Two more observations: The ebuild still installs the /etc/init.d/evms script from EVMS 1 which does not work with EVMS 2. The tarball has a sample initrc script in the doc dir. With EVMS 2 it's enough to just call evms_activate or evms_deactivate. But because EVMS 2 has no longer kernel-based discovery and discovery is now done in user space, I think it would be good to have EVMS support in /etc/init.d/checkfs (i.e. an evms_activate call), just like it is already done for LVM and RAID. In my tests evms_activate segfaults during execution inside the initrd environment when used with linux-2.5.66-mm3 (I applied the 2.5.66 patches from the EVMS 2 tarball). And because my rootfs is on LVM, I can't boot. Thus I fear I can't investigate this any further. There were no helpful error messages. Maybe I look again into this when I have more time. Good luck. andreas.w.simon@gmail.com 2003-04-06 10:08:47 0000 Please ignore my comment about evms_activate segfaulting. I had very stupid bug in my initrd. tantive@gentoo.org 2003-04-07 04:13:07 0000 Ok, as I broke it i'm now going to repair it... Here's what I did so far: - Checked in the updated ebuild as -r1 and removed -r0. - Added a new init-script as evms2-init (-r1 uses this one) - Added INSTALL, INSTALL.initrd, and INSTALL.HA to DODOC. I think all that has to be done from this point on is: - EVMS support in /etc/init.d/checkfs (i.e. an evms_activate call) So far so good... andreas.w.simon@gmail.com 2003-04-07 11:01:34 0000 Shouldn't EVMS-2 be masked until there are kernels with EVMS-2 support in the Portage tree, i.e. which have the respective patches applied? EVMS-2.0.0 supports kernels 2.5.66 and 2.4.20. But so far none of those kernels works out of the box with EVMS-2, all need special patches which can be found in the EVMS tarball. And as far as I see none of the kernels currently in Portage has these patches applied. All EVMS enabled kernels in the Portage tree still need the EVMS-1.2 tools and libraries. tantive@gentoo.org 2003-04-07 16:07:48 0000 As I can see the 2.0.0-r1 has ~ in it and is masked in that way. I think the kernel ebuilds should ensure to pick the right version by adding/editing DEPEND and RDEPEND to <evms-2.0.0 . thesnark@operamail.com 2003-04-07 16:35:32 0000 Thank you ::) pfeifer@gentoo.org 2003-04-15 19:53:41 0000 please try it in combination with gentoo-sources-2.4.20-r3 which has evms 2.0 support in it by using USE="evms2". You might want to use aavm (USE="aavm") when running with evms 2.0 - also remember to read the evms2 doc in the gentoo-sources documentation or in the evms 2.0 build. This stuff is pretty new and will b0rk lvm2 - *user beware*. I'd recommend staying with 1.2.1 until this is more tested. You'll also need an initrd if you're going to have your root partition is using evms. But, anyone who wants to test this out on a development box - it is there. If using evms 2.0 ruins your system - don't say I didn't warn you or recommend that you do plenty of research first. Regards, Jay pfeifer@gentoo.org 2003-04-27 02:43:19 0000 seems the ebuild is fixed and there is support in @ least one kernel. closing.
