EVMS2 starting errors :(

trapni · Posted: Tue Aug 12, 2003 12:17 pm Post subject: EVMS2 starting errors :(

hi all,

I'm having trouble in starting EVMS2; I've the useflag evms2 enabled,
using gentoo-sources-2.4.20-r6, and have emerged evms, too.

Now starting evms by hand (/etc/init.d/evms start) or just rebooting the computer lets run me into errors.

evms (libe2fsim.1.2.1.so) complains about a different API version (8.1.0 against 10.0.0), and then it raises lots of modprobe errors (Can't locate module /dev/disc; ...). the passed modules are no modules, they're paths in my /dev directory.

Here's my booting screenshot showing it:

Many thanks for any help,
Christian Parpart.

Well I'm happy to know that I'm not alone. I have the same issue and it has something to do with devfs but the evms people didn't even seem to be able to help me. It's just something you have to live with I'm afraid. Let me know if you learn more and can get rid of the errors.

Thanks
Dolbz

well, I am using LVM (version 1) on my server right now, and would like to test EVMS (version 2) on my desktop to have a painless switch on the server side later.

But how the hell can I get into EVMS when it even doesn't start?

Damn,
Christian.

I've changed this line in /etc/evms.conf

Hi All,
I'm having just about the exact same problem.
I'm using a fresh gentoo-r6 install.
I did USE="evms2" with emerge gentoo-sources (2.4.20-r6).
Initially I did "genkernel," seems kind of cool.
After that I emerged evms (and rc-update add ...), and just to be sure I rebooted my machine. Then I did make menuconfig, changed all that I knew I would use (MD support, all the associated toys, and raid1 - my goal) to built-in, and left the rest as modules.
I'm able to run evmsn and see my devices but I can't seem to be able to do much of anything. It seems not to have properly loaded module(s).
This is the error message I get upon calling /etc/init.d/evms start:

Engine: The plug-in Ext2/3 in module /lib/evms/libe2fsim.1.2.1.so requires Engine services API version (8.1.0) which is less than this Engine's services API version (9.0.0)

This is very frusterating and I'm anxious for a fix/helpful insight.
Thank you much!

I have same problem, though I know my kernel isn't configured right yet.

Question: the evms site installation instructions have patches that need to be applied to the 2.4.x kernel for evms2 to work. Is it correct that all of these are already in the gentoo-sources kernel and so evms should work? see: http://evms.sourceforge.net/install-2.0.html Is there a list of gentoo-sources patches somewhere so I can verify this?

I see that evms 2.1.1 is out. Is there an ebuild in the works for that?

I recompiled the kernel (latest gentoo-sources) turning on options according to the evms install guide. However I didn't see options for device mapper. There is a patch for 2.4.x, but it doesn't appear to be present. Can anyone confirm this?

also, I have seen mention of the evms2 USE flag, but no official documentation of it in the USE docs. Does it really exhist and if so, what does it do?

mtPete,
I did "USE evms2" in my /etc/make.conf file . . . But this was like the first time, I wasn't usesd to using uses, so in order to be thourough (since it all seems so implicit and if emvs2 did emerge correctly you'd never see a word about it), I did "export $USE="evms2". Anyway, point being, it worked fine. Going into make menuconfig after emerging gentoo-sources (and having a good run of genkern), I found the Device mapper had installed itself - under Multi-Device Support, at the very bottom it asks to enable Device Mapper, and underneath were two or three other options (all of wich I believe _should_ be enabled).
Strangely though, before I did this "use evms2" buisness I HAD EVMS in my menuconfig - right above multi-device support. (Maybe that was after I ran some patches - which all gave copious ammounts of errors - it was late and I don't remember for sure...)
The other thing I'm wondering, like you mentioned, is weather or not the 2.0.1 ebuild (I couldn't find 2.1.1 ebuild) had the patches built in (i.e. don't worry about it or do anything) or if the files are there and meant to run (and meant to have so many errors??).

In the end I'm able to run evmsn, but if I try to do anything evms related (i.e. run evms_activate), it complains at me.

just do a rm on the library its complaining about. No worries, its safe. I already added to a bug report on this one, so look in bugs.gentoo.org if you are still confused.
