From Bugzilla Helper: User-Agent: Mozilla/5.0 Galeon/1.2.6 (X11; Linux i686; U;) Gecko/20020913 Description of problem: I would like to see lvm2 and evms 2.0 into Advance Server 3.0 _at least_ in the first beta http://people.sistina.com/~thornber/patches/ http://evms.sourceforge.net/ Version-Release number of selected component (if applicable): How reproducible: Always Steps to Reproduce: 1.- 2.- 3.- Additional info:
Sorry, but for all intents and purposes the EVMS kernel code is dead, IBM stopped developing it so IMHO it doesn't make sense for Red Hat to try and support it. Device mapper would have been promising, except for the fact that the last dm patch for 2.4 at the URL you sent me to is from 2002-11-29 and that version has known bugs,too. This patch looks as abandoned as EVMS, at least for 2.4. I don't think it would be responsible for Red Hat to ship code in an enterprise product when that code has been abandoned by its authors. As much as I myself prefer DM over LVM1, it just wouldn't be responsible. Sorry.
rik, you go too fast :-). EVMS _1.2.xx_ is dead because alan and company don't like spaghetti kernel code,ok. This tree is frozen and only bugs fixes are made. United Linux and SuSE use it in their enterprise version. I am not telling to user this one. But EVMS >2.0.0 is _only_ a _user space tool_ based upon user-space volume discovery and communication with existing kernel drivers such as MD/Software-RAID and Device-Mapper. Not kernel code!! And it is stable and well maintained. Latest version is dated March 29, 2003 which did dm url you browse through? because I can see very recent dm code there: http://people.sistina.com/~thornber/patches/2.4-stable/2.4.20/?M=D [ ] 2.4.20-dm-10.tar.bz2 27-Mar-2003 04:18 46k and at official site has recent code too: ftp://ftp.sistina.com/pub/LVM2/device-mapper/ -r--r--r-- 1 agk ftp 275964 Mar 27 16:55 device-mapper.0.96.08.tgz Alan(cox) ships a very old version(1.0.3 2002-08-5) into .21-rc1-ac2 when the stable version is 1.0.10 2003-03-26 storage is a _real problem_ for a lot of companies that must to use Veritas VxVM+Sun_OS Solaris. It is very expensive license and the integration with Sun_OS Solaris is not easier. And a migration it is a nightmare. I think it this is one big _real_ fault to adopt linux in medium storage servers. All the people that use servers aren't hackers and they want a GUI to control the storage. Do you have more doubts?
It forgot to me: -thank you for your time-
You're making good arguments, I'll pass on your ideas to management. Note however that I cannot make any promises at this stage...
I _only_ wish if lvm2+evs2 are _stable_ at rh stress test. They should be put into the _first beta_. Because next chance is too far = 1.5 year late with AS-4 and sure with a 2.6 kernel. Or a valid option is make it sooner into a AS-3 Quarterly Update -thanks-
The kernel-2.4.20*.ent kernels for the RH AS prerelease (alpha, beta, I dunno) contain a (slightly outdated) DM driver.
more news at lvm front: LVM 2.0/Device-Mapper 1.0 available at ftp.sistina.com for kernels 2.4.20 and 2.4.21, more information: http://marc.theaimsgroup.com/?l=linux-kernel&m=105854670425970&w=2
