From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.0.1) Gecko/20021003 Description of problem: I just upgraded to RH9 and was suprised to see that Redhat is still using the old LVM 1.0.3 version that has known bugs in the tool set? Sistina highly recommends that all LVM 1.x users upgrade to 1.0.6. LVM 1.0.6 is fully backward-compatible and is essentially a bug fix release of LVM 1.0.3. There is really no reason not to provide LVM 1.0.6 at the very least. This is such a critical component that it should have the latest bug fixes available. Redhat, please provide an upgrade RPM for LVM to version 1.0.6 through up2date and even more preferably to LVM 2.0 if possible which has support for device mappers. Version-Release number of selected component (if applicable): kernel-2.4.20-8 How reproducible: Always Steps to Reproduce: 1.read the description 2. 3. Additional info:
If I need to choose between a slightly older LVM and an LVM that corrupts data regularly I actually prefer the slightly older LVM.
What kind of answer is that. Are you insinuating that 1.0.6 corrupts data regularly? Do you have test results to back up this assertion? If this were true then linux-lvm list would be overflowing with complaints which it isn't. I know that early on (pre 8.0) Redhat made some changes to LVM and submitted them back to Sistina. At least that's what I read. Are you referring to maybe that they didn't include the RedHat changes? The recommendation of the LVM vendor is that everyone on 1.x should be upgraded to 1.0.6 due to known bugs in previous versions. There is only one outstanding issue with 1.0.6 which has very limited chance (snapshot resizing issue) which might affect say .001% of users! They may issue a 1.0.7 to deal with it. Other than that I don't know of anything else. If you are aware of something else please be specific.
"Are you insinuating that 1.0.6 corrupts data regularly? " yes. The pvmove command for example will just eat your data if you use it on a even lightly busy partition. Sistina so far has not yet merged our fixes, nor have they submitted their updates to upstream (kernel.org) kernels to get a wider audience.
The LVM vendor (Sistina) says 1.0.6 ok except for some snapshot issues and 1.0.7 is ok (snapshot issues fixed). http://marc.theaimsgroup.com/?l=linux-lvm&m=105099920124235&w=2
Red Hat LiNUX 9 ships a lvm kernel version 1.0.5+ but the user space utils are 1.0.3. I hope to see a lvm2 + evms 2.0 into the next rhl and Advace Server 3 because the storage is the only big subject to replace SUN Solaris+veritas vxvm.
LVM2 - EVMS 2.0. That would be perfect!
2.4.23-pre1 has an update to lvm 1.0.7, maybe it's time to update user_space utils to 1.0.7 too
official 2.4.25-pre4 kernel was updated to LVM-1.0.8. time to update user space utils :-?
Thanks for the bug report. However, Red Hat no longer maintains this version of the product. Please upgrade to the latest version and open a new bug if the problem persists. The Fedora Legacy project (http://fedoralegacy.org/) maintains some older releases, and if you believe this bug is interesting to them, please report the problem in the bug tracker at: http://bugzilla.fedora.us/
