Description Forgotten User 7XRNh5WElB 2012-09-09 17:59:28 UTC

User-Agent:       Mozilla/5.0 (X11; Linux x86_64; rv:15.0) Gecko/20100101 Firefox/15.0

lvcreate refuses to create a mirrored logical volume

Reproducible: Always

Steps to Reproduce:
Run attached script
Actual Results:  
Can't process LV testlv: mirror target support missing from kernel?

Expected Results:  
Logical volume "testlv" created.

lvcreate's guess about missing kernel support is wrong: Creation of a mirrored device with dmsetup succeeds.

This is a regression: The attached script does not show the error with openSUSE 12.1.

I tested with openSUSE 12.2 LiveCD (KDE, final version), inside a VirtualBox hosted by openSUSE 12.1, on a x86_64 machine.

I am the llvm guy, not lvm :/

Comment 5 Thomas Fehr 2012-11-14 11:03:15 UTC

Reassigned to lvm2 maintainer

In the meantime this bug has also been reported, and fixed, in bnc#779965.

I hope I'm not exceeding my authority in marking this as a duplicate of said bug.

Comment 7 Forgotten User 7XRNh5WElB 2013-11-02 22:53:23 UTC

This bug reappeared in openSUSE 13.1.  The script in comment 1 fails in RC1 and RC2 (tested with the KDE live CD in a VirtualBox environment).  I never observed this bug in openSUSE 12.3.  Somehow I recall that the bug did not exist in early versions of 13.1 (~Milestone 3 or 4), but I'm not sure and I already deleted those images, so I can't test.

Comment 9 stefan schallenberg 2013-12-20 18:48:25 UTC

In 13.1 GA I see two results of the bug:
- Creating a LVM Volume does not work until manually loading dm_raid or dm_snapshot kernel modules
- When booting with such volumes created the volumes are not available, until the kernel modules are manually loaded (modprobe) and the LVM activation is rerun.

Seems to be a Problem that dm_* kernel modules are not loaded, whyever.

Hope this Information helps to Analyse and fix this bug.

still in final release

Comment 11 Dong Mao Zhang 2013-12-25 11:31:33 UTC

It's like bnc#779965

Can you try this:

https://build.opensuse.org/package/show/Base:System/lvm2

to see if it was fixed in factory.

Comment 12 Forgotten User 7XRNh5WElB 2013-12-25 12:04:41 UTC

Just tested (with current oS 13.1, but lvm2 package from Factory repo):
It is fixed in Factory.
