Bug 180220 – Xen Kernel device-mapper breaks LVM2 mirroring

• Product: Gentoo Linux
• Status: RESOLVED TEST-REQUEST

[Description orishi 2007-05-29 14:13:20 UTC]

Any attempt to work with LVM mirrors on xen-sources 2.6.16.49 will fail.
The same process works seamlessly on gentoo-sources 2.6.20-gentoo-r8


Reproducible: Always

Steps to Reproduce:
1.vgchange -a y vgstrip
 

Actual Results:  
 device-mapper: reload ioctl failed: Invalid argument
  1 logical volume(s) in volume group "vgstrip" now active
ls -d /dev/vgstrip
ls: cannot access /dev/vgstrip: No such file or directory
ls /dev/mapper/vgstrip*
/dev/mapper/vgstrip-mirrortest           
/dev/mapper/vgstrip-mirrortest_mimage_1
/dev/mapper/vgstrip-mirrortest_mimage_0




Expected Results:  
This is what I see on gentoo-sources-2.6.20 on the same machine.
ls -d /dev/vg*
/dev/vgstrip

On the system log:
device-mapper: unrecognised sync argument to mirror log: block_on_error
device-mapper: dm-mirror: Error creating mirror dirty log
device-mapper: error adding target to table

Does this still break with xen-sources-2.6.20?

Get back to us after you've tested w/ xen-sources-2.6.20-r6
