Hi, I've tried playing with filter and global_filter in lvm.conf, but it did not help - as if the conf file was ignored. I tried blacklisting and whitelisting. Does something need to be restarted/rebooted for these settings to take effect? I then did some more experiments and eventually solved the issue. First I tried pvscan --cache /dev/md0, at which point md0 was "accepted" as existing PV, and the "system" VG would show up in vgdisplay. I was even able to resize one of the LVs. However, after running pvscan --cache with no extra agruments, I would receive the duplicate PV errors as in previous e-mail and the "system" VG would disappear from vgdisplay. :-o Finally I solved the issue by changing initcpio hook from "mdadm_udev" to "mdadm". This is arch-linux specific thing that changes stuff that is exported to the initial ramdisk used for boot. User-wise, that change would stop using udev auto-magic for assembling md arrays, but use /etc/mdadm.conf directly instead. I don't know the implementation details. After that I receive *no more errors* about either missing or duplicate PV and all VGs/LVs are displayed by the respective display commands. So for me issue is solved but if anyone wants to get to the bottom I am open to do some more experiments.
