What if I'm currently in 4.4.0 and want to upgrade to 4.4.2? Do I have to
follow the same steps as if I were in 4.4.1 or what?
I would like to avoid going through 4.4.1 if possible.
I don't think we had someone testing 4.4.0 to 4.4.2 but above procedure
should work for the same case.
The problematic filter in /etc/lvm/lvm.conf looks like:
# grep '^filter = ' /etc/lvm/lvm.conf
filter = ["a|^/dev/mapper/mpatha2$|", "r|.*|"]
Thanks,
Gianluca
