Re: [sarge] Some troubles with LVM2 over RAID1
Just a little tip.
Have edit the lvm.conf?
I had simular troubles but a little etrie in the lvm.conf and it runs.
# Advanced settings.
# List of pairs of additional acceptable block device types found
# in /proc/devices with maximum (non-zero) number of partitions.
# types = [ "fd", 16 ]
types = [ "device-mapper", 16 ]
types = [ "mapper", 16 ]
# By default, LVM2 will ignore devices used as components of
# software RAID (md) devices by looking for md superblocks.
# 1 enables; 0 disables.
md_component_detection = 1
Check this two opptions.
