Re: reiserfs on top of md/lvm problems

["E.Gryaznova" <grev@namesys.com>]

Hello,

would you please provide the following information:
kernel version you use
# mkreiserfs -V
raid configuration file which you used to create /dev/md0
# cat /proc/mdstat
# pvs
# lvdisplay --maps
# pvdisplay -v
# vgdisplay -v
# ll /dev/mapper

Thanks,
Lena
