[linux-lvm] Re: HELP changing md-device's partition-type to LVM

[svetljo <galia st-peter stw uni-erlangen de>]

Hi i couldn't change the partition's id of the RAID but i mannaged it to
create the VG, LV and to format the LV
but when i try to mount the the LV mount segfaults  and every try to do anything
with the LV finish witth a sleep
i mean when i try to mount anything ( a partition, a CD or a LV) after the
segfault of the first ' mount -t xfs /dev/myData/Music /mnt/music '  mount
goes to sleep and do not do anything
vgdisplay says that the volume is activ
lvremove says that the volume is open and can not be removed  
do you have an idea wthat is the problem
and what can i try

the LV ( lvcreate -i3 -I4 -L26G -nMusic ) 

the VG -> myData   /dev/hdh10 /dev/md6 /dev/md7

/dev/hdh10 normal partition 14G
/dev/md6 ->  linear software RAID 14G /dev/hde6 /dev/hde12 
/dev/md7 ->  linear software RAID 14G /dev/hdg1 /dev/hdg5 /dev/hdg6 /dev/hdg12

the reason:

after trying BeOS, FreeBSD and useing windows , i was trying to switch complete
to linux without having to repartiton all the drives( i have tree )
and lose about 30G of Data + and a new instalation ( the current Data and
instalation is over a software RAID-0 other a striped  LV's  or to back up
30 Gigs of Data
