Hi all -
I'm trying to set up MythTV on an Ubuntu 6.06 (Dapper) box with two SATA drives. The partitions to be used for storing the video files are /dev/sda13 (approx. 250GB) and /dev/sdb1 (300GB).
Those partitions are set up as type 8e (Linux LVM). I have tried fromatting them as ext3 and jfs with the same results. The format goes fine, I can create the physical volumes with pvcreate, but then trying to create the volume group with vgcreate fails:
The first partition:
Code:
root@vader:/etc/default# pvcreate -vv /dev/sda13
File descriptor 3 left open
File descriptor 5 left open
File descriptor 7 left open

So far, so good. The second partition:
Code:

File descriptor 5 left open
File descriptor 7 left open

Again, so far, so good. Now:

File descriptor 3 left open
File descriptor 5 left open
File descriptor 7 left open

vgcreate /dev/sda13 not identified as an existing physical volume
vgcreate Unable to add physical volume '/dev/sda13' to volume group 'myth_disks'.
vgcreate Wiping internal VG cache
OK; pvcreate said both physical volumes were created, but vgcreate won't add the first volume. The same thing happens if I simply give it /dev/sdb1 as the only volume to add.
Can anyone see what I'm doing wrong here? I looked on Ubuntuforums but didn't find anything useful over there.
Thanks in advance --
Bob
