[linux-lvm] problem with vgcreate

[Robert L. Harris]

I'm trying to create a LVM for a system.  I partitioned my drives,
rebooted and do my pvcreates but then it blows up on vgcreate.  The
drives are both 18Gig, I've duplicated the partitions so they're
identicle size even though they're going to be concats, not stripes.

Here's a screen dump just made a bit readable.

root@performance:/root# pvcreate /dev/sda2
pvcreate -- physical volume "/dev/sda2" successfully created

root@performance:/root# pvcreate /dev/sdb2
pvcreate -- physical volume "/dev/sda2" successfully created

root@performance:/root# pvscan -v
pvscan -- reading all physical volumes (this may take a while...)
pvscan -- walking through all physical volumes found
pvscan -- no valid physical volumes found

performanc:/root# vgcreate -v lvm-vg1 /dev/scsi/host0/bus0/target0/lun0/part2 /dev/scsi/host0/bus0/target1/lun0/part2
vgcreate -- checking volume group name
vgcreate -- checking volume group directory existence

vgcreate -- counting all existing volume groups
vgcreate -- reading all physical volume data from disks

Any reason you use the devfs paths for the vgcreate and
devfsd for the pvcreate's?

Re: [linux-lvm] problem with vgcreate

[Robert L. Harris]

Tried them both in both combinations and neither one worked.  I got a
new error message after the last reboot about the partition type.  It
was "linux" not 8e (Unknown according to fdisk).  vgcreate is working
per below now.

Probably this bizaar hardware I'm stuck with.

Sure of that ???                               ^^^^

Just for the fun of it, if the physical volumes are still
unusable (this will wipe them out if you are using them:

	for file in /dev/sd[ab]2
	do
		dd if=/dev/null of=$file bs=1b count=1;

		pvcreate --force --verbose $file;

		pvdisplay $file;
	done

If you prefer to use devfs -- I do -- then replace
/dev/sd[ab]2 with /dev/scsi/hostX/target[01]/lun0/part2.
