Whoa!  I just went to sistina.com (looking for the mailing-list archives)
and thought I had it wrong, I tried sistina.org but no dice, then realised
you guys have redesigned the page!

nice job!! it looks great.

Now for my predicament: As I previously posted, I successfully built LVM
1.0.1rc1 with the Linus 2.4.9 kernel on a Guiness box (RH 7.0).

I've followed the instructions in the INSTALL file except for:

> 10. Add a "vgscan" and a "vgchange -a y" to your startup files
>     (/sbin/init.d/boot with SuSE for eg.) so that the actual volume
>     group configuration is online after each reboot.
>
>     Put a "vgchange -a n" into your shutdown script (/sbin/init.d/halt for
eg.)
>     after dismounting all filesystems.

since I'm not certain of how this is done in RedHat.  I don't know whether
the right thing is to put these commands in /etc/rc.d/rc.sysinit (probably),
/etc/rc.d/rc.local (less likely) or to create an lvm file in
/etc/rc.d/inet.d with links in the /etc/rc?.d (which runlevel to put it in?
I'm so clueless!!).

For now I've just run them manually:

# vgscan
vgscan -- reading all physical volumes (this may take a while...)
vgscan -- "/etc/lvmtab" and "/etc/lvmtab.d" successfully created
vgscan -- WARNING: This program does not do a VGDA backup of your volume
group

# vgchange -a y
vgchange -- no volume groups found

I've set the type to 8e of a couple of partitions in a couple of drives as
follows:

Disk /dev/hda: 128 heads, 63 sectors, 589 cylinders
Units = cylinders of 8064 * 512 bytes

   Device Boot    Start       End    Blocks   Id  System
/dev/hda1   *         1         5     20128+  83  Linux
/dev/hda2             6       589   2354688   8e  Linux LVM

Disk /dev/hdc: 16 heads, 63 sectors, 39870 cylinders
Units = cylinders of 1008 * 512 bytes

   Device Boot    Start       End    Blocks   Id  System
/dev/hdc1   *         1     18266   9206032+  83  Linux
/dev/hdc2         18267     39870  10888416    5  Extended
/dev/hdc5         18267     18787    262552+  83  Linux
/dev/hdc6         18788     19308    262552+  83  Linux
/dev/hdc7         19309     19829    262552+  82  Linux swap
/dev/hdc8         19830     39870  10100632+  8e  Linux LVM

although, in each instance, after "writing" the modifications I got error
messages as follows:

> Command (m for help): w
> The partition table has been altered!
>
> Calling ioctl() to re-read partition table.
> Re-read table failed with error 16: Device or resource busy.
> Reboot your system to ensure the partition table is updated.
>
> WARNING: If you have created or modified any DOS 6.x
> partitions, please see the fdisk manual page for additional
> information.
> Syncing disks.

the above looks worrisome but I've found a number of tutorials that talk
about using fdisk and all of them show the same error message without
reference to what it means... so presumably it's spurious?

anyway, then:

# pvcreate /dev/hda2 /dev/hdc8
Segmentation fault (core dumped)

yikes!

I've looked through the mailing list archives but only found:

http://lists.sistina.com/pipermail/linux-lvm/2001-August/008469.html

what next?

1k thx - e
