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:

what next?
1k thx - e
