I had a patch to use up to 256 partitions per disk independent of the type of disk. I can dig it out if anyone wants to test.

Could I get your patch? I think it would be good if this were readily
available to all.

Ahem... I forgot that you need a recompiled kernel for it to work.
Or at least arcane and forgotten commands like partx. Personally, I
like the partx way better. With the attached patch to util-linux
you can use partx.
Make sure no partition on sda is in use (swap/suspend/mounted), then
# partx -d /dev/sda
# kpartx -a /dev/sda
Now /dev/sda[1-15] have vanished and /dev/disk/by-name/sda[1-255]
appear instead. Mounting these devices works normally.
I also added this to
https://bugzilla.novell.com/show_bug.cgi?id=214992#c12

I can't put any Linux on this system because the target partition is non-negotiably sata #16 or higher. If I want to install linux anywhere I choose on a disk, I'm stuck with PATA. Windoz makes no such imposition on how I logically carve up my huge disks.
Having a maximum of 15 partitions an a SCSI disk is not a linux kernel problem, it is simply a linux kernel fact.

Exact same difference, except that the limitation when SCSI was SCSI was SCSI and not SCSI/USB/SATA/Firewire/whoknowswhatelse had a minor universe of people it affected. With the replacement of legacy ata by libata (pretending SATA is SCSI), it morphed into an artificial limitation that potentially impacts a universe several magnitudes larger. That means a solution is called for, no matter what the kernel developers say or do or not about it, or how the status quo is defined. I don't really know anything about kernel development, but if it was up to me, with the 2.8 generation of kernels, the majors and minors for PATA & SATA would be swapped to permit max 63 on SCSI and instead limit PATA to 15 unless a superior integrated system could be found and implemented. My disks average upwards of 20 partitions each, a number which continues to climb. This 24/7 system has two disks, with 43 and 18 partitions. My other 24/7 system has 1 disk with 22 partitions. There's simply no way for those numbers to be reduced as long as disk sizes keep escalating. -- "The Lord is my strength and my shield; my heart trusts in him, and I am helped."

I have no knowledge of any way LVM could do anything but increase complication. My backup strategy is heavily dependent on cloning disks and partitions across 20 machines as much as 8-10 years old having various multiboot mixtures of OS/2, DOS, doz, and Linux. -- "The Lord is my strength and my shield; my heart trusts in him, and I am helped."

Even more reason for LVM in addition to Xen/Qemu or VMware. You can consolidate your old machines into a couple of good ones and do your full disk backups with minimal downtime using the LVM tools (no downtime in some cases). That approach also allows you to light up your virtual machines immediately on any of your boxes in case one goes down. -- James Oakley jfunk@funktronics.ca --------------------------------------------------------------------- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

It's less reason, not more reason.

It's an enticing idea, but it's unworkable, and it's atithetical to the object of many copies spread among the many failure prone devices. HDs are hopelessly unreliable in the long run, and yet the best we have available. It's unworkable because a reason, among others, for having many systems, is to be able to reproduce as many hardware/OS permutations as possible. Then there's the additional complication that only one of them has sufficient RAM to support an insanely RAM hungry virtual machine environment. Lastly, I see LVM as additional complication, not simplification. Life with multiple systems is complicated enough without the addition of that extra layer, or concentrating more dependance on fewer failure prone physical devices. -- "The Lord is my strength and my shield; my heart trusts in him, and I am helped."
