Hello!

The Advance Server is not free realise

2.4 kernel comes with embedded LVM (module).
2.2+ needs to build.
See here for updated LVM software:

And here how-to install etc:

LVM is supported by the Linux Kernel. Whether or not it is added to the kernel for distro of your choice???? but you can get an rpm for it.

I don't think there is a mirror-ux/type functionality in Linux.

LVM is great, I use it on HP-UX.

You can not mirror with LVM. No mirror/ux

Red Hat's Disk Druid and regualr volume management supports mirroring.

What they need to do make their built in mirroring tool integrated into LVM, then I'd switch immediately.

I am using LVM on Redhat 8.0 linux distribution
I also use Reisefs and have tryed ext3 and found it works fine and does the work in fact I mix external usb mount disk and internal scsi disk.
no problem ! plan using software raid to mirror so i can backup then split and unplug usb external disk and keep in a safe place for backup/contigency

Still some work to be done

You can download LVM from http://www.sistina.com

cat /var/log/messages | grep -i "lvm" will tell you if lvm modules are loaded, on my system this
gives

LVM version 1.0.5+(22/07/2002) module loaded

Hope some of this is usefull to you.

Actually, you can mirror LVM on Linux. The only difference is that you make the mirror first with the md driver, and then use /dev/mdX as physical volumes for your LVM environment.

Nowadays, as the price of RAID boards has dropped substancially, you can use them to replace /dev/mdX, which is software-based. Then, you'd use /dev/sda as hardware RAID 1 as PV for your VG.

Notice that neither Lilo nor Grup understand LVM partition format; thus, you'll need to make /boot as a normal /dev/sdX device. However, / and all other partitions, as well as swap, can be put into LVM.
