With a different swap on each disk, if you loose one disk with active swap on it, you will surely crash the system. The memory on it will be lost. For the performance problem, I even use LVM for my swap ! If there is swapping, it's not normal., and performance will be bad anyway. I prefer not to swap, and to have a secured, not so speedy swap. signature.asc Description: This is a digitally signed message part.

As you can't choose on wich device your LV's PE goes, you have only 2 choice to add space. - If you want to add LVs, just make another VG with 2 new RAID 1 PVs. - If you wan't to resize actual LVs on a full VG, you have to grow the RAIDs. It's hard but I have donne it once, all online. On a SAN, it's easy to resize a LUN, but if you use disks, you'll have to replace the disks with bigger ones. > No idea if you can resize raid0 or raid1. You must use the --grow option of mdadm, and there's chances you'll have to synchronise your RAID each time one RAID is grown. If you can't replace your disks an only can add more disks, a backup/restore will be required to recreate the stripped LVs across more RAID1 PVs. Perhaps pvmove can help to switch to another VG without the backup/restore phase. signature.asc Description: This is a digitally signed message part.

From here you already can run vservers, as your Dom0 kernel is a vserver one. If you only want to have Linux vservers, no other operating systems, You don't need Xen at all ! Use linux-image-*-vserver-amd64 kernel. You you really want to mix Xen and Vservers, What I would do myself, is a light Xen Dom0 without the vserver patch, and a DomU specialized for vservers, with the vserver and xen kernel. Other DomU for other virtual machines, perhaps Windows one ore full virtuallized other distro... By not using vservers directly on Dom0, you'll keep the possibility of online migration of the Xen DomU. But, I must say, I nerver used vservers... specialy with Xen... signature.asc Description: This is a digitally signed message part.

So : Vserver is another virtualisation technologie (sort of enhanced chroot). It is not in the standard kernel, so you have à linux-image*vserver package. But, as it is not like Xen (para or full virtualization), it can be used with it. You can Have a server with several virtual machines with Xen, and in on of them (Dom0 or DomU), you can have some vservers if you use a linux-image-*-xen-vserver-*. > Also, what is the difference between xen-linux-system-2.6.18-5-xen-amd64 > and the xen-linux-system-2.6.18-5-xen-vserver-amd64 and which of these two > shall I install?

Good to know, you can change the memory allocated for a domU online ! Make some tests, load tests. If you know or you see that some tasks are slow because they can't be parallelised, add a vCPU to the domU. The essential here, is to know what your domUs will really do, and how much you planned. signature.asc Description: This is a digitally signed message part.

It is definitely a 64 bit architecture, but am not sure which > Debian distribution is the correct one for this laptop. Thanks for any > suggestions. Yes, this is the right architecture. Don't choose ia64 which is for Itanium. But, i386 will also work. Be aware that not all programs are ported to a 64bits environment. The most known of them is non-free : flashplayer.

Even with ia32-libs-gtk installed.
