There is currently a bug with the tty char device access via lustre, but using e.g. devfs or other pseudo filesystem for /dev avoids this problem for now. That bug is under investigation.

Hi, Andreas Dilger:
Could you tell me the details using lustre as
root? Such as instructions, files and so on?
Thanks very much.

Such as instructions, files and so on?Sorry, as yet I don''t have details on this myself, but in the next month or two we will make a HOWTO document for it. The basic idea is that you need to make a rather large initrd or initramfs and put in the Lustre modules, then use zconf mount to do the mount so you don''t need all of the python environment to use lconf (llmount is what "mount -t lustre" calls): llmount {mdsnode}:/{mdsname}/{client} /mnt then pivot into the new root filesystem, mount e.g. devfs or udevfs on /dev, /proc, etc as you would with any initrd filesystem. That kind of info would be in all kinds of initrd HOWTO documents. The only special thing for Lustre is that a) you need all of the Lustre modules and llmount, b) you need /etc/modules.conf (or manually load the lustre modules in the init script (libcfs, portals, ksocknal, obdclass, etc).> --- Andreas Dilger <adilger@clusterfs.com> wrote: > > > On May 04, 2005 19:54 -0700, Tad Lake wrote: > > > Can lustre-1.4.0 as root when a client booting? > > > Is anybody try it?
