Hi,
Has anyone used Lustre client as root filesystem for diskless nodes?
We have a test system in which diskless clients use lustre for their rootfs.
I saw this old mail on using Lustre as root filesystem,
https://mail.clusterfs.com/pipermail/lustre-discuss/2005-May/000702.html
Is the HOWTO document mentioned in there available someplace? Seems it
is supposed to work w/ few known problem(may be there are fixed in
recent releases)
I don't know of such a howto, but what Andreas says there is the basic
recipe. It's slightly easier in 1.6 (because there are a few less extra
pieces which must be included in the initrd) but the same basic ideas apply;
put all the modules (all the ones you need, anyway) in your initrd, get them
loaded from the init script, mount the fs in question, pivot root, and off you
go.
There are some other things you'll probably want to pay attention to, for
instance it's a bad idea if all your clients share /var/log (!) but that kind
of thing is the same as if you were netbooting using nfs or anything else; all
easily handled from your init script.
