Thank you for your extensive feedback. :) I think you've done a pretty good job of showing the complications involved in putting together your own lustre kernel. It sounds gnarly. What I take away from this is the need for a vanilla kernel patchset from CFS, preferably for 2.6.18 or higher. If there is already at least the basis for a vanilla 2.6.18 patchset in the current beta, that could be the starting point for an ebuild that would be of use for a while. Its been awhile since I last tried running Lustre. Perhaps it is time I tried building a 2.6.18 lustre-ized kernel. It depends on how good the patchset provided by CFS is. I don't have the bandwidth to go through the extensive process that you did to get a working kernel. -bryan -- gentoo-cluster@gentoo.org mailing list
