Thanks for this, Carlos. I think it might be better to just state plainly that it overrides automatic stripe unit detection, and leave the tuning / performance parts out. Most of the manpage today is more "what" than "why." So maybe simply: +This option disables automatic stripe geometry detection, and creates +the filesystem without stripe geometry even if the underlying storage +device reports this information. FWIW, there is a 'noalign' option for the realtime subvolume as well, and that should probably get documented too. -Eric > .RE > .TP > .B \-f > _______________________________________________ xfs mailing list xfs@xxxxxxxxxxx http://oss.sgi.com/mailman/listinfo/xfs
