We talked this over upstream, and neither of these options are recommended at the time being. --enable-bitmap-later is probably the safer of the two, but we're not sure it has the locking right and it may well cause other problems. It's also not an optional thing; if we build with that option, that behavior is always selected. --enable-fast-restart is not ready and probably never will be ready for use. It doesn't only enable a new option; it also changes the default behavior, and it probably doesn't work right. This approach is likely to be scrapped in favor of demand-attach, which is currently a work in progress in the 1.5 branch and should be stabilizing soon. I think both options at this point would trade reliability for speed, which isn't a very good tradeoff for the file server. Note that restart and salvage with 1.4.5 is, in my experience, a bit faster than it was with 1.4.4, which should help some. Also, if you haven't already, be sure to tune the parallelism of your salvager appropriately. -- Russ Allbery ([EMAIL PROTECTED]) <http://www.eyrie.org/~eagle/>
