You can hugely reduce fsck's memory requirements by adjusting newfs parameters, especially increasing block size and decreasing inode density from the defaults. Consider the expected average file size and have a play with different parameters. Try it on a running system where you can send SIGINFO to the fsck process and you'll get some feedback on how far it's got. If you haven't tried adjusting this before, I think you will be very surprised at the difference it makes. If you have free RAM when the system is running you might want to look at increasing the kern.bufcachepercent sysctl (this memory isn't dedicated to buffer cache; if processes start using more memory they take it back). But further discussion along these lines should probably move to an OpenBSD list. _______________________________________________ Soekris-tech mailing list Soekris-tech@lists.soekris.com http://lists.soekris.com/mailman/listinfo/soekris-tech
