Hello, I've got a machine that ought to be capable to run it's tasks completely in RAM for long times (more detailsbelow). free usually reports 30-40MB (out of 80) not even to be used for buffers. Now, I thought there is a way to force the machine to fill it's buffers until either a) the disk's up anyway or b) it runs out of memory. Furthermore, I thought noflushd would be taking care of this.
the command used: noflushd -n15 /dev/hda trying to check it with -vd, I get the following: Error: no valid timeout for /dev/hda Now I wonder what I'm doing wrong. Even more as the disk actually spins down frequently, but comes back to live every couple of minutes. Thats bad, is it? More details and further ideas: It is a more-or-less classical dial-in box. It has a harddisk that from time to time is actually needed, but most of the time (approx 22hrs a day) its sole job is IP maquerading and running a nameserver (BIND9 as out of the box, caching-only). ls -rt indicates that syslogd & al. are responsible for the frequent activity, at any rate the only files that have changed during the last couple of hours are to be found in /var/log. Now, I don't want to live without logging, but consider to move the logfiles into a ramdisk and have logrotate copy them onto the disk. But this seems to be quite an endeavour, and if anyone can think of an easier way, please let me know. cu, Schnobs
