Please, I don't want to start a flamewar between filesystems. But could anybody give any recommendations to me?
I used to operate a whole bunch of Solaris systems on survey ships, and power-loss situations were always fraught. My thoughts: ReiserFS is still available and stable, why not use it for a year and see what happens? My other thought: Hardly a recommendation, because I have not tried it, but have you looked at http://jfs.sourceforge.net/ ? You could put it on an old box and pull the power cord half a dozen times to see what happens Passing thought: I've worked with instruments that use real-time linux, and most of those had a crash-proof file system of one sort or another. A bit of research into what they use might be good. I do know that Arcom use what they call "Compressed Journalling Flash File System (JFFS2)", but there are larger real-time systems with hard disks. One data acquisition system I used just used ext3 but mounted nosync. It didn't cause much trouble. Neil wrote:
Can't the systems shut down when the UPS is doing it's job? They should have enogh juice to run for a minute, or the UPS set is far below spec.
It is the obvious solution: rig the serial output from the UPS to trigger a shutdown immediately. It is possible hough that the UPS may not be large enough to provide the amps required for all those servers during normal operation. I too have worked in Banana republics and on ships where the UPS is more trouble than it is worth. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
