haha now thi sis even more wierd. Rebuild rate is at 1700K/s when my box is not loaded. When i change make flags to -j5 and compile something. The load ofcourse rises but strange thing is that rebuild rate also rises. Seems like reverse fnction of what it should :) Did 4 compiles at the same time and got the resync rate up to 6000K/s wierd. I better go buy a playstation instead ;) "Phantazm" <phantazm@xxxxxxxxxxx> skrev i meddelandet news:cv9gbc$84g$1@xxxxxxxxxxxxxxxx > My resync problem still goes on :-( > > When the resync is done on my raid5 with 8 disks just goes into a loop and > marks 2 disks as failed. > > Then i need to reboot and assemble them again with the force.
