Hi! I have a Compaq DL380 G2 server with a SmartArray 5i controller running 4.8-RELEASE.
When I move a lot of data on the disk (like untarring a new ports collection or /usr/src/) the process works fine for a while, then takes a long pause, then restarts again. When it "pauses", pressing ^T shows it's in the "wdrain" state, which looks related to waiting for the disk to finish some write operations. Unfortunately, the 5i controller has a somewhat poor performance by itself so that may be the cause. Are there any kernel tunables that I could change to at least "spread" the pauses over many small intervals, rather than locking the process for a few seconds? The volume is using softupdates, I thought about changing kern.filedelay and friends but I'd like to know if there are sensibile values to put in before I fry the production server :) -- jimmy _______________________________________________ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
