I just had a machine fall over on my for the first time in ages - one of a pair of machine we have running hast with zfs on top. I havent got any concrete evidence of what made it die as yet, but I did notice the logifles filling up with thoursands of lines like this just prior to the crash:
serpentine-active hastd[1522]: [serp1] (primary) Remote request failed (Operation not supported): DELETE(26847744000, 1536). so I am guessing taht is ZFS trying to send a trim command to hast, and hast does not support it. Have disabled zfs trim now, but thought it was worth mentioning - I would have not expected zfs to be trying to issue a trim command to an underlying device which doesnt support it. These machines were rock solid under 8, and the only chnage I can see with 9 is the trim support being added. cheers, -pete. _______________________________________________ freebsd-stable@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "freebsd-stable-unsubscr...@freebsd.org"
