mergemaster
On a jail created with ezjail on 10-STABLE, mergemaster is not actually ignoring files set with IGNORE_FILES in the jail's /etc/mergemaster.rc. For example: /usr/jails/whatsit/etc/mergemaster.rc IGNORE_FILES=/boot/device.hints From the host: # cd /usr/src ; mergemaster -U -D /usr/jails/whatsit ... *** There is no installed version of ./boot/device.hints Use 'd' to delete the temporary ./boot/device.hints Use 'i' to install the temporary ./boot/device.hints Default is to leave the temporary file to deal with by hand How should I deal with this? [Leave it for later] Using IGNORE_FILES=/usr/jails/whatsit/boot/device.hints in the jail does not work either. Nor does setting that value in the host's /etc/mergemaster.rc. Is this a problem with mergemaster or the jail setup? From a user standpoint, I would hope that mergemaster would read /etc/mergemaster.rc from the -D directory and use those values rather than the host's /etc/mergemaster.rc. Maybe it does that, but I'm doing it wrong. ___ freebsd-jail@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-jail To unsubscribe, send any mail to freebsd-jail-unsubscr...@freebsd.org
VNET performance
What is the expected network performance of a VNET jail for network communication between the jail and the host, or between multiple jails? I expected it to approach the 10Gbps of the epair device, but I'm not seeing that. I see between 800 - 1200 Mbps in standard iperf tests both between the host bridge interface and the vnet jail inteface. I see the same poor speeds if I make 2 vnet jails and put one side of the epair in each and test between them. Is the overhead of vnet causing this? Is there anything I can do to improve this performance. I've tested and seen similar performance on 10.0-RELEASE and 11.0-CURRENT. ___ freebsd-jail@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-jail To unsubscribe, send any mail to freebsd-jail-unsubscr...@freebsd.org

I was able to get a bit more traffic through by doing pinning games. I wonder what a vale switch for vnets could achieve. — Bjoern A. Zeeb Come on.
