Hi Julien, With bug 211990 = (https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D211990), the main issue was that iSCSI disks did not disconnect properly, so that = it was impossible to reconnect to them without changing the target name or = rebooting. I saw that you worked-around the disconnection issue turning off jumbo = frames. But I would have liked to keep jumbo on : many iSCSI disks to come on = this server, and also a long-distance link to another server. Thank you very much ! Ben=
