Strange — that’s exactly what I did on the vagrant image, but it doesn’t fix the problem.. The symptom is that the first time a fs gets mounted it takes about 10s (presumably time for the kerberos call to time out) and then it mounts normally. On my non-vm machines (mostly mint 17), but at least one trusty system, just setting NEED_GSSD=yes in /etc/default/nfs-common did the trick, no need to blacklist the kerberos module.
But neither seems to work in the vagrant vm.. perhaps I need to double check with a stock trusty vm image not using vagrant.. /jamie On Fri, Dec 5, 2014 at 4:44 AM, Andre <1270...@bugs.launchpad.net> wrote: > I had to blacklist the module rpcsec_gss_krb5 on all Trusty machines to > get NFS working at aceptable speeds again.
