Re: [Bug 1270445] Re: slow NFS4 without NEED_GSSD=yes
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.

This patch removes nfs-secure.target. Instead, rpc.gssd and rpc.svcgssd start started if they appear to be needed. For rpc.gssd, this means if the file /etc/krb5.keytab exists. As the only security mechanism supported is krb5, that file must exist for rpc.gssd to be useful. Conversely, if it does exist, it seems very likely that krb5 is configured on the system an may be used for NFS. For rpc.svcgssd, it also means checking if gss-proxy might be performing the equivalent task instead. So we check if it is running, and if the kernel is able to talk to it.
