Lustre 1.6 Operations Manual

11.2.1.7 Running GSS Daemons
If you turn on GSS between an MDT-OST or MDT-MDT, GSS treats the MDT as a
client. You should run lgssd on the MDT.
There are two types of GSS daemons: lgssd and lsvcgssd. Before starting Lustre,
make sure they are running on each node:
■ OST: lsvcgssd
■
■
MDT: lsvcgssd
CLI: none
Note – Verbose logging can help you make sure Kerberos is set up correctly. To use
verbose logging and run it in the foreground, run lsvcgssd -vvv -f
-v increases the verbose level of a debugging message by 1. For example, to set the
verbose level to 3, run lsvcgssd -v -v -v
-f runs lsvcgssd in the foreground, instead of as daemon.
We are maintaining a patch against nfs-utils, and bringing necessary patched files
into the Lustre tree. After a successful build, GSS daemons are built under
lustre/utils/gss and are part of lustre-xxxx.rpm.
