CentOS 5.1, i686, 2.6.18-53.1.13.el5 SMP, autofs-5.0.1-0.rc2.55.el5.3.
Fully updated. Two processors. Multi-homed system (3 interfaces, DNS
reports all IP/names in both directions). Server is also a NIS master and
DNS server.
Automounting of file systems on the server is apparently going through the
NFS stack w/o a bind mount:
In /etc/auto.master:
+auto.master
In the NIS auto.master map:
/fs/home auto.home rw,rsize=32768,wsize=32768
In the NIS auto.home map:
username server-fqdn:/local/home/path/&
So, on doing a "cd /fs/home/username", we get an NFS mount:
server-fqdn:/local/home/path/username on /fs/home/username type
nfs (rw,rsize=32768,wsize=32768,addr=one-of-server-IP)
Everything works fine, but doing, for example, a large "make -j2" within
/fs/home/username results in several nfsd threads consuming approximately
80% of one CPU, and performance drops through the floor. Autofs not
recognizing the server-fqdn as the name corresponding to the primary IP on
each interface? Worked properly with autofs4. Thoughts? TIA,
