Automounts

Solaris

Solaris automounts on CLON cluster controls by following files:

/etc/auto_master

/-      /etc/auto_direct
/-      auto_direct.ep
/u      auto.u.ep
/w      auto.w.ep

/etc/auto_direct (replace SunOS_sun4u by SunOS_i86pc for Opteron/Intel-based Solaris machines)

It is important to run cronjobs on clon00 to access those directories occationally to keep them mounted, so Nagios can check their free space.

Linux

Linux automounts on CLON cluster controls by following files:

/etc/auto.master

/u      auto.u.bb    --timeout 0 -DOSNAME=Linux-RHEL4
/w      auto.w.bb -v -d  -g
/misc	/etc/auto.misc

/etc/auto.misc (replace Linux_i686 by Linux_ppc or Linux_x86_64 for corresponding machines)

#
# auto.misc
#
cd		-fstype=iso9660,ro,nosuid,nodev	:/dev/cdrom
#machine-dependent system directories
apps            -rw,bg     clonfs1:/vol/apps/Linux_i686
local           -rw,bg     clonfs1:/vol/local/Linux_i686
#machine-independent system directories
downloads       -rw,bg     clonfs1:/vol/downloads
home            -rw,bg     clonfs1:/vol/home
work            -rw,bg     clonfs1:/vol/work
scratch         -rw,bg     clonfs1:/vol/scratch
#machine-independent clas directories
clas            -rw,bg     clonfs1:/vol/clas
archives        -rw,bg     clonfs1:/vol/archives
logs            -rw,bg     clonfs1:/vol/logs
#

#clonweb only
clonweb         -rw,bg     clonfs1:/vol/clonweb

#clondb1 only
mysql         -rw,bg     clonfs1:/vol/mysql

Linux symbolic links (because of Linux automount limitations we cannot do the same as on Solaris, must use symbolic links)358-3042,

cd /
mv home home.orig
ln -s /misc/apps apps
ln -s /misc/home home
ln -s /misc/work work
ln -s /misc/scratch scratch
