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
Specific for mounting Computer Center /w areas at higher speed:
instead of line
/w auto.w.ep
insert line
/w /etc/auto_stage
and create /etc/auto_stage file containing following:
stage0 -rsize=1048576,wsize=1048576 sfs61:/export/stage stage1 -rsize=1048576,wsize=1048576 sfs56:/export/stage stage2 -rsize=1048576,wsize=1048576 sfs59:/export/stage +auto.w.ep
/etc/auto_direct (replace SunOS_sun4u by SunOS_i86pc for Opteron/Intel-based Solaris machines)
# # auto_direct # #machine-dependent system directories /apps -rw,bg clonfs1:/vol/apps/SunOS_sun4u /usr/local -rw,bg clonfs1:/vol/local/SunOS_sun4u #machine-independent system directories /mnt/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 /usr/clas -rw,bg clonfs1:/vol/clas /mnt/archives -rw,bg clonfs1:/vol/archives /mnt/logs -rw,bg clonfs1:/vol/logs #

#clon00/clon10 admin clonfs1/clonfs2 mounts /mnt/admin/clonfs2 -rw,bg clonfs2:/ /mnt/admin/clonfs1 -rw,bg clonfs1:/ /mnt/admin/clonfs1-apps -rw,bg clonfs1:/vol/apps /mnt/admin/clonfs1-archives -rw,bg clonfs1:/vol/archives /mnt/admin/clonfs1-clas -rw,bg clonfs1:/vol/clas /mnt/admin/clonfs1-clonweb -rw,bg clonfs1:/vol/clonweb /mnt/admin/clonfs1-clonwiki -rw,bg clonfs1:/vol/clonwiki /mnt/admin/clonfs1-downloads -rw,bg clonfs1:/vol/downloads /mnt/admin/clonfs1-home -rw,bg clonfs1:/vol/home /mnt/admin/clonfs1-local -rw,bg clonfs1:/vol/local /mnt/admin/clonfs1-logs -rw,bg clonfs1:/vol/logs /mnt/admin/clonfs1-mysql -rw,bg clonfs1:/vol/mysql /mnt/admin/clonfs1-scratch -rw,bg clonfs1:/vol/scratch /mnt/admin/clonfs1-work -rw,bg clonfs1:/vol/work #
It is important to run cronjobs on clon00 to access those directories occationally to keep them mounted, so Nagios can check their free space.
Solaris symbolic links
cd / ln -s /u/site site
RHEL5
/etc/auto.master: line /misc /etc/auto.misc must be there already, add 2 following lines after it
/u auto.u.bb --timeout 0 -DOSNAME=Linux-RHEL5 /w auto.w.bb -v -d -g
and comment out all other lines
/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):
cd / ln -s /u/site site mv home home.orig rm -f apps ln -s /misc/apps apps ln -s /misc/home home ln -s /misc/work work ln -s /misc/scratch scratch ln -s /usr/clas/archives/hist hist cd /usr mv local local.orig ln -s /misc/local local ln -s /misc/clas clas cd /mnt ln -s /misc/logs logs ln -s /misc/archives archives
Run /etc/init.d/autofs restart.
RHEL4
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 #
