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

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)

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

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
mv apps apps.orig
ln -s /misc/apps apps
ln -s /misc/home home
ln -s /misc/work work
mv scratch scratch.orig
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
ln -s /misc/clas12 clas12
cd /mnt
ln -s /misc/logs logs
ln -s /misc/archives archives 

NOTE: if some of existing directory are actual partitions mounted in /etc/fstab, you cannot remove or move them. Instead, do umount and comment out appropriate line in /etc/fstab. After that remaining directory can be moved/removed.

/etc/auto.master must looks like following (for 64bit, use -DOSNAME=Linux-RHEL5-64);

/misc   /etc/auto.misc  --timeout 60
/u      yp:auto.u.bb    -DOSNAME=Linux-RHEL5

/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

clonweb         -rw,bg     clonfs1:/vol/clonweb

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

Run /etc/init.d/autofs restart (or reload). Make sure everything is mounted. If does not, reboot the machine.

Make links to the Computer Center stuff in /usr/local area (only once when first RHEL5 machine of particular flavor is configured):

cd /usr/local/bin
ln -s /usr/local.orig/bin/jlab-linux-config jlab-linux-config
ln -s /usr/local.orig/bin/jlab-satellite-connect jlab-satellite-connect
ln -s /usr/local.orig/bin/mkdisk mkdisk
ln -s /usr/local.orig/bin/satellite_checkin.pl satellite_checkin.pl
ln -s /usr/local.orig/bin/update_crontab update_crontab
cd /usr/local/etc
ln -s /etc/motd motd
