Automounts

General info

To unmount stalled partition:

umount -lf /xxx/yyy

To mount /work disk from the old file server, see Clonfs1.

RHEL7_x86_64

IMPORTANT: create directory /etc/systemd/system/autofs.service.d; create file /etc/systemd/system/autofs.service.d/override.conf containing following:

[Unit]
Requires=nfs-utils.service nfs-lock.service

IMPORTANT: create directory /et or ramdisk /et on clondaqx servers !!!

Modify file /etc/auto.master, adding line

/-      /etc/auto.direct  --timeout 0

Create file /etc/auto.direct with following contents:

#
# auto.direct
#
# machine-dependent system directories
/apps                 -rw,bg     clonfs1:/vol/apps/RHEL7_x86_64
/usr/local            -rw,bg     clonfs1:/vol/local/RHEL7_x86_64
# machine-independent system directories
/home                 -rw,bg     clonfs1:/vol/home
/work                 -rw,bg     clonfs1a-old:/vol/work
/scratch              -rw,bg     clonfs1:/vol/scratch
# machine-independent clas directories
/usr/downloads        -rw,bg     clonfs1:/vol/downloads
/usr/clas             -rw,bg     clonfs1:/vol/clas
/usr/clas12           -rw,bg     clonfs1:/vol/clas12
#
/logs                 -rw,bg     clonfs1:/vol/logs
#

NOTE: For vme controller host machine (used to run 'yum' on vme controllers) mount pxelinux area:

/diskless              -rw,bg     clonfs1:/vol/diskless

Fix symbolic links:

cd /
mv apps apps.orig
mv home home.orig
mv scratch scratch.orig
mkdir apps
mkdir home
mkdir scratch
mkdir work
mkdir logs
cd /usr
mv local local.orig
mkdir local
mkdir clas
mkdir clas12
mkdir downloads
cd

Restart service:

systemctl daemon-reload
service autofs restart

NOTE: File '/etc/auto.direct' must have permissions 644 and not for example 755, otherwise automount may simply ignore it and does not mount anything - found by Kelvin 29-aug-2018 on clondaq5 running RHEL7.4.

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

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

Restart service:

svcadm restart autofs

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

#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
