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:

Fix symbolic links:

Restart service:

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

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)

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
