DPM Install Checklist
If you want to be reassured that DPM has installed properly, here's a checklist of what the state of the machine should be after install.
- 1 Daemons
- 2 New Users
- 3 Filesystems
- 4 Configuration Files
After YAIM has installed DPM you should have the following daemons running:
- rfiod and ftpd running as root (head node and disk server nodes).
- dpnsdaemon, dpm, srmv1, srmv2 running as dpmmgr (head node only).
These daemons listen on the following ports (which have to be opened in your firewall):
DPM server tcp 5015 DPNS server tcp 5010 SRM server v1 tcp 8443 SRM server v2 tcp 8444 RFIO server tcp 5001 GridFTP server tcp 2811 control port GridFTP server tcp 20000 - 25000 data transfer port range
In addition, because rfio only does control on 5001, but opens data channels on arbitrary ports, all ports between DPM nodes should be open.
Daemon Utility Users
After installation there will be two new users created
dpmmgr - edguser -
dpmmgr is used as a non-priviledged user to run daemons (see above), edguser to publish the DPM's information to the site BDII.
Given the VOs are supported in the site-info.def file, the usual pool accounts will be created, e.g.,
VO New Users alice alice001 - alice050 and alicesgm atlas atlas001 - atlas050 and atlassgm cms cms001 - cms050 and cmssgm dteam dteam001 - dteam050 and dteamsgm lhcb lhcb001 - lhcb050 and lhcbsgm sixt sixt001 - sixt020 and sixtsgm
All filesystems added to the DPM should be owned by the dpmmgr user, e.g.,
# ls -ld /dpmStorage0 drwxr-xr-x 4 dpmmgr dpmmgr 4096 Jul 27 13:09 /dpmStorage0
Once files arrive in the DPM per-VO subdirectories are created mode 0770:
# ls -l /dpmStorage0 drwxrwx--- 4 dpmmgr dpmmgr 4096 Jul 27 13:09 dteam
System Configuration Files
DPM (Head Node Only)
The DPM configuration file /etc/sysconfig/dpm should exist and give the host names of the DPM and DPNS server, as well as the location of the DPMCONFIGFILE:
RUN_DPMDAEMON="yes" export DPNS_HOST=<SE_HOST> export DPM_HOST=<SE_HOST> DPMCONFIGFILE=/opt/lcg/etc/DPMCONFIG
DPNS (Head Node Only)
The DPNS configration file /etc/sysconfig/dpnsdaemon will exist containing:
RUN_DPNSDAEMON="yes" export DPNS_HOST=<SE_HOST> export DPM_HOST=<SE_HOST> DPNSCONFIGFILE=/opt/lcg/etc/DPMCONFIG
Note that the DPM and DPNS database configuration files are the same in the default YAIM install.
dpm-gsiftp (All Nodes)
Similarly for /etc/sysconfig/dpm-gsiftp
export DPM_HOST=<SE_HOST> export DPNS_HOST=<SE_HOST>
rfiod (All Nodes)
Finally, the configuration file for the rfio daemon is /etc/sysconfig/rfiod, of which the important entries are:
RUN_RFIOD="yes" export DPNS_HOST=<SE_HOST>
DPM/DPNS Database Configuration File (Head Node Only)
The database configuration file should have been created, by default in /opt/lcg/etc/DPMCONFIG
This files should contain:
The DB_NAME parameter can be used to change the database name from the default of dpm_db if necessary.
Permissions File: shift.conf
/etc/shift.conf determines the hosts which have priviledged access to certain daemon services:
On the head node, all of the RFIOD TRUST entries should list the headnode itself. The DPM and DPNS entries should list all of the disk servers:
RFIOD TRUST grid08 grid08.ph.gla.ac.uk RFIOD WTRUST grid08 grid08.ph.gla.ac.uk RFIOD RTRUST grid08 grid08.ph.gla.ac.uk RFIOD XTRUST grid08 grid08.ph.gla.ac.uk RFIOD FTRUST grid08 grid08.ph.gla.ac.uk DPM TRUST grid11.ph.gla.ac.uk grid11 grid12.ph.gla.ac.uk grid12 DPNS TRUST grid11.ph.gla.ac.uk grid11 grid12.ph.gla.ac.uk grid12
In this case grid08 is the headnode, grid11 and grid12 are disk servers.
On the disk servers the RFIOD TRUST entries should list the headnode and the disk server:
RFIOD TRUST grid08 grid08.ph.gla.ac.uk grid11.ph.gla.ac.uk grid11 RFIOD WTRUST grid08 grid08.ph.gla.ac.uk grid11.ph.gla.ac.uk grid11 RFIOD RTRUST grid08 grid08.ph.gla.ac.uk grid11.ph.gla.ac.uk grid11 RFIOD XTRUST grid08 grid08.ph.gla.ac.uk grid11.ph.gla.ac.uk grid11 RFIOD FTRUST grid08 grid08.ph.gla.ac.uk grid11.ph.gla.ac.uk grid11
