Motivation

The desire was to set up a local installation of the dq2 tools, eg, dq2_get and dq2_ls. Previous setups used by the UM group did not work for a variety of reasons.

Using the local dq2* commands

Below are the complete details of the installation process. In the end, the user must do at most 3 things.

These directions updated on February 11, 2013.

There are two ways to get to the dq2 tools, using either the CVMFS installation, or our own, local installation.

• CVMFS access
  • source /usr/local/bin/setup/cvmfs_atlas.sh
  • localSetupDQ2Client
• Local installation access
  • source $DQ2_ENV/setup.sh

It is now possible to do voms-proxy-init -voms atlas (you must have a grid proxy already set up to do this) and proceed to using the dq2 tools.

Note, for some of these tools, it may be necessary to do the following:

export LCG_GFAL_INFOSYS="exp-bdii.cern.ch:2170"

By default, the LOCAL dq2- tools use our own AGLT2 site as their file source. This can be over-ridden using the argument "-L some_other_site" on the tool, eg, "dq2-ls -L BNLDISK etc". Possible values for the -L argument can be obtained using the "dq2-sources" command. This is not recommended though as the copy command selected depends on both the source and destination sites, and use of "-L" implies the specified locale is also your local locale.

The environment variable above is set up only on our interactive machines (umt3int0X.physics.lsa.umich.edu), and on personal workstations. The commands are interactive in nature, so no other machine has been enabled in this way.

Examples using the local dq2* commands

• dq2-ls M5.0029578.Default.L1TT-b00001000.ESD.v13003013
  List all files at AGLT2 in this dataset
• dq2-ls -L BNL M5.0029578.Default.L1TT-b00001000.ESD.v13003013
  List all files in this dataset assuming you are at BNL
• dq2-ls -r trig1_misal1_mc12.006535.McAtNloHww200.recon.AOD.v12000605_tid018601
  List sites that have this dataset, and indicate if the dataset is complete or incomplete
• dq2-get trig1_misal1_mc12.006535.McAtNloHww200.recon.AOD.v12000605_tid018601
  Copy all files in the dataset to the current local directory tree, without specifying the source for the files
• dq2-get -s AGLT2_SRM trig1_misal1_mc12.006535.McAtNloHww200.recon.AOD.v12000605_tid018601
  Copy all files in the dataset to the current local directory tree, specifying the source as our own dCache

Special case, BNL error

An error in copying files from BNL has been found. The symptom is that copies from BNL to AGLT2 can fail, with the following error recorded, even though dq2-ls has verified the file actually exists at BNL:

Starting transfer: lcg-cp -v --vo atlas -b -D srmv2
srm://dcsrm.usatlas.bnl.gov:8443/srm/managerv1?SFN=/pnfs/usatlas.bnl.gov/NTUP01/trig1_misal1_mc12/NTUP/trig1_misal1_mc12.005104.PythiaWenu.recon.NTUP.v13003004_tid018918_sub0999443/NTUP.018918._00387.root.1

[Errno 2] No such file or directory:

Note the mixture of "srmv2" with "managerv1?SFN" in the erring copy command. The solution (hot fix) is to use the following copy syntax, specifying the -p switch:

• dq2-get -p lcg1 datasetname

Current procedure -- December 12, 2008

The underlying software is no longer the LCG/UiTarInstall, but is the WLCG-client package installed via pacman. All software is installed on replicated afs volumes, typically mounted read-only. Installation is performed from umopt1.aglt2.org, sourcing the pacman setup:
source /afs/atlas.umich.edu/opt/pacman/setup.sh

Make sure that "opt" afs volume is mounted read/write (below).

edit setup.sh and add this line at the start of the pre-setup section:

Add these 3 lines prior to the post-setup:
DQ2_LOCAL_SITE_ID="AGLT2_DATADISK"
export DQ2_LOCAL_SITE_ID
export VOMS_PROXY_INFO_DONT_VERIFY_AC='true'

edit setup.csh and add this line at the start of the pre-setup section:

Add these 2 lines prior to the post-setup:
setenv DQ2_LOCAL_SITE_ID "AGLT2_DATADISK"
setenv VOMS_PROXY_INFO_DONT_VERIFY_AC 'true'

No other setup modification is necessary, except to define the default version.
Use the installed directory version in these commands.

rm setup.csh; ln -s 0.1.25/setup.csh setup.csh

Current procedure minus 1 -- September 1, 2008

Installation is in the afs directory /afs/atlas.umich.edu/opt/localDQ2LCG

Directions here, picked up 2 files from here, namely glite-UI-3.1.18-0.tar.gz and glite-UI-3.1.18-0-external.tar.gz (September 2008 issue). Then follow the tarball installation directions, with the following modifications.

The following files must be created:

• touch glite/yaim/etc/groups.conf
• touch glite/yaim/etc/users.conf
• touch glite/yaim/etc/wn-list.conf

The site-info.def must be modified to fit our situation. Following the unpacking of the 2 tarballs, an example can be found in .../glite/yaim/examples/siteinfo/site-info.def . Copy this. The following diff output shows the changes made at AGLT2.

Next, install the dq2 enduser tools.

# source /opt/pacman-3.24/setup.sh

# pacman -trust-all-caches -allow tar-overwrite -get http://atlas.web.cern.ch/Atlas/GROUPS/DATABASE/project/ddm/releases/pacman/cache:DQ2Clients

setup.sh and setup.csh that are created here must be modified in two ways:

• Add the initial value for the data source, ie, export DQ2_LOCAL_SITE_ID=AGLT2_UM
  • Values for this can be obtained by running the command "dq2-sources"
• Add the 32-bit python image directory to the PATH, ie, /afs/atlas.umich.edu/opt/localDQ2LCG/gLite/external/usr/bin

Early version installs -- retained only for historical reasons

The dq2 tools required a local installation of the LCG tools. The also require a java sdk installation. Both are installed in afs, in the newly created volumes

• /afs/atlas.umich.edu/opt/localDQ2LCG
• /afs/atlas.umich.edu/opt/java

So, first things first, install the java sdk in afs. Following java installation directions we pick up the file "j2sdk-1_4_2_13-linux-i586.bin"

• chmod +x j2sdk-1_4_2_13-linux-i586.bin
• cd /afs/atlas.umich.edu/opt/java
• execute the binary

This needs ~165MB of disk

If /usr/lib/libldap.so.2 does not exist, then

• yum install compat-openldap.[i386|x86_64]

Now, following the directions here, the most recent versions of the two local tar files were copied to UMich from: http://grid-deployment.web.cern.ch/grid-deployment/download/relocatable/

These were then unpacked in the afs directory created for this purpose.

• cd /afs/atlas.umich.edu/opt/localDQ2LCG
• mkdir LCG
• cd LCG
• tar -zxf [location]/gliteUI_WN-2006-10-17.tar.gz
• tar -xzf [location]/gliteUI_WN-userdeps-2006-10-17.tar.gz

Now, some setup. The following files must be created:

• mkdir glite/yaim/etc
• touch glite/yaim/etc/groups.conf
• touch glite/yaim/etc/users.conf
• touch glite/yaim/etc/wn-list.conf

Create the file site-info.def . As we have configured it, only the beginning of this file needs modification from the template version found at ./glite/yaim/examples/site-info.def

Now, install LCG:

• ./glite/yaim/scripts/configure_node ./site-info.def TAR_UI

A bug exists in srmcp. This should be fixed now, as indicated by the following diff output.

     edits to /public/LCG/d-cache/srm/sbin/srm

         <     SRM_CONFIG_PARENT=dirname $SRM_CONFIG
         ---
         >     SRM_CONFIG_PARENT=`dirname $SRM_CONFIG`

Now, nearly finished, install the dq2 commands by following the directions at https://twiki.cern.ch/twiki/bin/view/Atlas/UsingDQ2#Installation These are installed in a directory parallel to the LCG directory created above

• cd /afs/atlas.umich.edu/opt/localDQ2LCG
• mkdir dq2_enduser
• cd dq2_enduser

A localized setup script must be created to go along with this, based on the .CERN and .BNL examples copied in here. This script will reference the java installation above, and also set the actual copy command to be used. I have not been able to get srmcp to work, so instead we set an alternate command given by

• export DQ2_COPY_COMMAND='lcg-cp -v --vo atlas'
