About

This page provides guidance for Virtual Organisations (VO) of the European Grid Infrastructure (EGI) on how to use the Globus Online service that is available at http://www.globusonline.eu. The services provides robust and easy to use file transfer capabilities for EGI users. Globus Online manages file transfers for you, monitoring performance, retrying failures, auto-tuning and recovering from faults automatically where possible, and reporting status. The Cookbook demonstrates how SRM storages of EGI could be used as endpoints for file transfers in Globus Online.

The Cookbook consists of two parts:

The first part provides step-by-step instructions for VO Managers on how to register SRM storage services in Globus Online in such a way, that these appear as endpoints that VO members can find and use for file tranfers. Although these steps could be performed by any member of a VO, we assume that for most VOs the VO Manager is the most suitable person to complete the steps, because the VO Managers have sufficient knowledge on storage sites of the VO and about using the BDII information system to obtain detailed information about these storages.

The second part provides step-by-step instructions for VO members on how to use storage endpoints in Globus Online. These steps can be carried out by any VO member.

The "lsgrid" VO is used as an example in the Cookbook to demonstrate Globus Online usage.

Please email any feedback about this Cookbook to the EGI.eu User Community Support Team: ucst@egi.eu.

VO Managers

All commands are performed from the command line of a gLite User Interface (UI). The "lsgrid" VO is used as an example.

1. Find storage elements available for your VO:


-bash-3.2$ lcg-infosites --is bdii.grid.sara.nl --vo lsgrid se

Avail Space(kB)  Used Space(kB)  Type     SE

------------------------------------------

      717032688       382478939  SRM      se.grid.rug.nl

    17542103037       460842863  SRM      se.lsg.hubrecht.eu

    16560797796      1442148104  SRM      se.lsg.psy.vu.nl

    58680692895             n.a  SRM      srm.grid.sara.nl

    14994733204         5266796  SRM      srm.grid.sara.nl

            n.a             n.a  SRM      srm.grid.sara.nl

Our tests with Globus Online were successful with DMP and dCache type of SRM storages, however the same process may work with some Storm storages (Storm is the third SRM storage type in use in EGI). With this query you can find out the type of the SRM storage that support your VO (GlueSEUniqueID=<SE_hostname>):


-bash-3.2$ ldapsearch -LLL -h bdii.grid.sara.nl -p 2170 -x -b mds-vo-name=local,o=grid '(&(objectClass=GlueSE)(GlueSEUniqueID=se.grid.rug.nl))' GlueSEImplementationName

GlueSEImplementationName: dCache

-bash-3.2$ ldapsearch -LLL -h bdii.grid.sara.nl -p 2170 -x -b mds-vo-name=local,o=grid '(&(objectClass=GlueSE)(GlueSEUniqueID=se.lsg.hubrecht.eu))' GlueSEImplementationName

GlueSEImplementationName: DPM

2. Find the SRM endpoint for chosen storage element:


-bash-3.2$ lcg-info --list-service --bdii ldap://bdii.grid.sara.nl:2170 --vo lsgrid --query 'ServiceType=SRM' --attrs 'ServiceEndpoint'| grep srm.grid.sara.nl

- Service: httpg://srm.grid.sara.nl:8443/srm/managerv2

 - ServiceEndpoint     httpg://srm.grid.sara.nl:8443/srm/managerv2

3. Find your VO home directory path for the SRM endpoint:

(This is the path of the directory where VO users can write files.)


lcg-info --list-se --bdii ldap://bdii.grid.sara.nl:2170 --vo lsgrid --query 'SE=srm.grid.sara.nl' --attrs 'VOInfoPath'

- SE: srm.grid.sara.nl

 - VOInfoPath          /pnfs/grid.sara.nl/data/lsgrid

4. Find the GridFTP endpoint that belongs to this SRM endpoint:


-bash-3.2$ touch test
-bash-3.2$ srmcp -2 file:///test srm://srm.grid.sara.nl:8443/pnfs/grid.sara.nl/data/lsgrid/test -debug
-bash-3.2$ lcg-gt srm://srm.grid.sara.nl:8443/pnfs/grid.sara.nl/data/lsgrid/test gsidcap
-bash-3.2$ gsidcap://bee33.grid.sara.nl:22128/pnfs/grid.sara.nl/data/lsgrid/test

5. Go to http://www.globusonline.eu/

a) Create an account with your VO name e.g. lsgrid. (Note that usernames can include only letters and numbers. The name of your VO may need to be altered!)

b) Go to "Manage Endpoints" and click "Add Endpoint".

c) Filling the endpoint details:


Name lsgrid# < enter name of the Storage >  (e.g. SARA)

Short Description: < enter description > (add VO default path for this storage, e.g. /pnfs/grid.sara.nl/data/lsgrid/)

Server Address gsiftp:// < storage hostname with GridFTP access > (e.g. bee51.grid.sara.nl)

Visible To: Anyone (public)

      

Set the Identity Provider to be used with this endpoint.

Type: MyProxy

MyProxy Hostname: < myproxy server for your VO > (e.g. px.grid.sara.nl)

VO Members

Commands are performed from the command line of a gLite User Interface (UI). The "lsgrid" VO is used as an example.

1. Generating credentials.

Generate VOMS proxy:


-bash-3.2$ voms-proxy-init --voms lsgrid

Enter GRID pass phrase:

Your identity: /O=dutchgrid/O=users/O=egi/CN=Karolis Eigelis

Creating temporary proxy .............................................................................................................. Done

Contacting  voms.hellasgrid.gr:15004 [/C=GR/O=HellasGrid/OU=hellasgrid.gr/CN=voms.hellasgrid.gr] "lsgrid" Done

Creating proxy ............................................................ Done

Your proxy is valid until Fri Nov  2 02:16:10 2012

Upload VOMS proxy to MyProxy.


-bash-3.2$ myproxy-init --voms lsgrid

Enter GRID pass phrase:

Your identity: /O=dutchgrid/O=users/O=egi/CN=Karolis Eigelis

Creating temporary proxy ............................. Done

Contacting  voms.hellasgrid.gr:15004 [/C=GR/O=HellasGrid/OU=hellasgrid.gr/CN=voms.hellasgrid.gr] "lsgrid" Done

Creating proxy ........................................... Done

Your proxy is valid until Thu Nov  8 14:17:47 2012

verify OK

Enter MyProxy pass phrase:

Verifying - Enter MyProxy pass phrase:

A proxy valid for 168 hours (7.0 days) for user karolise now exists on px.grid.sara.nl.

2. Go to to http://www.globusonline.eu/

a) Create account for yourself

b) Go to "Manage Endpoints" and click "View All".

c) Search for your VO name e.g. lsgrid

You could see something like:


lsgrid#SARA     activate

d) Click on "activate"

Fill in the details for your credentials to retrieve.


MyProxy Server: < myproxy server you have credentials at > (e.g. px.grid.sara.nl)

Username: < your user on a myproxy machine > (e.g. karolise)

Passphrase: < you chosen password > (e.g. You used to Enter MyProxy pass phrase in step 1.)

e) Click "Authenticate"

f) Go to "Start Transfer"

Choose your endpoint which is: lsgrid#SARA

Look for your VO path directory in the endpoint description: /pnfs/grid.sara.nl/data/lsgrid/

That is it. Now using Globus Online you can access Storage Element in EGI which is used also by SRM and FTS.

What you can do ?

Transfer files from your laptop using GlobusConnect client to SRM storage endpoint in EGI using GO.

Transfer files from SRM endpoint in EGI using GO to your laptop using GlobusConnect client.

Transfer files from one SRM endpoint in EGI to another SRM endpoint in EGI or to any other Infrastructure using GO and receive nice notifications by email

Additional materials

Tests have been carried out while creating this Cookbook: GO_testing

This page is a summary of the tests that Karolis Eigelis from the EGI User Community Support Team (UCST) carried out with the European Globus Online service during October-November 2012.

The tests helped UCST establish a Globus Online Cookbook for EGI Virtual Organisations. Other results of the tests are a number of conclusions:

Because of lack of regulations, restrictive permissions are set on local storage elements for the main SRM directory.

VOInfoPath in BDII may be the path only for SRM interface, but patgh for the related GridFTP server is different.

The SRM hostname that is advertised in BDII is not always the same site where the GridFTP server operates (but usually is). Globus Online uses GridFTP endpoints.

The tests involved the following services:

Globus Online: http://www.globusonline.eu

MyProxy server: px.grid.sara.nl

User Interface: bosui.nikhef.nl

BDII: bdii.grid.sara.nl

Storage Elements:

- DPM 1.8.2 - tbn18.nikhef.nl

- dCache 2.2.4 - srm.grid.sara.nl

- Storm 1.8.2 - bostorm.bo.infn.it

VO: dteam

SRM storage directory


-bash-3.2$ lcg-info --list-se --bdii ldap://bdii.grid.sara.nl:2170 --vo dteam --query 'SE=bostorm.bo.infn.it' --attrs 'VOInfoPath'

- SE: bostorm.bo.infn.it

 - VOInfoPath          /dteam

VOInfoPath is /dteam for SRM interface:


-bash-3.2$ srmls -2 srm://bostorm.bo.infn.it:8444/dteam

Picked up _JAVA_OPTIONS: -Xmx512M

     0 /dteam/generated

     0 /dteam/dbauer

but if we connnect using GridFTP, /dteam directory even does not exist:


-bash-3.2$ uberftp bostorm.bo.infn.it "ls /dteam"

220 bostorm.bo.infn.it GridFTP Server 6.10 (gcc64, 1334324800-83) [Globus Toolkit 5.2.0] ready.

Could not list /dteam: 500-Command failed. : System error in stat: No such file or directory

500-A system call failed: No such file or directory

500 End.

because , it is a "symlink" in SRM WS to real directory which is /storage/dteam, but only SRM interface may access it:


-bash-3.2$ uberftp bostorm.bo.infn.it "ls /storage"

220 bostorm.bo.infn.it GridFTP Server 6.10 (gcc64, 1334324800-83) [Globus Toolkit 5.2.0] ready.

Directory listing on GlobusOnline

On GO Web, if directory is empty, GO Web fails with error listing that directory, if at least on file exists it works fine.

e.g. if i try to enter the directory which is empty i get:


"Could not access /dpm/nikhef.nl/home/dteam/karolis.

Please check the path and try again.

Error listing directory '/dpm/nikhef.nl/home/dteam/karolis/' on endpoint 'ekarolis#nikhef_DPM':

Error: Embedded '/' in '/dpm/nikhef.nl/home/dteam/karolis' dirlist: dirlist/recurse.cpp:206:

void _process_direntry(MLSDEntry*, OpDirlist*): Assertion `0' failed. hide details"

It fails on Nikhef DPM node, but works fine on SARA dCache node.

SRM -> GO endpoint

Go endpoint can be created from all three types (DPM, dCache, STORM) of storage elements within EGI, but SEs have to meet some requirements:

Software versions:

GridFTP compatible versions with GlobusOnline access methods within EGI

Gathering info within EGI:

Retrieve all SEs from BDII


-bash-3.2$ ldapsearch -LLL -h bdii.grid.sara.nl -p 2170 -x -b mds-vo-name=local,o=grid '(objectClass=GlueSE)' GlueSEUniqueID|grep GlueSEUniqueID:|awk '{print $2}' > EGI_ALL_SE_HOSTS

Count how much hosts we have


bash-3.2$ wc -l EGI_ALL_SE_HOSTS

489 EGI_ALL_SE_HOSTS

OR


-bash-3.2$ lcg-info --list-se --bdii ldap://bdii.grid.sara.nl:2170 --attrs 'SE'|tr -d '\-SE:[:blank:]'|tr -s '\r' '\n'|sort|uniq|wc -l

Retrieve only SRM hosts from BDII


bash-3.2$ ldapsearch -LLL -h bdii.grid.sara.nl -p 2170 -x -b mds-vo-name=local,o=grid '(&(objectclass=GlueService)(GlueServiceType=SRM))' GlueServiceEndpoint |grep GlueServiceEndpoint| awk '{print $2}'|sort|uniq|sed -e '/managerv1/d'|sed -e 's/httpg:\/\///g'|sed -e 's/:.*//' > EGI_ALL_SRM_ENDPOINTS

Count how much SRM endpoints we have


-bash-3.2$ wc -l EGI_ALL_SRM_ENDPOINTS

423 EGI_ALL_SRM_ENDPOINTS

OR


-bash-3.2$ lcg-info --list-service --bdii ldap://bdii.grid.sara.nl:2170 --query 'ServiceType=SRM'|awk {'print $3'}|sort|uniq|sed -e '/managerv1/d'|sed -e 's/httpg:\/\///g'|sed -e 's/:.*//'|wc -l

Configuration issues:

GridFTP must accept VOMS proxy e.g. user is mapped to /home/dteam009 at storage element

Main storage directory used by SRM must allow VO member using his VOMS proxy to access it e.g. /storage/dteam, and not only his home directory which is e.g. /home/dteam009

BDII or SRM WS should provide the real path to the main storage directory used on storage element e.g. VOInfoPath from BDII MAY contain the path for SRM ONLY and SRM does the mapping to the real path, but GridFTP does not know how to do that mapping.

Note: Configuration issues may be different, depending on how EGI decides to configure SRM/GridFTP/SEs in general and how GlobusOnline finds important information within EGI):

File operations

All operations below were performed succesufully:

a) copy file using SRM and listing file using GO Web

b) copy file using GO Web and listing file using SRM

c) checking if correct Disk Used Sizes are reported by BDII (transfering at least 1GB)

d) deleting file using SRM (file was put by using GO Web)

e) deleting file using GO Web (file was put by using SRM)

f) Transfer file from NIKHEF DPM to SARA dCache.

1) Picked up few SEs:

DPM 1.8.2 - tbn18.nikhef.nl

dCache 2.2.4 - srm.grid.sara.nl

STORM 1.8.2 - bostorm.bo.infn.it

2) Finding SRM endpoints for these SEs:


-bash-3.2$ lcg-info --list-service --bdii ldap://bdii.grid.sara.nl:2170 --vo dteam --query 'ServiceType=SRM' --attrs 'ServiceEndpoint'| grep tbn18.nikhef.nl

- Service: httpg://tbn18.nikhef.nl:8446/srm/managerv2
