Jump to: navigation, search


Tests have been carried out while creating this Cookbook.

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:

The tests involved the following services:


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:


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

483


Probe for GridFTP 2811 port EGI_ALL_SE_HOSTS


-bash-3.2$ for i in `cat EGI_ALL_SE_HOSTS`;do echo ¨Connecting to $i `nc -w 2 $i 2811`¨;done|tee EGI_ALL_SE_GRIDFTP_VERSIONS

Count how many of them responded with GridFTP open


-bash-3.2$ grep FTP EGI_ALL_SE_GRIDFTP_VERSIONS|wc -l

299

What are the GridFTP Server versions


-bash-3.2$ awk '{print $8}' EGI_ALL_SE_GRIDFTP_VERSIONS|sort|uniq

2.3

2.7

2.8

3.23

3.28

3.33

6.10

6.14

6.5

Lets see how many types of storage exists in EGI


-bash-3.2$ ldapsearch -LLL -h bdii.grid.sara.nl -p 2170 -x -b mds-vo-name=local,o=grid '(&(objectClass=GlueSE))' GlueSEImplementationName|grep ^GlueSE|sort|uniq

GlueSEImplementationName: ARC

GlueSEImplementationName: classicSE

GlueSEImplementationName: dcache

GlueSEImplementationName: dCache

GlueSEImplementationName: DPM

GlueSEImplementationName: HDFS

GlueSEImplementationName: StoRM

GlueSEImplementationName: xrootd

How many of DPM, dCache, Storm ?


-bash-3.2$ ldapsearch -LLL -h bdii.grid.sara.nl -p 2170 -x -b mds-vo-name=local,o=grid '(&(objectClass=GlueSE)(GlueSEImplementationName=dcache))' GlueSEUniqueID|grep ^GlueSE|wc -l

79

-bash-3.2$ ldapsearch -LLL -h bdii.grid.sara.nl -p 2170 -x -b mds-vo-name=local,o=grid '(&(objectClass=GlueSE)(GlueSEImplementationName=dpm))' GlueSEUniqueID|grep ^GlueSE|wc -l

217

-bash-3.2$ ldapsearch -LLL -h bdii.grid.sara.nl -p 2170 -x -b mds-vo-name=local,o=grid '(&(objectClass=GlueSE)(GlueSEImplementationName=storm))' GlueSEUniqueID|grep ^GlueSE|wc -l

54


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

420


Configuration issues:

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

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

-bash-3.2$ lcg-info --list-service --bdii ldap://bdii.grid.sara.nl:2170 --vo dteam --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

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

- Service: httpg://bostorm.bo.infn.it:8444/srm/managerv2

 - ServiceEndpoint     httpg://bostorm.bo.infn.it:8444/srm/managerv2

3) Finding SRM VO home path for these SRM endpoints:


-bash-3.2$ lcg-info --list-se --bdii ldap://bdii.grid.sara.nl:2170 --vo dteam --query 'SE=tbn18.nikhef.nl' --attrs 'VOInfoPath'

- SE: tbn18.nikhef.nl

 - VOInfoPath          /dpm/nikhef.nl/home/dteam

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

- SE: srm.grid.sara.nl

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

-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

4) Listing files in SRM endpoints:


-bash-3.2$ srmls -2 srm://tbn18.nikhef.nl:8446/dpm/nikhef.nl/home/dteam

Picked up _JAVA_OPTIONS: -Xmx512M

 0 /dpm/nikhef.nl/home/dteam/

< output truncated >

-bash-3.2$ srmls -2 srm://srm.grid.sara.nl:8443/pnfs/grid.sara.nl/data/dteam

Picked up _JAVA_OPTIONS: -Xmx512M

 512 /pnfs/grid.sara.nl/data/dteam/

< output truncated >

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

Picked up _JAVA_OPTIONS: -Xmx512M

 0 /dteam/

< output truncated >

5) Listing used and total space on SEs (in GB units):


-bash-3.2$ ldapsearch -LLL -h tbn18.nikhef.nl -p 2170 -x -b mds-vo-name=resource,o=grid '(&(objectClass=GlueSA)(GlueSAAccessControlBaseRule=VO:dteam))' GlueSATotalOnlineSize GlueSAUsedOnlineSize

dn: GlueSALocalID=test:replica:online,GlueSEUniqueID=tbn18.nikhef.nl,Mds-Vo-na

me=resource,o=grid

GlueSATotalOnlineSize: 32

GlueSAUsedOnlineSize: 4

-bash-3.2$ lcg-info --list-se --bdii ldap://bdii.grid.sara.nl:2170 --vo dteam --query 'SAVOs=VO:dteam' --attrs 'UsedOnline,TotalOnline'|grep srm.grid.sara.nl -A 7

- SE: srm.grid.sara.nl

 - UsedOnline          0

                       0                             

                       0                             

 - TotalOnline         0

                       15000                         

                       58681

Note: three values because it is dCache.

-bash-3.2$ lcg-info --list-se --bdii ldap://bdii.grid.sara.nl:2170 --vo dteam --query 'SAVOs=VO:dteam' --attrs 'UsedOnline,TotalOnline'|grep bostorm.bo.infn.it -A 3

- SE: bostorm.bo.infn.it

 - UsedOnline          0

 - TotalOnline         100

6) Uploading file from UI via SRM client to SE endpoint:


-bash-3.2$ srmcp -2 file:///100M.rand  srm://tbn18.nikhef.nl:8446/dpm/nikhef.nl/home/dteam/100M.rand -debug

Picked up _JAVA_OPTIONS: -Xmx512M

Note: In the log above we see that in fact the real SE endpoint is "hooiwagen.nikhef.nl", which is not advertized in BDII, but pre-configured inside SRM WS.

But we can use lcg-gt as well:


-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 gsiftp
-bash-3.2$ gsiftp://bee33.grid.sara.nl:2811/pnfs/grid.sara.nl/data/lsgrid/test


7) Listing file via GO Web and deleting the file via GO Web.


-bash-3.2$ srmls -2 srm://tbn18.nikhef.nl:8446/dpm/nikhef.nl/home/dteam/100M.rand

Listing file with SRM client:


-bash-3.2$ srmls -2 srm://tbn18.nikhef.nl:8446/dpm/nikhef.nl/home/dteam/karolisPicked up _JAVA_OPTIONS: -Xmx512M

 0 /dpm/nikhef.nl/home/dteam/karolis/

     5242880000 /dpm/nikhef.nl/home/dteam/karolis/5G.rand

After upload:


-bash-3.2$ ldapsearch -LLL -h tbn18.nikhef.nl -p 2170 -x -b mds-vo-name=resource,o=grid '(&(objectClass=GlueSA)(GlueSAAccessControlBaseRule=VO:dteam))' GlueSATotalOnlineSize GlueSAUsedOnlineSize
