FAQ

GENERAL iRODS

Is there a diagram somewhere of how this stuff is setup?
  • For NCMIR with CCDB, there is a diagram, here.
What directories store iRODS "stuff"?
  • /opt/irods
  • /etc/irods
  • /var/opt/irods
  • /var/run/irods
  • /etc/init.d
    . What files are most important in configuration and troubleshooting of iRODS?
  • /opt/irods
    • /server/bin/irodsctl (binary invoked by initscript)
    • /server/config/reConfig (iRODS rules)
  • /etc/irods
    • /<proj><env>irods (configuration files that tune the binary to a project and environment)
  • /var/opt/irods
    • /<proj><env>irods/log (log files)
  • /var/run/irods
    • /<proj><env>irods.pid (process lock file - sticks around if irods dies messily)
How can I increase the logging level?
  • (iRODS 3.2) export spLogLevel=5, then restart iRODS
  • (iRODS 3.2) spLogLevel can be set by editing irodsctl.pl or setting the environment variable spLogLevel and then restarting the server. If set to "5", it is equal to LOG_NOTICE which will log messages of the 'notice' severity and more severe (lower numbers).
What decides the default resource?

 NOTE: defaultResource does not apply to irodsAdmin users

  • (iRODS 2.5) This and other rules are in the /opt/irods/server/config/reConfig/*.irb files.
  • (iRODS 3.2) This and other rules are in the /opt/irods/server/config/reConfig/*.re files.
Are the iRODS configuration files templated?
  • Yes. See modules/m_irods/templates
Where do the values for the templates get set?
  • (iRODS 2.5) In the project module. See modules/p_ccdb/manifests/init.pp for an example.
  • (iRODS 3.2) In the m_irods module. See modules/m_irods/manifests/params.pp and modules/m_irods/manifests/ccdb/params.pp for an example.
How do I find all the files the iCAT thinks are on a particular resource?
  • iquest "SELECT RESC_VAULT_PATH, DATA_PATH, DATA_NAME WHERE DATA_RESC_NAME = 'ucsd-ccdb-prod-nas5'"
How do I move data from one resource to another?
  • In the example below:
    • permissions and ownership of the original data is changed
      • everything is owned by ccdbprodirods (aka rawdata)
      • ccdbprodirods (aka rawdata) has rw to everything
      • everything is group owned by gid=100 (aka neuro, aka users)
      • the group has read/write to anything in the montage processed_data reconstruction segmentation directories
    • any data already in iRODS is iphymv'd to the new resource, then
    • any files that have been generated, but not yet sync'd (i.e. cataloged in the iRODS database) are moved to the new resource in order to keep all the data associated with a given MPID together, then
    • any symbolic links that have been created are moved to the new resource
  • [from the directory above the relevant project on the resource that has the data you need to move...]
for i in project_20103/microscopy_46211
do for j in montage processed_data reconstruction segmentation
do  echo $i/$j
chown -R 1138 $i
chmod -R u+rw $i 
chgrp -R 100 $i
chmod -R g+rw $i/$j
iphymv -r -M -R ucsd-ccdb-prod-nas2 /telescience/home/CCDB_DATA_USER.portal/CCDB_DATA_USER/acquisition/$i

    Before running the next bit, any directories that are missing in the new location need to be created

    cd $i
find . -type f -exec mv -b --suffix=20110815 -u -v {} /ccdbprod/ccdbprod2/home/CCDB_DATA_USER.portal/CCDB_DATA_USER/acquisition/$i/{} \;
find . -type l -exec mv -b --suffix=20110815 -u -v {} /ccdbprod/ccdbprod2/home/CCDB_DATA_USER.portal/CCDB_DATA_USER/acquisition/$i/{} \;

I'm getting "rcAuthResponse failed with error -827000 CAT_INVALID_USER" in the log. What's wrong?
  • The user isn't in the iCAT. You may have misspelled the name, forgotten the extension, used the wrong zone or connected to the wrong environment.

  • In iRODS 3.2, the ACL on the top level collection is restricted to the admin user only. Use the -f flag on the 'irm' command, or modify the ACL on the trash collection.
I'm getting "ERROR: connectToRhost: error returned from host ccdb-dev-icat32.crbs.ucsd.edu status = -38000 status = -38000 SYS_AGENT_INIT_ERR ; ERROR: _rcConnect: connectToRhost error, server on ccdb-dev-icat32.crbs.ucsd.edu is probably down status = -38000 SYS_AGENT_INIT_ERR" when I run 'ils' on the iCAT and it looks like the reagent is not starting because 'ps ax' has "10620 ? Ssl 0:00 ./irodsServer PROJECT=ccdbdevirods ; 10629 ? Z 0:00 [irodsReServer] <defunct>" What's wrong?
  • The reAgent isn't starting. Check both the rodsLog and the reLog for info. It was a parsing problem with the ccdbdev.re file in this case.

  • In iRODS 3.2, the ACL on the top level collection is restricted to the admin user only. Use the -f flag on the 'irm' command, or modify the ACL on the trash collection.
Only rods user can write to dev1 and only rodsadmin can write to dev0. What's wrong?
  • I moved the dev0 vault from the slave to the iCAT using the 'iadmin modresc' command. When I moved the vault back to the slave, the problem went away.
I'm trying to do Resource Monitoring. How the heck do you get this to work?
the rule is loaded in irods cron
```iqstat -v
id     name
15249471
    msiServerMonPerf("verbose","default");
```
I modified the path in the script because it traversed up one dir too far
```#$path = dirname($0)."/../../config/scriptMonPerf.config";
$path = dirname($0)."/../config/scriptMonPerf.config";
```
when I run the script by hand it runs and generates the scriptMonPerf.config file but gives an error
``` /var/lib/irods/msiExecCmd_bin/irodsServerMonPerf -v
/var/lib/irods/msiExecCmd_bin/irodsServerMonPerf: File system path is missing!

I'm guessing that the fs is passed by the rule and is currently "default" what should I set it to? or does it come from somewhere else?

you have to store this rule in a separate file on your local 
file system or on an iRODS resource. It will be kept in the iCAT 
as it is a delayed rule being run periodically. It is a little bit like a 
cron tab.

 

What does the process list look like when I use scp to copy something to iRODS via fuse?

 It looks like the iCAT can't talk to the Oracle database. What should I do?

If you see the following in the /var/opt/irods/ccdb<env>irods/log/rodslog... file:

Try this:

sqlplus ccdbdevicat@orcl1

or this

h5. Quick Database Connectivity Test
for i in ccdbdevicat ccdbdevmcat ccdbstageicat ccdbstagemcat crbsdevicat crbsdevmcat crbsstageicat crbsstagemcat ; do echo $i ; sqlplus $i@$i ; done

If that doesn't work, check the status of the database server, including checking disk space, load, and that the database engine is running.

CCDB Portal iRODS

I want to Archive data that isn't in the data jail. What should I do?

On the poas.crbs.ucsd.edu:

  • mv the directory that contains the data to the appropriate place in the data jail and rename the directory to include the prefix "CCDBID_<MPID>_"

    • e.g.

        mv /export/crbs/ncmirdata5/eric/3view/Christine/ONH_506-L /export/crbs/ncmirdata5/rawdata/data/3view/CCDBID_45397_ONH_506-L
  mv /export/crbs/ncmirdata5/eric/3view/Christine/507-L /export/crbs/ncmirdata5/rawdata/data/3view/CCDBID_45385_507-L
  mv /export/crbs/ncmirdata5/eric/3view/Christine/507-R /export/crbs/ncmirdata5/rawdata/data/3view/CCDBID_45373_507-R
  mv /export/crbs/ncmirdata5/eric/3view/Branfman/Mouse81_cortex /export/crbs/ncmirdata5/rawdata/data/3view/CCDBID_43091_Mouse81_cortex
  • recursively change the ownership of the data

    • e.g. chown -R rawdata:users CCDBID_<MPID>_<DATA_DESC>

        chown -R rawdata:users CCDBID_45397_ONH_506-L CCDBID_45373_507-R CCDBID_43091_Mouse81_cortex CCDBID_45385_507-L
The Archive process initiated from the CCDB Portal was interrupted. What should I do?
  • FASTER OPTION - Use if no data made it to the final archive destination

    • Clear out the temporary storage space in the archive

      * irm -U -r the /telescience/home/CCDB_DATA_USER.portal/<scope>/<MPID_directory>

    • Remove any <MPID_directory> data from the archive

      Only do this if you're SURE it's safe to delete everything under the <MPID_directory> (It should be either empty, or have only data for which a copy still exists in the data jail. The next command assumes all rawdata in the archive for that MPID can be DELETED. All rawdata for that <MPID_directory> must be in the data jail before using this procedure.

      rm -rf the /ccdbprod/ccdbprod1/home/CCDB_DATA_USER.portal/CCDB_DATA_USER/acquisition/project_####/<MPID_directory>
    • "Archive" the data again from the CCDB Portal

ALTERNATIVE

  • SAFER OPTION - Use if some, but not all data made it to the final archive destination

    • md5sum each file in the data jail and compare to md5sum for corresponding file in final archive destination

      cd /ccdbprod/ccdbproddj0/<scope> ; for i in `find <MPID_directory> -type f` ; do md5sum $i ; md5sum /ccdbprod/ccdbprod1/home/CCDB_DATA_USER.portal/CCDB_DATA_USER/acquisition/project_####/$i/done
    • If the md5sums do not match, correct it so that the correct file is in both places.

    • Do an iscan on the archive directory to see if any files were registered with iRODS, but which never made it to the right place on the disk.

      If files show up as "orphaned" (meaning it's on the disk, but not cataloged in iRODs), they need to be "sync"d via the CCDB Portal.

      [ccdbprodirods@ccdb-irods rawdata]$ iscan -r /ccdbprod/ccdbprod1/home/CCDB_DATA_USER.portal/CCDB_DATA_USER/acquisition/project_20099/microscopy_45249/rawdata/CCDBID_45249

      An ils of an orphaned file will says it doesn't exist in iRODS.

      [ccdbprodirods@ccdb-irods rawdata]$ ils -L /telescience/home/CCDB_DATA_USER.portal/CCDB_DATA_USER/acquisition/project_20099/microscopy_45249/rawdata/CCDBID_45249/CCDB_MetaData/sutterlinGrid2Control_instrumentMetaData.txt

    • Copy any missing files from the data jail to the final archive location

      Be careful not to overwrite data you don't want to be overwritten - copy only the missing files, or try using 'cp -i ...'

      [ccdbprodirods@ccdb-irods rawdata]$ cp -r -i /ccdbprod/ccdbproddj0/3view/CCDBID_45249/<some_dir>/<some_file> /ccdbprod/ccdbprod1/home/CCDB_DATA_USER.portal/CCDB_DATA_USER/acquisition/project_20099/microscopy_45249/rawdata/CCDBID_45249/<some_dir>/<some_file>

    • "sync" the archive directory via the CCDB Portal.
      The portal will send email telling you the data has been synced.

How do I know if the service started properly?

  • ON AN ICAT you'll see both an irodsServer ANDand irodsReServer process running. The output of `ps ax | grep irod` should look like this:
