Transition Fraida's group to iRODS stable server (geni-gimi:1247)

[johren@bbn.com]

Fraida's students are currently using the iRODS server on emmy9:1247 which is not being monitored. We would like to transition her students to the instance on geni-gimi:1247 so we can shut down the instance on emmy9.

This task depends upon the fix to ticket #57 (iput -f fails): ​http://groups.geni.net/gimi/ticket/57

Fraida's email: I would like to make sure that the end-user experience is not affected by the switch. So there are a couple of issues holding me back from immediately switching everyone using WiMAX+iRODS to geni-gimi:

The problem with "CAT_NO_ACCESS_PERMISSION" that occurs on 'irm' or 'iput -f'. Since WiMAX+iRODS does not involve LabWiki?, the workarounds for this issue in LabWiki? aren't really suitable for us - they would not be transparent to the end user and they would degrade the user experience. Any chance of this issue being resolved? There is a class of students currently using WiMAX+iRODS quite heavily for a lab course. I would prefer for emmy9 to be maintained past the end of their class (a couple more weeks) to avoid confusion to them. (Although if it's unavoidable, I'm sure they can manage). When I make the switch, I would like to replicate my users' data to geni-gimi so nobody loses data. I don't know if this is something you are planning to do when you shut down emmy9, or if I'd have to do this myself - can you advise?

Antoine will sync up with Fraida on what needs to be done here.

Data has been transferred to new resource (renci1) (formerly irodsUMASS2) on geni-gimi. Waiting for Fraida to test this. After some time we will "trim" data on irodsUMass2 from emmy9. Eventually disable emmy9 irods server.

Waiting to hear if the transition was successful and data can be trimmed on irodsUMass2.

I haven't heard any complaints. I'm not sure if there's anything specific I should be checking - I'm not familiar enough with the details of iRODS to know what might go wrong in unexpected ways.

From Antoine: Please make sure clients are set to the "renci1" resource and data can be retrieved successfully. We will plan to shut down the emmy9:1247 iRODS server after GEC20 but leave the data intact for a period of time.

Replying to johren@…:

Please make sure clients are set to the "renci1" resource

Some users (those added on geni-gimi after #57 was fixed, but before the data was transferred from emmy9) are set to demoResc on geni-gimi. Is that a problem?

If no default resource is set for new users, what will happen? Will the server determine the appropriate resource to use?

We will plan to shut down the emmy9:1247 iRODS server after GEC20 but leave the data intact for a period of time.

That sounds good to me. Thank you.
