Data instability was seen today in the Indianapolis-based BDII (is2.grid.iu.edu) between the hours of 18:30 UTC and 21:45 UTC. During this time availability of OSG Sites Data was inconsistent.
The problem was traced back to a IP renumbering project which had unforeseen affects on our internal DNS and LDAP. As soon as the issue was identified, the maintenance was stopped and service was rolled back to the pre-maintenance configuration.

GOC Service Upgrade - Tuesday, October 26th at 14:00 UTC
The GOC will upgrade the following services beginning at Tuesday, October 26th, 2010 at 14:00 UTC. The GOC reserves four hours (14:00 - 18:00 UTC) in the unlikely event that unexpected problems are encountered.
Tuesday, October 26th at 14:00 UTC
OIM 2.26 (https://oim.grid.iu.edu)
ITB version is now available for testing at https://oim-itb.grid.iu.edu; we encourage users to test this service before the production release.
Added features to store and allow editing of TWiki IDs.
Minor layout change on resource editor (indented wlcg_accounting_name field)
MyOSG 1.28 (https://myosg.grid.iu.edu)
ITB version is now available for testing at https://myosg-itb.grid.iu.edu; we encourage users to test this service before the production release.
[Misc / ServiceStatus] Reduced the number of services with UNKNOWN status
Minor CSS change for Status Map (for better integration with OSG Display)
GOC Ticket 1.29 (https://ticket.grid.iu.edu)
ITB version is now available for testing at https://ticket-itb.grid.iu.edu; we encourage users to test this service before the production release.
Added submitter information when a ticket is initially created (similar to previous fix made on missing submitter when non-Footprint agent updates a ticket)
Moved the form explanations verbiage to each submission page
Minor CSS change for Filter box on ticket navigator (shorten it slightly)
Redhat Enterprise Linux Software Updates
We will be installing software updates that do not require system restarts, so no downtime is expected due to this. Since last month, the only software update Redhat has released that affects GOC systems and is marked Critical is a security update to the java-1.6.0-sun package. There are also a number of updates of lesser importance, which we will also install, with a few exceptions. Some of those noncritical updates are to the kernel, glibc, and related packages, which would require system restarts, so we will not be installing those at this time. The only packages we will update will be those that do not require system restarts.

Reminder: GOC Machine Room Maintenance - Tuesday, October 12th at 14:00 UTC
Due to a site-wide machine room reorganization the GOC will be moving its Indianapolis-based servers to a new rack beginning at 14:00 UTC on Tuesday, October 12, 2010.
The moving of each server will take only a short time, probably no more than 10 minutes, but we are reserving up to an hour in case of unexpected complications. We will be using the DNS round-robin to shift traffic to the Bloomington servers during this time where possible (CEMon/BDII, MyOSG, the OSG Software Cache, and the GOC Ticketing System).
Services that will be affected include:
BDII: Will remain online but may experience degraded service. We have seen ATLAS SAM test failures while doing similar maintenance.
OSG TWiki: Will experience a short downtime during this window.
OSG Information Management (OIM): Will experience a short downtime during this window.
The move to the new rack should result in improved cooling and power infrastructure for the GOC's Indianapolis-based servers. We appreciate everyone's patience during this transition.

CEMon/BDII - *ITB Only* (http://is-itb.grid.iu.edu)
* Install-Capacitor filtering script / Storage capacity adjustments
o processing of storage capacity based on resource group and resource name
o adjustment of storage capacity based on OIM data
* Added new monitors & munin metrics.
* Increased the number of processors assigned to 2
Software Cache (https://software.grid.iu.edu)
* For the Certificate form, vo-sponsor file was updated.
OSG Display 1.0.7 (http://display.grid.iu.edu)
* Changed the data load frequency indicator to 10 minutes. 5 minutes update was causing too much load on source Gratia DB. It is now update every 10 minutes.
GOC Ticket 1.28 (https://ticket.grid.iu.edu)
Bug Fixes
* Fixed the bug where non-admin edit doesn't mark the generic submitter's name in the description and metadata [GOCTICKET-75]
* Fixed the mailto encoding issue for the ticket viewer
All Servers - Renumber Private VLAN IPs
This will not affect the public IPs of any servers; it will only affect the internal private VLAN that the GOC uses to allow servers to talk privately amongst themselves. There may be slight service irregularities, but nothing that is expected to last more than a few minutes as the various nameservice caches expire.

OSG 1.2.14 Release Notification
OSG Operations and Integration are pleased to announce the release of OSG version 1.2.14.
The following components are affected:
* CE installations
* CEMon being used for reporting on larger sites
* OSG client and wn-client installation (due to updates to MyProxy, Fetch-CRL, Glexec, and OpenLDAP)
* Sites using Glexec
This release also incorporates smaller fixes to a variety of components distributed in the OSG stack. Although any given change is not very large, a large number of components have been updated.
Highlights of the changes include:
* setup.sh is no longer sourced by the Globus jobmanager, reducing the load and I/O on gatekeepers
* Tomcat's settings have been altered to use 512MB of memory, this helps to avoid out-of-memory error in CEMon seen by larger sites
* the vdt-updater script has been altered so that subsequent updates will not require a second backup
* Glexec has been updated and includes a fix for users that have run a grid-proxy-init instead of voms-proxy-init
* small security updates to MySQL, Apache httpd, and OpenLDAP
* LFC has been updated to 1.7.4-7
See the VDT release notice for more detailed information. Notable fixes include support for grid-proxy-init in Glexec and security fixes in MySQL, Apache, and OpenLDAP.
Update instructions can be found on the OSG Twiki under the OSG 1.2 update instructions:
https://twiki.grid.iu.edu/bin/view/ReleaseDocumentation/OSG12UpdateInstructions
