RAL Tier1 Operations Report for 4th February 2015
Review of Issues during the week 28th January to 4th February 2015. |
- During the afternoon of Monday (2nd Feb) there was a problem with some database services running on non-optimal nodes within the RAC. After these were moved to their correct locations some Castor service restarts were carried out to ensure the connections to the database were correct.
- A single file was reported lost to CMS. This was an old file (2012) file picked up during a consistency check.
Resolved Disk Server Issues |
- GDSS778 (LHCbDst - D1T0) did not come back after being shutdown for a reboot during scheduled work on Castor on Monday (2nd Feb). It was found to have a faulty disk drive. After being checked out it was returned to production during Tuesday afternoon (3rd) in read-only mode. It was put back in full production (read/write) this morning (4th Feb).
Current operational status and issues |
- We are running with a single router connecting the Tier1 network to the site network, rather than a resilient pair.
- There was a problem overnight with (some) CMS Condor job submissions. This is not yet understood.
Ongoing Disk Server Issues |
- None
Notable Changes made this last week. |
- Numbers of system reboots to pick up recent security patches.
- Application of Oracle patches to some database nodes.
- The backup CERN OPN link has been connected via a new route. Traffic was routed over the link for 24hours as a test.

Advanced warning for other interventions |
The following items are being discussed and are still to be formally scheduled and announced. |
- Investigate problems on the primary Tier1 router. Discussions with the vendor are ongoing.
- Physical move of 2011 disk server racks to make space for new delivery.
Listing by category:
- Databases:
- Application of Oracle PSU patches to database systems (ongoing)
- A new database (Oracle RAC) has been set-up to host the Atlas 3D database. This is updated from CERN via Oracle GoldenGate. This system is yet to be brought into use. (Currently Atlas 3D/Frontier still uses the OGMA datase system, although this was also changed to update from CERN using Oracle Golden Gate.)
- Switch LFC/3D to new Database Infrastructure.
- Update to Oracle 11.2.0.4
- Castor:
- Update SRMs to new version (includes updating to SL6).
- Fix discrepancies were found in some of the Castor database tables and columns. (The issue has no operational impact.)
- Update Castor to 2.1-14-latest.
- Networking:
- Resolve problems with primary Tier1 Router
- Move switches connecting the 2011 disk servers batches onto the Tier1 mesh network.
- Make routing changes to allow the removal of the UKLight Router.
- Enable the RIP protocol for updating routing tables on the Tier1 routers. (Install patch to Router software).
- Fabric
- Physical move of 2011 disk server racks to make space for new delivery.
- Firmware updates on remaining EMC disk arrays (Castor, FTS/LFC)
