Maintenance on storage system Lupus 2016-11-15 -- now CLOSED

2016-11-14

Tomorow November 15th about 9:00 hours we are going to start maintenance window for our storage system Lupus. The following actions will be taken:

  • BIOS upgrade on storage servers
  • Firmware upgrade on storage arrays

When those actions are completed we are going to start filesystem check on the parts of the filesystem. We hope that we should be finished before the weekend, depending on how long time the filesystem check can take.

Update at 17:00 hours

We need to perform additional steps in order to proceed with firmware and BIOS upgrade. The upgrade and reconfiguration of management software running on storage system is also required and recommended by our support provider. We are going to continue the work tomorrow.

Upgrade and reconfiguration of storage management software on Lupus is now completed and we can proceed with firmware and BIOS installations.

We are still busy upgrading the firmware on all the storage arrays on Lupus. We hope this process will be finished soon. Then we are going to continue with BIOS upgrade and filesystem check.

Update 2016-11-18 at 12:00 hours

We have finished firmware upgrade on all the storage arrays on Lupus. The upgrading process went good and the arrays are doing fine.
Now we can start with BIOS upgrades on the storage servers. We are hoping to be able to start fsck on Lupus before the weekend.

Update 2016-11-21 at 12:00 hours

We have finished all the upgrades on all physical machines which Lupus consist of. We have also done filesystem check and fixed all errors found on it. However there are still some error messages appearing in the log files and we are still working on in it together with our support provider.

There are still some errors in the logs on Lupus, and we are still investigating this issue together with our support provider.
But we also got ensured that Lupus is stable enough to be taken into production use.
We are going to update System News when all those minor problems was resolved but for now we are closing the maintenance window on Lupus.
