TSD Operational Log - Page 4

On the 11th of April at 15:00, TSD will migrate the shared directory to the new storage system. The shared directory is a read-only export available to all TSD projects ("/tsd/shared" on Linux or "\\tsd-evs\shared" on Windows).

Please note that the migration will not impact regular shared project directories such as pXsharedpY and its variants.

We need to conduct a routine upgrade of TSD's storage system between 10:00 and 11:00 on Wednesday, April 19, 2023.

During the downtime, it will still be possible to log in to VMs, but durable storage (M:\ and N:\ in Windows VM) will be unavailable. Therefore, we recommend closing all open files and potentially logging out to avoid data loss. Colossus is unaffected and will operate normally throughout the upgrade.

ESS storage is currently unavailble due to a technical problem. There was a firmware-bug in our IBM setup, the bug caused a metadata-server to crash, and a global disk failure. As there was a minor risk of data-loss or data-corruption we had to spend about 9 hours yesterday working together with the international crisis team in IBM. System was up at about 1900 yesterday (23/3-23) and we believe there was no data-loss or corruption. 
We sincerely apologize for this unplanned downtime, but third party bugs in firmware setups is a very unforeseen happening that we could not have easily prevented.
During the downtime we also fixed the MTU settings that IBM had misconfigured and may have been the root cause of previous truble. We also attached more storage, which will soon be put into production. 

Due to a previous misconfiguration from IBM, we will reconfigure our storage on Thursday March 23 from 12:00. This may cause network storage downtime on Windows and Linux clients. The Colossus compute nodes might be affected, but we consider that very unlikely.

We're experiencing NFS hangs due to third party maintenance on our storage system.

We'll be rebooting hosts to resolve the issue.

We're experiencing NFS hangs. 

We're working to fix it and will have to reboot hosts in the process.

Affected services:

- login to Nettskjema with TSD

- login to TSD virtual machines

- selfservice portal

- data portal (and command-line imports)

- publication portal

- consent portal

We are working to fix this.

ESS NFS clients experience NFS hangs. Some clients may be rebooted to resolve the issue. 

We're actively working on resolving the issue.

Starting Wednesday 2022-02-08 15:00 the NFS servers in TSD will be upgraded by a third party vendor.

We expect this to take approximately 1 hour and may cause network/NFS interruptions.

We advice you to keep an eye on this operational log for any updates.

ESS NFS clients experienced NFS hangs on 2023-01-30 between 16:00 and 18:00. Clients were forced to remount NFS. 

For some non-ess-migrated projects NFS hangs persisted until 2023-01-31 09:30. 

We apologize for the inconvenience.

Update 2023-01-31 1200: Several hosts are still experiencing hangs. These hosts will be rebooted asap.

The new dataloader is currently unavailable.

This only affects nettskjema which have been enabled for the new version, for projects p2336 and up.

We're currently working on a fix.
