20220506 / Migration News, scratches

Debian11/Slurm Upgrade was not planned to be a one-day operation:

then Summer holydays…

In the meantime:

Please do test and prepare your slurm scripts…

Be aware that homes and groups/teams storages (/Xnfs) are the same between systems.

Then, in September, we'll see (E5 and Lake clusters final migrations, scratches migrations).

You are doing it wrong (mostly).

DO NOT store scripts, SGE/slurm logs, small files, source code, binaries on Scratches: it degrade general performance VERY fast, for everyone.

Scratches are meant for large temporary files, and large I/O operations, WITHIN a job. That's all.

DO cleanup!!! Everytime a job is finished, scratch should be clean up (with exception for long workflows)

DO VERIFY your cleanup operations!!

General purpose scratches (E5N/, Lake/) are full again. We will erase files older than 90 days next week (blind shoot).
