Migration of Euler scratch directories
Since the underlying Panasas storage system is reaching its end-of-life, we were planning to migrate all users' scratch directories (/cluster/scratch/username) to a new Lustre storage system over the coming months.
The latest power outage at CSCS and the increasing risk of catastrophic failure of the Panasas system have forced us to accelerate this plan and to move all scratch directories at once. This migration started on 13 August while Euler was still off-line and was completed on 15 August.
Except for a few hours when /cluster/scratch was accessible in read-only mode, the migration was done completely transparently. The new scratch directories are accessible under the same path as before.
Due to the change of storage system from Panasas to Lustre, the command pan_quota cannot be used any more. You can use the following command to check your scratch usage & quotas:
lfs quota `ls -d $SCRATCH`
We will provide a more user-friendly function shortly.
