Decommissioning GPFS filesystems (mira-fs0 and mira-fs1)

Help Desk

Theta and ThetaGPU

The mira-fs0 and mira-fs1 GPFS filesystems will be decommissioned on May 3, 2021 and will become read-only starting March 8, 2021.  With that in mind, we need all users with data residing on these filesystems to begin moving data that they wish to keep to alternate locations.

Options for alternate locations include:

  • archiving data to HPSS
  • transferring data to home institutions
  • transferring data to the Grand or Eagle filesystems if an active allocation exists for your project 

If you transfer your data, this should be done using Globus. Use the following endpoints: alcf#dtn_mira and alcf#dtn_theta (use the paths /eagle/<project name> and /grand/<project name>).

If the project PI wishes to share project data with the research community, they can request a storage allocation on the Eagle filesystem using the allocation request form.

We encourage everyone who wants to move their data to begin as soon as possible.

Globus Information

After preventative maintenance on May 3, mira-fs0/fs1 will no longer be accessible via Globus. The alcf#dtn_mira endpoint will be available until May 17, but /projects will now point to /lus/theta-fs0/projects.

alcf#dtn_theta will be expanded to include most of the former Mira data transfer nodes (DTNs). Note that after this change, alcf#dtn_theta will use the full pool of DTNs, so there will be no performance-related reasons to choose alcf#dtn_mira anymore and we strongly urge users to start using alcf#dtn_theta instead (to transfer data to/from theta-fs0). Any workflows referencing alcf#dtn_mira Globus endpoint should be updated to alcf#dtn_theta.

The alcf#dtn_mira Globus endpoint will be removed on May 17.

Deadlines

March 8, 2021: mira-fs0 and mira-fs1 will be mounted read-only to prohibit additional changes to the filesystems.

May 3, 2021: mira-fs0 and mira-fs1 will no longer be mounted on user facing nodes and will be unavailable to users. This includes Cooley login nodes and the Data Transfer Nodes (DTNs) used by Globus.

May 17, 2021: alcf#dtn_mira Globus endpoint will be removed.
