We started seeing disaggregated storage test failures on the mongodb-9.0 Evergreen project, for example:

wiredtiger_mongo_v9.0_ubuntu2004_unit_test_hook_disagg_leader_extra_long

9.0 is an ASC release, so disaggregated storage is not a supported configuration there. Running these tasks only produces needless BFGs, Baron workload, and ticket creation. We previously took the same approach on 8.3.

Proposal

Disable the disagg test tasks/variants on the mongodb-9.0 branch, matching what was done for 8.3.

Discussed in this Slack thread (Luke Chen, Salman Javed).
