In test format, we may run a workload in a follower only mode. But because the leader didn't involves in this test so nothing should be persisted and we should skip the verify.

Context

Test: format-stress-test-disagg-follower

Key repro steps:

• Run disagg with following config (full file CONFIG):

  • disagg.mode=follower
    runs.mirror=1
    # forces table1 to be the plain, non-disagg mirror base
    table1.disagg.enabled=0
    # required alongside it — enabled=0 alone still trips a different config-consistency assert
    table1.runs.source=table  
    # isolates the mechanism from an unrelated confound
    ops.pct.delete=0             
    # 100/1,000 rows self-heal in time; 3,000 fails by 2 keys
    runs.rows=3000                
    runs.timer=1 

• Run test format + restart (full script run.sh):
  • ./t -c for first round
  • ./t -R -h for second round you'll see the error

Expected error:

mirror: 3289/3290 mismatch: table:T00001: {0000003289.00/opqrstuvwxyza}/{000000328-----------------gfed--bazyxwvut}, table:T00002: {0000003290.00/opqrstuvwxy}/{0000003290/LMNOPQRSTUVWXYZA}
last successful match was 3288
