The new compatibility job failed with ENOENT and I can reproduce it on the directory. However the LSM chunk file exists on disk and the table exists in the metadata:
% sudo ../build_posix.develop/wt -h test/format/RUNDIR verify table:wt wt: session.verify: table:wt: No such file or directory % sudo ./wt -h test/format/RUNDIR verify table:wt % sudo ./wt -h test/format/RUNDIR list -v metadata: ... colgroup:wt app_metadata=,collator=,columns=,source="lsm:wt",type=lsm file:WiredTigerLAS.wt ... file:wt-000012.lsm ... table:wt app_metadata=,colgroups=,collator=,columns=,key_format=u,value_format=u
So this appears to be real and should be understood.
The failing job is at:
