Problems with Reference Disk Mount

[jbakerpmc]

Hello cromwell dev team,

I'm currently working with the reference-disks option using GCPBatch as my backend. I executed the create_images.sh script from the documentation (https://cromwell.readthedocs.io/en/develop/backends/GCPBatch/) to generate my reference-disk-localization-manifests. I'm also using Cromwell v87, as specified in the same documentation. I also tested with the current develop build

While the manifest is correctly configured in the Cromwell config, and the reference disk appears to be mounting successfully, I’m encountering a failure with the umount command. I’m not sure why this command is being invoked in the first place.

Mount Image

Error Message:

severity: "DEFAULT"
textPayload: "umount: /mnt/2d49bcb009113835140d638a10b535af: no mount point specified."
timestamp: "2024-09-26T14:07:54.88114

Below is an example of what I have included in my Cromwell configuration (cromwell.conf).

reference-disk-localization-manifests = [
  {
    "imageIdentifier" : "projects/private-test-cromwell/global/images/omics-reference-disk-image",
    "diskSizeGb" : 10,
    "files" : [ 
      {
        "path" : "test-cromwell-references/hg38/v0/Homo_sapiens_assembly38.dict",
        "crc32c" : 2158779318
      },
      {
        "path" : "test-cromwell-references/hg38/v0/Homo_sapiens_assembly38.fasta",
        "crc32c" : 420322484
      },
      {
        "path" : "test-cromwell-references/hg38/v0/Homo_sapiens_assembly38.fasta.fai",
        "crc32c" : 1970999569
      }
    ]
  }
]

@mcovarr and @aednichols, I have seen issue #7502
