Heads up:
We’re moving the GATK website, docs and forum to a new platform. Read the full story and breakdown of key changes on this blog.
Update: July 26, 2019
This section of the forum is now closed; we are working on a new support model for WDL that we will share here shortly. For Cromwell-specific issues, see the Cromwell docs and post questions on Github.

localization errors

I've set cromwell (30.2) to only use hard-link and soft-link to localize files (so I removed "copy" from the available options). However, I keep getting these errors:

Could not localize /data/reads/illumina/nvwa/103200-007/rawdata/103200-007-035_2.fastq.gz -> /data/Experiment/redmar/Experiment_105/cromwell-executions/trim/cd1ba924-bd0d-4f75-af05-924555364a73/call-before/shard-34/inputs/data/reads/illumina/nvwa/103200-007/rawdata/103200-007-035_2.fastq.gz: 
        /data/reads/illumina/nvwa/103200-007/rawdata/103200-007-035_2.fastq.gz doesn't exists
        /data/Experiment/redmar/Experiment_105/cromwell-executions/trim/cd1ba924-bd0d-4f75-af05-924555364a73/call-before/shard-34/inputs/data/reads/illumina/nvwa/103200-007/rawdata/103200-007-035_2.fastq.gz -> /data/reads/illumina/nvwa/103200-007/rawdata/103200-007-035_2.fastq.gz: Operation not permitted

I've tried manually linking the required files into the cromwell folder using ln -s, which works.
I'm not the owner of the /data/reads/illumina/nvwa/103200-007/rawdata/103200-007-035_2.fastq.gz file, and I'm using docker, so I'm not sure if that has something to do with this issue.

The weird thing is that the workflow doesn't terminate due to this errors, it just goes to the next shard or the next task, and keeps creating execution folders, without placing anything in them. It also creates the inputs folder and the hierarchy inside it, but then it doesn't actually localize any of the files.
