Couldn't canonicalise: Failure

Post by njd » Fri May 03, 2019 3:44 am

We are sending files from z/OS to a Linux server with windows mounted disks and occasionally we get a " Couldn't canonicalise: Failure " that shows with -vvv debug coded. A straight rerun on the job works. Anyone know how we can find what is causing the problem?

I would need to see a fragment of the log file to be sure, but it sounds like you are try to open a file on the server that doesn't exist.

" Couldn't canonicalise: Failure "
is the somewhat cryptic error from OpenSSH that means that a component directory in the file path was not found.

This is an error that is return from the remote server, so you would want to look there for the reason. Likely there is an intermittent problem with the filesystem mounts.
