VolumeUnmountUnsupportedError

Package: flyteplugins.union.errors

The runtime cannot unmount the FUSE client at all because fusermount can’t reach its mount table (/etc/mtab is missing, read-only, or unwritable). Unlike a transient :class:VolumeUnmountError (EBUSY), retrying won’t help — the image is missing the /etc/mtab → /proc/self/mounts symlink most base images carry. The terminal seal treats this as recoverable: it falls back to a keep-alive (live) commit, leaving the mount in place. A kind of :class:VolumeUnmountError, so except VolumeUnmountError catches it too.

Parameters

class VolumeUnmountUnsupportedError(
    message: str,
)
