datadir

Overview ¶

Package datadir names the on-disk data root, once.

It is a leaf so that the light router in cmd/cloud can agree with the request tier about WHERE the volume is without linking it. That agreement is load bearing: the router takes the pod's writer lease on a lock file under this path and the children open their stores under it, so a second definition that drifted by one directory would put the lock somewhere nothing else consults — an interlock guarding an empty folder.
