pub enum UnknownReason {
MoverUidUnpinned,
WorkloadUidUnpinned,
OnlyGroupOverlap,
NoConsumerPod,
NfsOrNoPvc,
FsGroupMayApply,
}Expand description
Why a backup read-compatibility verdict is undecidable from the spec alone.
Variants§
MoverUidUnpinned
The mover’s UID is image-determined (no runAsUser); nothing to compare.
WorkloadUidUnpinned
At least one workload writer’s UID is image-determined.
OnlyGroupOverlap
UIDs differ but the mover shares a group with the file group — might read via the group bit (which we can’t see), so we abstain.
NoConsumerPod
No pod currently mounts the source PVC (offline workload / mid-rollout).
NfsOrNoPvc
The source is NFS (or has no single PVC) — ownership is NAS-determined and fsGroup
is ignored; nothing to assess.
FsGroupMayApply
The source is mounted read-write and the mover declares an fsGroup, so the kubelet
may recursively chgrp the tree to it before the mover reads — which would make
the source readable regardless of who wrote it. Whether it actually does is not
knowable from the spec (the CSIDriver’s fsGroupPolicy may be None, or the default
ReadWriteOnceWithFSType, which skips RWX volumes; and fsGroupChangePolicy: OnRootMismatch skips the walk when the root group already matches), so we abstain.
