Error message

remove mark %v for %v

What it means

Wraps block.RemoveMark in the mark-block command with --remove: the deletion/no-compact/no-downsample mark file for the given block could not be removed from object storage (network error, missing permissions). Both the block ID and the mark filename being removed are included.

Solutions

1. Check bucket write/delete permissions
2. Inspect the wrapped error for the storage cause
3. Retry after connectivity issues resolve
