I soon discovered that instead of mounting the filesystem, an lvm snapshot of the filesystem was mounted instead
This occurred because I had an fstab line of the form
UUID=821f.... /store/whateverand both the original filesystem and the snapshot have the same UUID!
This is perhaps obvious when you think about what an lvm snapshot is, but it sure led to an unexpected result!
Lesson: when using lvm, specify mounts using the /dev/pvname/lvname notation
unless you're sure you'll never use snapshots.
