Ooops. You likely did not want that. That reverts the origin volume
to the snapshot by copying the original data for updated sectors from
the snapshot. This is an extremely useful feature, but *not* when
you invoke it accidentally!
I'm wondering if I really want this 'merge' it wants to do...and if not,
how do I abort it?
If it is really delayed until boot (or close), then you have a chance to
abort
it, but I don't know how. I hope an expert answers. Meanwhile, I'll
peruse the man page to see if it talks about delayed merge.
The man page says:
If both the origin and snapshot volume are not open the merge will start
immediately. Otherwise, the merge will start the first time either the
origin or snap??? shot are activated and both are closed. Merging a snapshot
into an origin that cannot be closed, for example a root filesystem, is
deferred until the next time the origin volume is activated. When merging
starts, the resulting logical volume will have the origin's name, minor
number and UUID. While the merge is in progress, reads or writes to
the origin appear as they were directed to the snapshot being merged. When
the merge finishes, the merged snapshot is removed. Multiple snapshots may
be specified on the commandline or a @tag may be used to specify multi??? ple
snapshots be merged to their respective origin.
If you have space, I would copy your origin LV while you can. There is
nothing about cancelling the merge. I suspect you could restore the metadata
backup from before your merge. But make backups first!
