Dear All
when I try to create multi snapshot volumes, sometimes the new snapshot
volume will be marked Invalid after created, somtimes remove then recreate
without problem.
is it hard disk problem?
dmesg error
attempt to access beyond end of device
dm-9: rw=17, want=2271285024, limit=8257536
device-mapper: Error reading/writing snapshot
device-mapper: snapshot is marked invalid

What kernel?
What software version?
(e.g. output of 'lvm version')
What lvcreate -s command parameters? (After how many existing snapshots?)
What configuration of original LV?
('lvs --segments -v')
Any I/O happening to any of the devices involved at around the same time?

I create snapshot while test2 is busy. (I/O origin volume)
but even I stopped writing data (already got error), sometime it still
happen. 1 out of 3
