[linux-lvm] LV snapshot and filesystem sync

[Piergiorgio Sartor]

Hi all,

I apologize in advance in case this was already
discussed, but I seem not to be able to find a
clear answer, using the standard search engines.

The question is: when doing a snapshot of a LV
volume, is it necessary to "sync" the filesystem
above? Or is it done automatically?

If done automatically, does it work with all
filesystems or only with some? Which?

Thanks a lot in advance,

bye,
