java - AWS EBS snapshot, is there a way to know if the EBS is currently being written to -

-

i making snap shot util can take snap shots of ebs. snapshots recommended take place while ebs not active(by aws), because if active while take snapshot, won't pick being written @ time of snapshot.

i wondering if there way determine if ebs being written to, or ideas of how determine such thing.

the concern whether or not volume being written when snapshot initiated. outside of instance, not able tell, unless attached instance stopped or not attached @ all.

from within instance, can freeze filesystem make consistent. don't need freeze entire duration of creating snapshot, initiating it.
