Hello,
I am learning ZFS, its design and layout.
I would like to understand how Intent logs are different from journal?
Journal too are logs of updates to ensure consistency of file system over
crashes. Purpose of intent log also appear to be same. I hope I am not missing
something important in these concepts.
Also I read that "Updates in ZFS are intrinsically atomic", I cant understand
how they are "intrinsically atomic"

I would be grateful if someone can address my query
Thanks
