Maximum number of datasets?

[JBK]

Sorry, but I cannot find specific info. Is there a maximum number of datasets that can be created in a pool? Or per system? (Assuming you have the resources of course).

Thank you.

Very nice, thank you!

I kind of thought that might be the answer knowing ZFS and TrueNAS.

Please do not redirect users offsite especially for simple answers. If you want to post a link offsite to something highly complex and detailed, that's fine.

It's effectively "nearly unlimited" but may start getting impractical once you get into the thousands. This is the same way that the number of supported snapshots, while theoretically unlimited, becomes unwieldy after a certain point. The classic Solaris answer of ""On systems with 1,000s of ZFS file systems, provision 1 GB of extra memory for every 10,000 mounted file systems including snapshots."" may also be relevant.
