Is it worth the risk Upgrading the ZFS pool ?

[AlcSi]

Hi,
Just upgraded from 9.2.1.6 to 11.2, went pretty much flawless.

I now obviously have this alert about the upgrade of my ZFS pool for new feature flags.

Should I do it ?
Note that this server is a production server, and that it is intended to be running for as long as we can keep it alive...
I don't think we use the new feature flags, but maybe next updates to FreeNAS will need them ?

Sorry for the newbie-questions and thanks for any inputs

Unless you need the new features I wouldn't upgrade. I believe FreeNAS might add proprietary things into their version of ZFS which may be incompatible with other ZFS versions.

I doubt that FreeNAS adds proprietary ZFS flags, but FreeBSD might push ahead on features that other OS distros are slower to follow. This is not much of an issue for me.

I generally do not update the feature flags until I know that I will not be downgrading FreeNAS to an earlier build. I usually wait for several weeks after doing an upgrade to make this decision. That said, there is no compelling reason to update the flags unless there is a new feature that would be useful. If, at some point in the future, an update is required, then I would expect the FreeNAS update mechanism to say as much.
