Convert ZFS to USF with data/jails.

[bryn1u]

Hey,

I need to do back to the UFS filesystem because I need a few things from MAC TrustedBSD which don't work under ZFS. I have two jails on ZFS jails/jail1 and jails/jail2. Is there any hope and way to convert to UFS?

Thanks,

None. You can't convert from ZFS to UFS or vise verse. You will have to backup the data and restore it.

Perhaps your best option could be creating a ZVol with zfs create -V <size> <dataset name> and creating a UFS volume on that, essentially using ZFS as an LVM.
