Current ZFS implementation (Solaris 10 11/06) has some issues admins should know before deploying it. These issues are not inherent to ZFS, and might be solved in future releases:
* While there is both ZFS root and ZFS boot support are readily available, ZFS root filesystem support is currently set off on Solaris 10 default installations, since the standard installer still does not fully support ZFS roots. To create bootable ZFS systems one needs to use scripts or do it manually. The ZFS Boot project recently successfully added boot support to the OpenSolaris project, and is available in recent builds of Solaris Nevada.<ref>{{cite web | title = Latest ZFS add-ons | date = 2007-03-28 | work = milek's blog | accessdate = 2007-03-29 | url = http://milek.blogspot.com/2007/03/latest-zfs-add-ons.html }}</ref><ref>{{cite web | title = ZFS Bootable datasets - happily rumbling | date = 2007-03-29 | work = Tim Foster's blog | accessdate = 2007-04-01 | url = http://blogs.sun.com/timf/entry/zfs_bootable_datasets_happily_rumbling}}</ref> ZFS boot is currently (20070208) planned for a Solaris 10 update in late 2007.
* If a Solaris Zone is put on ZFS, the system cannot be upgraded — the OS will need to be reinstalled. This issue is planned to be addressed in a Solaris 10 update in 2007 {{Fact|date=August 2007}}.
