I currently have my server setup with a Linux software RAID5 (mdamd). I have LVM on top of that, with ext3 filesystems on the Logical Volumes. This setup is mirrored on an external multi-drive enclosure.
I'm considering switching to Solaris (OpenIndiana) to use ZFS.
I understand I will have to delete the information on the server itself, but what format should I save it in on the external enclosure to transfer it back when I have finished installing OpenIndiana? I thought about formatting the drives on the enclosure in FAT32, but I wonder if there's a better method.
