I finally got some new drives for my Ultra 80. I have two 73gig 10K RPM SCSI disks in it now with 60GB in a ZFS mirror. I am going to be adding 4x500G SATA disks in a RAIDZ, and I was thinking about using the "old" zfs space on the SCSI disks for intent logs.
My questions are this: 1) Is it possible to add intent log devices after the fact? (I'll need to build the new array first so I can move the data over to it.) 2) What would be a better use of the two 60G intent log partitions? Mirrored? Striped? 3) How much space is needed for the intent logs? For 1.5TB of data space, would 60G be enough? 120G? 4) What version should I be running? I've got 64a on it now, but have be considering upgrading to the latest SCXE. I guess a lot of this revolves around the answer to #1, since if I can do thing after the fact with regards to intent logs, then I can answer those other questions at a later date.
