New User 4 Drive Install

Post by Ajax » Thu Sep 20, 2012 2:01 pm

I am new to ZFS but want to build a 4 drive self healing RAID-Z pool.
I'm assuming this is as easy as installing the software and using a line similar to the following:

zpool create tank raidz /dev/dsk/c1t0d0 /dev/dsk/c2t0d0 /dev/dsk/c3t0d0 /dev/dsk/c4t0d0

Once I have done that, can I then use the volume like a normal disk? Is it compatible with iTunes etc?

Yes. I have two 4-drive RAIDZ vdevs in a pool.

The only thing to note is that the pools are case sensitive by default, which means that inconsistent names in your iTunes database could be exposed.

I had a few tracks that were variously tagged as Artistname, ArtistName and artistname (different capitalization). These would previously have gone in a single folder, but not on a Zevo drive. I only found out when doing my nightly Carbon Copy Cloner clone from a Zevo drive to a HFS drive and a bunch of errors poured out.

You'll need to use the Mac device naming. You can use "zpool showdisks" to get the names of your candidate disks. You can also use "diskutil list" to see all the disk names. We strongly recommend passing a whole disk, like /dev/diskN" to zpool create. See the QuickStart guide for some examples or look at: Wiki --> Knowledge Base --> RAIDZ Example
