I have been researching different types of raids, and I happened across raidz, and I am blown away. I have been trying to find resources to answer some of my questions, but many of them are either over my head in terms of details, or foreign to me as I am a linux noob, and I have to admit I have never even looked at Solaris.
Are the Parity drives just that, a drive assigned to parity, or is the parity shared over several drives? I understand that you can build a raidz2 that will have 2 parity disks. So in theory I could lose 2 disks and still rebuild my array so long as they are not both the parity disks correct? I understand that you can have Spares assigned to the raid, so that if a drive fails, it will immediately grab the spare and rebuild the damaged drive. Is this correct? Now I can not find anything on how much space is taken up in the raidz1 or raidz2. If all the drives are the same size, does a raidz2 take up the space of 2 of the drives for parity, or is the space calculation different? I get that you can not expand a raidz as you would a normal raid, by simply slapping on a drive. Instead it seems that the preferred method is to create a new raidz. Now Lets say that I want to add another raidz1 to my system, can I get the OS to present this as one big drive with the space from both raid pools? How do I share these types of raid pools across the network. Or more specifically, how do I access them from Windows based systems? Is there any special trick? -- This message posted from opensolaris.org _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
