If I install a new IDE disk into a freshly installed 2008.11 (101b) that resides on a partitioned disc. The new install claiming 25GB leaving 35gb more I wanted to get into a raidz pool.
What do I really need to do to create a raidz pool using this disk? I don't mean the mechanics of creating the zpool, that seems well documented. I mean like if the disk has partitions from another os? Do I need to `format/fdisk' and remove the partitions? Then create a single partition for the whole disk? If so, at the part it prompts you for a type of file system, what do I need to do there? Also, assuming the disk I installed on is also partitioned leaving 25 GB for sol-11 (1101b) and 35 to use in a zpool. What do I need to do to the remaining un-partitioned part of the disc? Again, we run into the filesystem type prompt. If I create a second partition encompassing the rest of the disk, how to tell zfs about it? In the online demos I've seen the raid1z is created using only the discs that `format' sees. Or is all the partitioning anxiety completely unnecessary? I may just be blind but, the supposed Bible of OpenSolaris appears to have pretty thin treatment in this area. It goes over ZFS a bit but I'm not finding details about preparing disks for use, or what to do with disks that have partitions. At least one demo site (Simons blog about zfs - http://breden.org.uk/2008/09/01/home-fileserver-raidz-expansion/) says you can't expand a raidz pool. That is has to be recreated through a bunch of manipulations involving backup of possibly huge amount of data. Is that still the case in the latest dev builds? I ask because I have 1 disk and a sata controller on order that will allow me to add another three disks to the setup. Right now I'm just tinkering (and probably annoying the heck out of these lists) trying to understand the way zfs is intended to be used. I can create and destroy all I want with the two discs I now have to work with but not really understanding how treat partial discs or discs with partitions; wondering to if I should wait until all disks are installed before creating a real zfs pool that will start filling up with data. _______________________________________________ indiana-discuss mailing list [email protected] http://mail.opensolaris.org/mailman/listinfo/indiana-discuss
