Hmm .. the only things that I am doing differently (as far as I can tell) is I am using the web GUI to issue the commands and I am running it in a VM (using the pre-buil ones available). I will try using the command line and see if that makes a difference. Maybe I wasn't waiting for it to

Thanks .. I stumbled on the export/import as a solution by acciden (see post below). What confuses me though is that a number of people are reporting that they do not need to do this step. See JMCP and others in this thread: http://www.opensolaris.org/jive/thread.jspa?threadID=50052tstart=0 I

[zfs-discuss] ZFS Home NAS - Configuration Questions

2008-01-24 Thread Kava
Hi, I am new to Solaris, but intrigued by ZFS. I am planning to set up a home NAS (SAMBA/CIFS on ZFS) with my rough plan being to boot SXDE from an IDE drive, then set up a single storage pool with 4 SATA drives (2 x 250GB 2 x 500GB) on a single controller. My main concerns are redundancy

More info from the same guide, page 59: The command also warns you about creating a mirrored or RAID-Z pool using devices of different sizes. While this configuration is allowed, mismatched levels of redundancy result in unused space on the larger device, and requires the -f option to override

2008-01-24 Thread Kava
Hi, Assume that you have a 2-way mirror of small drives that you want to replace with another 2-way mirror of larger drives. What is the best way to do this? If you use the zpool replace command, one at a time on each of the existing old drives, then you will end up wasting the additional

I don't think that is correct. I did it 5 minutes ago and it didn't change the pool size at all. Here is what I did: - create mirrored pool of 2 x 8GB disks - detach one disk - attach/replace with 12Gb disk - detach second disk - attach/replace with second 12GB disk After this, the pool was

Re: [zfs-discuss] Drives of different size

2008-01-24 Thread Kava
I think you can if you create a slice on the larger drive that is equal to the size of the smaller drives (so 300GB) If you just add the whole large drive to the pool, you will lose the extra space. **Apparently if you later replace both of the smaller drives with 2 500 GB drives, the pool

My 2 cents ... read somewhere that you should not be running LVM on top of ZFS ... something about additional overhead. This message posted from opensolaris.org ___ zfs-discuss mailing list zfs-discuss@opensolaris.org

I finally got this to work, but it did not happen automatically. I needed to export then re-import the pool to get it to work. Only then did the additional space appear. Here is what I did: - create 4 x 8GB disks and 1 x 4 GB disks - create RAIDZ pool with 3 x 8GB disks 1 x 4GB - ignore
