Help replacing dual identity disk in ZFS raidz and SVM mirror
Hi,
We have a number of 4200''s setup using a combination of an SVM 4 way mirror and a ZFS raidz stripe.
Each disk (of 4) is divided up like this
/ 6GB UFS s0 
Swap 8GB s1
/var 6GB UFS s3
Metadb 50MB UFS s4
/data 48GB ZFS s5 
For SVM we do a 4 way mirror on /,swap, and /var
So we have 3 SVM mirrors
    d0=root (sub mirrors d10, d20, d30, d40)
    d1=swap (sub mirrors d11, d21,d31,d41)

How do you "re-attach" a 3 disk RAIDZ array to a new OS installation?
Hi,
I''m completely new to Solaris, but have managed to bumble through installing it to a single disk, creating an additional 3 disk RAIDZ array and then copying over data from a separate NTFS formatted disk onto the array using NTFS-3G.
However, the single disk that was used for the OS installation has since died (it was very old) and I have had to reinstall 2008.11 from scratch onto a

borrow disk from raidz?
Hi all!
I got a short question regarding data migration:
I want to copy my data (~2TB) from an old machine to a new machine with a
new raidz1 (6 disks x 1,5TB each ). Unfortunately this is not working
properly via network due to various (driver) problems on the old machine.
So my idea was:
to borrow one disk from the new raidz1 (leaving the raid in degraded, but
working status)
attach the now

Mixing RAIDZ and RAIDZ2 zvols in the same zpool
I have a customer who has implemented the following layout:  As you can 
see, he has mostly raidz zvols but has one raidz2 in the same zpool.  
What are the implications here?  Is this a bad thing to do? Please 
elaborate.
Thanks,

raidz mismatched disk sizes
Is it possible to build a raidz with different disk sizes?  If so, are you limited to the
size of the smallest disk (*ndisks)?

raidz "ZFS Best Practices" wiki inconsistency
<http://www.solarisinternals.com/wiki/index.php/ZFS_Best_Practices_Guide#RAID-Z_Configuration_Requirements_and_Recommendations>
says that the number of disks in a RAIDZ should be (N+P) with
N = {2,4,8} and P = {1,2}.
But if you go down the page just a little further to the thumper
configuration examples, none of the 3 examples follow this recommendation!

Proposal expand raidz
Greetings
Have used zfs raidz for while and question rised is it possible to expand raidz with additional disks.
Got answer pool yes but raidz "group" no.
So very high level idea for you , maybe already know.
And i''m not detail level expert of zfs so here might be "trivial" things for you.
So could add operation enhanced so that it allow to add additional

ZFS Filesystem Recovery on RAIDZ Array
This day went from usual Thursday to worst day of my life in the span of about 10 seconds.  Here''s the scenario:
2 Computer, both Solaris 10u8, one is the primary, one is the backup.  Primary system is RAIDZ2, Backup is RAIDZ with 4 drives.  Every night, Primary mirrors to Backup using the ''zfs send'' command. The Backup receives that with ''zfs recv

RAIDZ v. RAIDZ1
So, I took four 1.5TB drives and made RAIDZ, RAIDZ1 and RAIDZ2 pools.  The sizes for the pools were 5.3TB, 4.0TB, and 2.67TB respectively.  The man page for RAIDZ states that "The raidz vdev type is an alias for raidz1."  So why was there a difference between the sizes for RAIDZ and RAIDZ1?  Shouldn''t the size be the same for "zpool create raidz ..." and "zpool

ZFS mirror to RAIDz?
Hi all,
I currently have four drives in my OpenSolaris box.  The drives are split into two mirrors, one mirror containing my rpool (disks 1 & 2) and one containing other data (disks 2 & 3).
I''m running out of space on my data mirror and am thinking of upgrading it to two 2TB disks. I then considered replacing disk 2 with a 2TB disk and making a RAIDz from the three new drives.

raidz question
Hi, I have E450 with 20 SCSI disks. 1 disk is used as a boot disk with critical filesystems like /, /usr, /var, etc. then othe 19 disks are configured with ZFS in raidz. Are there any significant performance implications of using raidz with such a large number of disks? Would there much to be gained in performance if I were to simply configure striping across those disks, instead of raidz?

Zpool with raidz+mirror = wrong size displayed?
Hi,
I installed a zpool containing of
zpool
__mirror
____disk1 500gb
____disk2 500gb
__raidz
____disk3 1tb
____disk4 1tb
____disk5 1tb
It works fine, but it displays the wrong size (terminal -> zpool list). It should be 500gb (mirrored) + 2TB (3TB raidz) = 2,5 TB, right? But it displays it has 3,17TB diskspace available.
I first created the mirror and then added the raidz to it (zpool add

General question about ZFS and RAIDZ
Hello to the forum,
with my general question about ZFS and RAIDZ I want the following to know:
Must all harddisks for the storage pool have the same capacity or is it possible to use harddisks with different capacities?
Many thanks for the answers.
Best regards

Convert raidz
Hi
Is it possible to convert live 3 disks zpool from raidz to raidz2
And is it possible to add 1 new disk to raidz configuration without backups and recreating zpool from cratch.

preview zfs port to grub2 + raidz
Hi zfsers
Just wanted to ping the list since one of the osunix/grub devs has been 
working hard at porting zfs to grub2.  I don''t think he''s subscribed to 
zfs-discuss so quoting his original email and cc''ing him.

Expanding a raidz vdev in zpool
Hello All,
I have a zpool that consists of 2 raidz vdevs (raidz1-0 and raidz1-1). The
first vdev is 4 1.5TB drives. The second was 4 500GB drives. I replaced the
4 500GB drives with 4 3TB drives.
I replaced one at time, and resilvered each. Now the process is complete, I
expected to have an extra 10TB (4*2.5TB) of raw space, but it''s still the
same amount of space.
I did an export and

convert raidz from osx
I am converting a 4 disk raidz from osx to opensolaris. And I want to keep the data intact.
I want zfs to get access to the full disk instead of a slice.
I believe like c8d0 instead off c8d0s1.
I wanted to do this 1 disk at a time and let it resilver.
what is the proper way to do this.
I tried, I believe from memory : zpool replace -f rpool c8d1s1 c8d1
but it didn''t let me do that.
then I
