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

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.

Can I create a mirror for a root rpool?
On Solaris 10 If I install using ZFS root on only one drive is there a way
to add another drive as a mirror later? Sorry if this was discussed
already. I searched the archives and couldn''t find the answer. Thank you.

zfs allow does not work for rpool
I am trying to give a general user permissions to create zfs filesystems in the rpool.
zpool set=delegation=on rpool
zfs allow <user> create rpool
both run without any issues.
zfs allow rpool reports the user does have create permissions.
zfs create rpool/test
cannot create rpool/test : permission denied.
Can you not allow to the rpool?

Space usage
I''m just uploading all my data to my server and the space used is much more than what i''m uploading;
Documents = 147MB
Videos = 11G
Software= 1.4G
By my calculations, that equals 12.547T, yet zpool list is showing 21G as being allocated;

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

incremental backup with zfs to file
FULL backup to a file
zfs snapshot -r rpool at 0908
zfs send -Rv rpool at 0908 > /net/remote/rpool/snaps/rpool.0908
INCREMENTAL backup to a file
zfs snapshot -i rpool at 0908 rpool at 090822
zfs send -Rv rpool at 090822 > /net/remote/rpool/snaps/rpool.090822
As I understand the latter gives a file with changes between 0908 and
090822. Is this correct?
How do I restore those files? I know

Strange behavior of b151a and .zfs directory
Hello,
after upgrade to Sol11Express I''ve noticed kind of strange behavior of .zfs directory of any ZFS filesystem. Go into the .zfs directory and type `find . -type f'' for the first time after you''ve mounted the file-system. It''ll show nothing. Type it second time and you will get expected list of files from all the snapshots.
Is this expected or is it a bug? I

zfs raidz questions
Hi there,
i''m building a small NAS with 5x1TB Disks. The disks contains at the moment some data, ntfs as the fs and aren''t a raid.
Now my im wondering if its possible to add the parity later. So that i add step by step one disk to the pool. And when i add the last disk, i enable the parity.
(i have only one another 1 tb disk to backup the files)
Thank you for you replies and

Saving data across install
I installed a Solaris 10 development box on a 500G root mirror and later I
received some smaller drives. I learned from this list its better to have
the root mirror on the smaller small drives and then create another mirror
on the original 500G drives so I copied everything that was on the small
drives onto the 500G mirror to free up the smaller drives for a new install.
After my install

Killing an EFI label
Since this seems to be a ubiquitous problem for people running ZFS, even
though it''s really a general Solaris admin issue, I''m guessing the
expertise is actually here, so I''m asking here.
I found lots of online pages telling how to do it.
None of them were correct or complete. I think. I seem to have
accomplished it in a somewhat hackish fashion, possibly not

zpool detach on non-mirrored drive
I''m using zfs not to have access to a fail-safe backed up system, but to easily manage my file system. I would like to be able to, as I buy new harddrives, just to be able to replace the old ones. I''m very environmentally concious, so I don''t want to leave old drives in there to consume power as they''ve already been replaced by larger ones. However, ZFS

"no pool_props" for OpenSolaris 2009.06 with old SPARC hardware
Hi,
yesterday evening I tried to upgrade my Ultra 60 to 2009.06 from SXCE snv_98.
I can''t use AI Installer because OpenPROM is version 3.27.
So I built IPS from source, then created a zpool on a spare drive and installed OS 2006.06 on it
To make the disk bootable I used:
installboot -F zfs /usr/platform/`uname -i`/lib/fs/zfs/bootblk /dev/rdsk/c0t1d0s0

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!

Accidentally added disk instead of attaching
Hi,
I wanted to add a disk to the tank pool to create a mirror. I accidentally used zpool add ? instead of zpool attach ? and now the disk is added. Is there a way to remove the disk without loosing data? Or maybe change it to mirror?
Thanks,
Martijn

zpool create using whole disk - do I add "p0"? E.g. c4t2d0 or c42d0p0
I have seen conflicting examples on how to create zpools using full disks. The zpool(1M) page uses "c0t0d0" but OpenSolaris Bible and others show "c0t0d0p0". E.g.:
zpool create tank raidz c0t0d0 c0t1d0 c0t2d0 c0t3d0 c0t4d0 c0t5d0
zpool create tank raidz c0t0d0p0 c0t1d0p0 c0t2d0p0 c0t3d0p0 c0t4d0p0 c0t5d0p0

SSD over 10gbe not any faster than 10K SAS over GigE
GigE wasn''t giving me the performance I had hoped for so I spring for some 10Gbe cards. So what am I doing wrong.
My setup is a Dell 2950 without a raid controller, just a SAS6 card. The setup is as such
:

to create the raidz I did a simple zpool create raidz SSD c1xxxxx c1xxxxxx c1xxxxx. I have

Can this be done?
I currently have a 7x1.5tb raidz1.
I want to add "phase 2" which is another 7x1.5tb raidz1
Can I add the second phase to the first phase and basically have two
raid5''s striped (in raid terms?)
Yes, I probably should upgrade the zpool format too. Currently running
snv_104. Also should upgrade to 110.
If that is possible, would anyone happen to have the simple command
