Good evening,
I understand that NTFS & VMDK do not relate to Solaris or ZFS, but I was
wondering if anyone has any experience of checking the alignment of data blocks
through that stack?
I have a VMware ESX 4.0 host using storage presented over NFS from ZFS
filesystems (recordsize 4KB). Within
Please excuse my pitiful example. :-)
I meant to say "*less* overlap between virtual machines", as clearly
block "AABB" occurs in both.

That's a good idea, thanks. I get the feeling the remainder won't be zero,
which will back up the misalignment theory. After a bit more digging, it seems
the problem is just an NTFS issue and can be addressed irrespective of
underlying storage system.
I think I'm going to try the process in the
Posting this question again as I originally tagged it onto the end of a series
of longwinded posts of mine where I was having problems replacing a drive.
After dodgy cabling and a few power cuts, I finally got the new drive
resilvered.
Before this final replace, I had 3 x 1TB & 1 x 750GB drives
I knew it would be something simple!! :-)
Now 3.63TB, as expected, and no need to export and import either! Thanks
Richard, that's done the trick.

I'm trying to import a pool into b132 which once had dedup enabled, after the
machine was shut down with an "init 5".
However, the import hangs the whole machine and I eventually get kicked off my
SSH sessions. As it's a VM, I can see that processor usage jumps up to near
100% very quickly, and
Another hang on zpool import thread, I'm afraid, because I don't seem to have
observed any great successes in the others and I hope there's a way of saving
my data ...
In March, using OpenSolaris build 134, I created a zpool, some zfs filesystems,
enabled dedup on them, moved content into them
Absolutely spot on George. The import with -N took seconds.
Working on the assumption that esx_prod is the one with the problem, I bumped
that to the bottom of the list. Each mount was done in a second:

# zfs mount zp/nfs
# zfs mount zp/nfs/esx_dev
# zfs mount zp/nfs/esx_hedgehog
Hi,
I have some strange goings-on with my VM of Solaris Express 11, and I
hope someone can help.
It shares out other virtual machine files for use in ESXi 4.0 (it,
too, runs in there)
I had two disks inside the VM - one for rpool and one for 'vmpool'.
All was fine.
vmpool has some deduped data.
Hi Edward,
Thank you for the feedback. All makes sense.
To clarify, yes, I snapshotted the VM within ESXi, not the filesystems within
the pool. Unfortunately, because of my misunderstanding of how ESXi
snapshotting works, I'm now left without the option of investigating whether

Hi all,
I have a RAID-Z zpool made up of 4 x SATA drives running on Nexenta 1.0.1
(OpenSolaris b85 kernel). It has on it some ZFS filesystems and few volumes
that are shared to various windows boxes over iSCSI. On one particular iSCSI
volume, I discovered that I had mistakenly deleted some fil

whereas all four dd's completed successfully.

That's a good point - I'll try svn94 if I can get my hands on it - any idea
where the download for it is? I've been going round in circles and all I can
come up with are the variants of svn96 - CD, DVD (2 images), DVD (single
image). Maybe that's a sign I should give up for the night!

Ok, used the development 2008.11 (b95) livecd earlier this morning to import
the pool, and it worked fine. I then rebooted back into Nexenta and all is
well. Many thanks for the help guys!

Hi all,
I can confirm that this is fixed too. I ran into the exact same issue yesterday
after destroying a clone:

Hopefully a quick and easy permissions problem here, but I'm stumped and

Thanks Mark. I ran the script and found references in the output to 'aclmode'
and 'aclinherit'. I had in the back of my mind that I've had to mess on with
ZFS ACL's in the past, aside from using chmod with the usual numeric values.
That's given me something to go on. I'll post to cifs-discuss if

I can flesh this out with detail if needed, but a brief chain of events is:

drive names)

Thanks David. Maybe I mis-understand how a replace works? When I added disk E,
and used 'zpool replace [A] [E]' (still can't remember those drive names), I

build the contents of disk E? Sort of like a safer way of doi

2. Power up to test it still works
3. Power down

This process should work, but make sure you don't swap any cables around while
you replace a drive, or you'll run into the situation described in the
