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
the replaced
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.
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
# zfs mount zp/nfs
# zfs mount zp/nfs/esx_dev
# zfs mount zp/nfs/esx_hedgehog
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
Please excuse my pitiful example. :-)
I meant to say *less* overlap between virtual machines, as clearly
block AABB occurs in both.

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

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

I have a RAID-Z zpool made up of 4 x SATA drives running on Nexenta 1.0.1

volume, I discovered that I had mistakenly deleted some
Ah-ha! That certainly looks like the same issue Miles - well spotted! As it

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

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
