Finding where dedup''d files are
Is there an easy way to find out what datasets have dedup''d data in
them. Even better would be to discover which files in a particular
dataset are dedup''d.
I ran
# zdb -DDDD
which gave output like:
index 1055c9f21af63 refcnt 2 single DVA[0]=<0:1e274ec3000:2ac00:STD:1>
[L0 deduplicated block] sha256 uncompressed LE contiguous unique
unencrypted 1-copy size=20000L/20000P

dedup testing?
Hi all
Has anyone done any testing with dedup with OI? On opensolaris there is a nifty "feature" that allows the system to hang for hours or days if attempting to delete a dataset on a deduped pool. This is said to be fixed, but I haven''t seen that myself, so I''m just wondering...
I''ll get a 10TB test box released for testing OI in a few weeks, but before

sharenfs=off, but still being shared?
I noticed an oddity on my 2008.05 box today.
Created a new zfs file system that I was planning to nfs share out to an old FreeBSD box, after I put sharenfs=on for it, I noticed there was a bunch of others shared too:
-bash-3.2# dfshares -F nfs

lazy zfs destroy
OK I have a very large zfs snapshot I want to destroy. When I do this, the system nearly freezes during the zfs destroy. This is a Sun Fire X4600 with 128GB of memory. Now this may be more of a function of the IO device, but let''s say I don''t care that this zfs destroy finishes quickly. I actually don''t care, as long as it finishes before I run out of disk space.

cross platform (freebsd) zfs pool replication
Hi,
I have two servers running: freebsd with a zpool v28 and a nexenta (opensolaris b134) running zpool v26.
Replication (with zfs send/receive) from the nexenta box to the freebsd works fine, but I have a problem accessing my replicated volume. When I''m typing and autocomplete with tab key the command cd /remotepool/us (for /remotepool/users) I get a panic.

Compatibility of Hitachi Deskstar 7K3000 HDS723030ALA640 with ZFS
Greetings,
Quick question:
I am about to acquire some disks for use with ZFS (currently using zfs-fuse
v0.7.0). I''m aware of some 4k alignment issues with Western Digital
advanced format disks.
As far as I can tell, the Hitachi Deskstar 7K3000 (HDS723030ALA640) uses
512B sectors and so I presume does not suffer from such issues (because it
doesn''t lie about the physical layout

ZFS send/receive to Solaris/FBSD/OpenIndiana/Nexenta VM guest?
Hello,
I''m debating an OS change and also thinking about my options for data
migration to my next server, whether it is on new or the same hardware.
Migrating to a new machine I understand is a simple matter of ZFS
send/receive, but reformatting the existing drives to host my existing
data is an area I''d like to learn a little more about. In the past I''ve

I can''t seem to get the pool to export...
root at nas:~# zpool export -f raid
cannot export ''raid'': pool is busy
I''ve disabled all the services I could think of. I don''t see anything accessing it. I also don''t see any of the filesystems mounted with mount or "zfs mount". What''s the deal? This is not the rpool, so I''m not booted off it or anything like that.

Reboots when importing old rpool
I have a fresh install of Solaris 11 Express on a new SSD. I have inserted the old hard disk, and tried to import it, with:
# zpool import -f <long id number> Old_rpool
but the computer reboots. Why is that? On my old hard disk, I have 10-20 BE, starting with OpenSolaris 2009.06 and upgraded to b134 up to snv_151a. I also have a WinXP entry in GRUB.
This hard disk is partitioned, with a

7-disk raidz achieves 430 MB/s reads and 220 MB/s writes on a $1320 box
I figured the following ZFS ''success story'' may interest some readers here.
I was interested to see how much sequential read/write performance it would be
possible to obtain from ZFS running on commodity hardware with modern features
such as PCI-E busses, SATA disks, well-designed SATA controllers (AHCI,
SiI3132/SiI3124). So I made this experiment of building a fileserver by

Verbose Information from "zfs send -v <snapshot>"

Also on Solaris 10u6 I don''t get any output at all - is this a bug?

Huge difference in reporting disk usage via du and zfs list. Fragmentation?
Do we have enormous fragmentation here on our X4500 with Solaris 10, ZFS Version 10?
What except zfs send/receive can be done to free the fragmented space?
One ZFS was used for some month to store some large disk images (each 50GByte large) which are copied there with rsync. This ZFS then reports 6.39TByte usage with zfs list and only 2TByte usage with du.
The other ZFS was used for similar

ZFS and TRIM
My google-fu is coming up short on this one... I didn''t see that it had
been discussed in a while ...
What is the status of ZFS support for TRIM?
For the pool in general...
and...
Specifically for the slog and/or cache???

ashift and vdevs
zdb -C shows an shift value on each vdev in my pool, I was just wondering if
it is vdev specific, or pool wide. Google didn''t seem to know.
I''m considering a mixed pool with some "advanced format" (4KB sector)
drives, and some normal 512B sector drives, and was wondering if the ashift
can be set per vdev, or only per pool. Theoretically, this would save me
some size on
