ZDB returning strange values
Hello all, I have a question about what output "ZDB -dddddd" should
produce in L0 DVA fields. I expected there to be one or more
same-sized references to data blocks stored in top-level vdevs
(one vdev #0 in my 6-disk raidz2 pool), as confirmed by the source:

zpool upgrade and zfs upgrade behavior on b145

Pool ''rpool'' is already formatted using the current version.

The file systems have been upgraded according to "zfs get version rpool"
Looks ok to me.
However, I now get an error when I run zdb -D. I can''t remember exactly
when I turned dedup on, but I moved some data on rpool, and "zpool list"

Inconcistancies with scrub and zdb
...istake was to assume the counters were in error on the second
mirror, and so I zeroed out the counters with zpool clear. OK, so now I
scrub the pool, and no checksum errors were found on either side of the
mirror. Huh?!? What about those two checksum errors on the first
mirror. OK, so I run zdb on the pool, and if finds scads of errors:
Traversing all blocks to verify checksums and verify nothing leaked ...

zpool versioning
Hi,
I was wondering if anyone would know if this is just an accounting-type
error with the recorded "version=" stored on disk, or if there
are/could-be any deeper issues with an "upgraded" zpool?
I created a pool under a Sol10_x86_u3 install (11/06?), and zdb correctly
reported the pool as a "version=3" pool. I reinstalled the OS with a u4
(08/07), ran zpool grade, was told I successfully upgraded from version 3
to version 4, but zdb reported "version=3". I unmounted the zfs,
remounted, and zdb still reported "version=3&qu...

zdb assertion failure/zpool recovery
...i,
I have a corrupt pool, which lives on a .vdi file of a VirtualBox. IIRC
the corruption (i.e. pool being not importable) was caused when I killed
virtual box, because it was hung.
This pool consists of a single vdev and I would really like to get some
files out of that thing. So I tried running zdb, but this fails with an
assertion failure:
Assertion failed: object_count == usedobjs (0xce == 0xcd), file
../zdb.c, line 1215
Abort (core dumped)
The core file consists of 107 threads. The thread with the assertion

(gang?)block layout question, and how to decipher ZDB output?

I''m "playing" with ZDB again on another test system,

ZFS recovery tools
...antagonizing time this took, I was surprised to
learn how undocumented the tools and options for ZFS recovery we''re. I managed to recover thanks
to some great forum posts from Victor Latushkin, however without his posts I would still be crying
at night...
I think the worst example is the zdb man page, which all it does is to ask you to "contact a Sun
Engineer", as this command is for experts only. What the hell? I don''t have a support contract for
my home machines... I don''t feel like this is the right way to go for an open source project...
A penny for any...

invalid vdev configuration after power failure
What does it mean for a vdev to have an invalid configuration and how
can it be fixed or reset? As you can see, the following pool can no
longer be imported: (Note that the "last accessed by another system"
warning is because I moved these drives to my test workstation.)
~$ zpool import -f pool0

zpool import is trying to tell me something...
...Somebody is trying to tell me something, but I''m not receiving. All four disks (there were only ever four in the array, since creation until the present) appear present, are readable (via dd if=...), have sane looking uberblock arrays, and give more or less sane looking answers to "zdb -l /dev/dsk/..."; the whole output of the latter is a bit much to paste here but I can if somebody thinks it would be useful. zdb with no arguments also enumerates the pool in the list and looks saneish.
Other zdb commands apparently do not work, hopefully due to the same root cause.

Kernel panic on import / interrupted zfs destroy
...tion, which then became another panic / reboot loop.
I was able to get in with milestone=none and delete the zfs cache, but now I have a new problem: Any attempt to import the pool results in a panic. I have tried from my snv_134 install, from the live cd, and from nexenta. I have tried various zdb incantations (with aok=1 and zfs:zfs_recover=1), to no avail - these error out after a few minutes. I have even tried another controller.
I have zdb -e -bcsvL running now from 134 (without aok=1) which has been running for several hours. Can zdb recover from this kind of situation (with a half-d...

Single-disk rpool with inconsistent checksums, import fails
Hello all,
I have an oi_148a PC with a single root disk, and since
recently it fails to boot - hangs after the copyright
message whenever I use any of my GRUB menu options.
Booting with an oi_148a LiveUSB I had around since
installation, I ran some zdb traversals over the rpool
and zpool import attempts. The imports fail by running
the kernel out of RAM (as recently discussed in the
list with Paul Kraus''s problems).
However, in my current case, the rpool has just 11.2Gb
allocated with 8.7Gb "available". So almost all of it

ZFS Space Map optimalization
...thinking about disabling checksums. All metadata are written in 2 copies,
so when I have compression=on do I need checksums ?
Does zfs will try to read second block when zio_decompress_data will return error ?
Is there other way to check space map compression ratio ?
Now I''m using "#zdb -bb pool" but it takes hours.

Kernel panic on zfs import
...39;t care about rpool. :-(
If I boot from hard disk, the system begins importing zfs pools; once
it''s imported everything I usually have enough time to log in before
it panics. If I boot from CD and ''zfs import -f tank'', it panics.
I''ve just started a ''zdb -e tank'' which I found on the intertubes
here: http://opensolaris.org/jive/thread.jspa?threadID=49020. Zdb
seems to be ... doing something. Not sure _what_ it''s doing, but it
can''t be making things worse for me right?

How to know the recordsize of a file
-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1
I would like to know the blocksize of a particular file. I know the
blocksize for a particular file is decided at creation time, in fuction
of the write size done and the recordsize property of the dataset.
How can I access that information?. Some zdb magic?.
