Bug in "zpool history"
Hi,
I was playing around with NexentaCP and its zfs boot facility. I tried
to figure out how what commands to run and I ran zpool history like
this
# zpool history
2007-06-20.10:19:46 zfs snapshot syspool/rootfs at mysnapshot
2007-06-20.10:20:03 zfs clone syspool/rootfs at mysnapshot syspool/myrootfs
2007-06-20.10:23:21 zfs set bootfs=syspool/myrootfs syspool
As you can see it says I did a

Excellent idea using kernel sources! A lot of different files...
I will use this to create indicative benchmarks for different scenarios...

Wishlist items
I''ve been saving up a few wishlist items for zfs. Time to share.
1. A verbose (-v) option to the zfs commandline.
In particular zfs sometimes takes a while to return from zfs snapshot -r
tank/volumes at foo in the case where there are a great many iscsi shared
volumes underneath. A little progress feedback would go a long way. In
general I feel the zfs tools lack sufficient feedback

Unable to convert vm
I am unable to convert a vm using virt-v2v. From the trace and debug
logs I am unable to understand the cause of the problem. I assume it is
a permission or configuration issue but I don't know where to start looking.
The following command was issued:

rsync --delete with empty source folder for fast snapshot deletion: Permissions of hardlinked files are changed to 644. Workaround?
So I decided to do a quick test using the Linux kernel source tree since
it has lots of files. I duplicated a tree, used 'find . -type f -exec
chmod 444 {} +' to make read only files for rsync to want to chmod, then
used cp -al to make several duplicate trees using hard linked files. An
rm -rf on one such tree took .97 seconds while an rsync deletion took
1.25 seconds. Clearly I

trying to get a game called EUO to run

Comments requested on "changedFiles" function
In a number of places internal to R, we need to know which files have
changed (e.g. after building a vignette). I've just written a general
purpose function "changedFiles" that I'll probably commit to R-devel.
Comments on the design (or bug reports) would be appreciated.
The source for the function and the Rd page for it are inline below.

The ZFS MOS and how DNODES are stored
ZFS documentation lists snapshot limits on any single file system in a pool at 2**48 snaps, and that seems to logically imply that a snap on a file system does not require an update to the pool?s currently active uberblock. That is to say, that if we take a snapshot of a file system in a pool, and then make any changes to that file system, the copy on write behavior induced by the changes will

ipp2p: error loading kernel module
Hi,
I get this error when trying to insmod the ipp2p kernel module:

Kernel version 2.6.20.4
iptables version: 1.3.5
ipp2p version: 0.8.2 (latest)
Anyone tried ipp2p with kernel 2.6.20?

Where does the "prompt come from"
Hi All !
I have a little question about the shell that is run when establishing a
connection towards an SSH server.
The client(OpenSSH) displays a prompt(as usual) when a command is executed,
but my question is, where does the prompt come from.
Is it sent by the remote shell or is it handled in the client ??
The reason I ask is that we have developed a product that redirects

zfs object sets and datasets
Hi All,
I am looking at trying to understand the conceptual model of how data is
grouped and partitioned within a storge pool. In looking at the on disk
document that Tabriz sent out a few weeks ago I see that object sets are
the grouping which ZFS uses to group objects that are related.
Specifially to aid in format and layout of like objects in to a set.
So, for example 1 potential object

libvirt error messages
Hello,
I am experimenting with libvirt for my diploma. I set up an environment,
where I can stop, resend, generate messages for libvirt.
I am capable also standing between client and server and analyze the number
of current procedure and decide what to do next ( I mean rpc procedure).
So, for example I want to always drop creating snapshots and send an error

zfs diff performance
I had high hopes of significant performance gains using zfs diff in
Solaris 11 compared to my home-brew stat based version in Solaris 10.
However the results I have seen so far have been disappointing.
Testing on a reasonably sized filesystem (4TB), a diff that listed 41k
changes took 77 minutes. I haven''t tried my old tool, but I would
expect the same diff to take a couple of

I can see that Asterisk executes mpg123 properly (I think)
