Hi,
I am facing a problem with zfs receive through ssh. As usually, root
can't log on ssh; the log on users can't receive a zfs stream (rights
problem), and pfexec is disabled on the target host (as I understand it
is nowadays default for OI151_a...)
What are the suggestions to solve this?
you could try zfs send'ing to a local file and chmod/chown the file so
that a known local user can access it on the sending server
then on the receiving server you could rsync/ssh into the sending
server grab the file and then zfs receive as root.

Hi,
I've been using zfs for a while but still there are some questions that
have remained unanswered even after reading the documentation so I
thought I would ask them here.
I have learned that zfs datasets can be expanded by adding vdevs. Say
that you have created say a raidz3 pool named

you could always set up an rsync server (not ssh):
man rsyncd.conf
this allows very controlled access, including read-only/specific IP
configurations.

Or send to a named pipe on the remote server that root is recving from.

Do you happen to know how that's done in OI? Otherwise I would have to
move each file one by one to a disk location outside the dataset and
then move it back or zfs send the dataset to another pool of at least
equal size and then zfs receive it back to the expanded pool.

Wouldn't walking the filesystem, making a copy, deleting the original
and renaming the copy balance things?
e.g.
#!/bin/sh
LIST=`find /foo -type d`
for I in ${LIST}
do
cp ${I} ${I}.tmp
rm ${I}
mv ${I}.tmp ${I}
done
or perhaps
# === rewrite.sh ===
#!/bin/bash
$fn=$1

Probably should use find -type f to limit to files and also cp -a to maintain
permissions and ownership. Not sure if the will maintain ACLs.
For the truly paranoid, dont delete the original file so early, rename it, move
the temp file back as the original filename, then compare md5 or sha

For hardlinks, this is bad, indeed, so depending on if you use them or not,
this may or may not be a good idea
This is a perfect way to completely trash your
system. There's no need to 'balance' zfs, over time filesystem
writes will balance roughly over the vdevs, only files
Today I updated OI 151a4 to OI151a7 on hp ML110G6.
KVM works fine. But I want to use virt-manager to manage VM.
So let's me tell the status of virt-manager and libvirt.
Best Regards.

add the ZFS File System Management profile to the backup user. I did

There's a fair bit of overhead to ssh and to zfs send/recive,
You could try to set the crypo algorithm to none if you do not need
encryption.
ssh -c none
Might also be worth trying to see if it is ssh that is slowing you down.

That wont work with the shipped ssh. You could use netcat

If I really needed the extra speed, it would probably be better to spawn a
netcat over ssh so I don't have to modify the target's sshd_config. I

here is my sudoers file:
