Best practices for zpools on zfs
Suppose I have a storage server that runs ZFS, presumably providing
file (NFS) and/or block (iSCSI, FC) services to other machines that
are running Solaris. Some of the use will be for LDoms and zones[1],
which would create zpools on top of zfs (fs or zvol). I have concerns
about variable block sizes and the implications for performance.

How to rename rpool. Is that recommended ?
Hello,
I have a situation where a host, which is booted off its ''rpool'', need
to temporarily import the ''rpool'' of another host, edit some files in
it, and export the pool back retaining its original name ''rpool''. Can
this be done ?
Here is what I am trying to do:
# zpool import -R /a rpool temp-rpool
# zfs set mountpoint=/mnt

FLAG DAY: vdiskadm import/export/convert
I''ve just pushed vdiskadm import/export/convert to the
3.3 vdisk and vbox repos.
You can now import a disk image from a block device or file
to a vdisk, convert (in place) to a different type
of vdisk and export from a vdisk to a block device or file.
I''ve also pushed the full vhd support (sparse and fixed) and
the ability to import a vmdk 1.1 optimized stream file. An

FLAG DAY: vdiskadm translate
I''ve just pushed vdiskadm translate to the 3.3 vdisk repo.
You can now translate data from one virtual disk data
type to another without creating a virtual disk.
This allows the user to use a vmdk file and directly
translate the data into a zvol without having to import
it first to a vdisk and then export it to the zvol.
# vdiskadm help translate

performance with libvirt and kvm
Hi,
I am seeing a performance degradation while using libvirt to start my
vm (kvm). vm is fedora 12 and host is also fedora 12, both with
2.6.32.10-90.fc12.i686. Here are the statistics from iperf :

automatic forced zpool import with unmatched hostid
Hi,
since hostid is stored in the label, "zpool import" failed if the hostid dind''t match. Under certain circonstances (ldom failover) it means you have to manually force the zpool import while booting. With more than 80 LDOMs on a single host it will be great if we could configure the machine back to the old behavior where it didn''t failed, maybe with a /etc/sytem

Narrow escape with FAULTED disks
Nothing like a "heart in mouth moment" to shave tears from your life.
I rebooted a snv_132 box in perfect heath, and it came back up with two FAULTED disks in the same vdisk group.
Everything an hour on Google I found basically said "your data is gone".
All 45Tb of it.
A postmortem of fmadm showed a single disk failed with smart predictive failure.

filesystem mounting fails at boot
Hi
I have an IBM blade with internal harddisks, in hardware RAID1. I've
installed a CentOS 6 64bit on it, everything works just fine.
After the installation, I've presented a vdisk to the blade from an
external SAN (an HP EVA4000), connected through FiberChannel. I've
partitioned the disk, formatted it and mounted it under /store, then
added it to fstab. Everything was fine, until I
