Hello,
I try to create a zfs file system according to
Creating a Basic ZFS File System section of
Creating a Basic ZFS File System document of SUN.
The problem is that the device has a ufs filesystem the partiotion
I am trying to work with; it is in fact empty and does not contain any

Hi
I have 2 questions on use of ZFS.
How do I ensure I have site redundancy using zfs pools, as I see it we only
ensures mirrors between 2 disks. I have 2 HDS on one each site and I want to

able to loose the one of them and my
Ian,
The first error is correct in that zpool-create will not, unless
forced, create a file system if it knows that another filesystem
presides in the target vdev.
The second error was caused by your removal of the slice.
What I find discerning is that the zpool created.
Can you provide the

Still ... I don't think a core file is appropriate. Sounds like a bug is
in order if one doesn't already exist. (zpool dumps core when missing
devices are used perhaps?)

You can add more disks to a pool that is in raid-z you just can't
add disks to the existing raid-z vdev.
cd /usr/tmp
mkfile -n 100m 1 2 3 4 5 6 7 8 9 10
zpool create t raidz /usr/tmp/1 /usr/tmp/2 /usr/tmp/3

zfs list t
zpool add -f t raidz2 /usr/tmp/4 /usr/tmp/5 /usr/tmp/6

Hi Luke,
We've been using MPXIO (STMS) with ZFS quite solidly for the past few
months. Failover is instantaneous when a write operations occurs
after a path is pulled. Our environment is similar to yours, dual-FC
ports on the host, and 4 FC ports on the storage (2 per controller).
Depending on
One of our file servers internally to Sun that reproduces this running nv53
here is the dtrace output:
unix`mutex_vector_enter+0x120
zfs`metaslab_group_alloc+0x1a0
zfs`metaslab_alloc_dva+0x10c
zfs`metaslab_alloc+0x3c

Hi Doug,
The configuration is a T2000 connected to a StorageTek FLX210 array
via Qlogic QLA2342 HBAs and Brocade 3850 switches. We currently RAID-Z
the LUNs across 3 array volume groups. For performance reasons we're
in the process of changing to striped zpools across RAID-1 volume
groups. The

What about adding a whole new RAID-Z vdev and dynamicly stripe across
the RAID-Zs? Your capacity and performance will go up with each
RAID-Z vdev you add.
Thanks, that's an interesting suggestion.
Have you tried using the automounter as suggested
Hi Luke,
That's really strange. We did the exact same thing moving between two
hosts (export/import) and it took maybe 10 secs. How big is your
zpool?

I, too, experienced a long delay while importing a zpool on a second machine. I
do not have any filesystems in the pool. Just the Solaris 10 Operating system,
Emulex 10002DC HBA, and a 4884 LSI array (dual attached).
