Hi All,
I'm interested in exploring the logic that selects the vdev for a newly
created file. I've spent some time in the metaslab.c file but this appears
to be weighting slab selection within a vdev .not really the logic I'm
looking for. I expect vdev selection is a simple algorithm that

I have 4 disks on a SAN that I have created one pool on (IBM-ES7), when I

/downloads I can still see the data.. then when I do a zfs mount -a it says
cannot mount '/downloads': directory is not empty.

Hi Duff,
... I expect vdev selection is a simple algorithm
that rotates through vdevs with some additional logic to handle the case
where the vdev is full.
The vdev selection policy is in metaslab_alloc_dva(). You are right that
it is a simple algorithm that rotates through the vdevs. Apart
There is an open issue/bug with ZFS and EMC PowerPath for Solaris 10 in x86/x64
space. My customer encountered the issue back in April 2007 and is awaiting
the patch. We're expecting an update (hopefully a patch) by the end of July
2007.
As I recall, it did involve CX arrays and trespass

Hello Stuart,
Looks like crash dumped went ok.
Check logs after system booted up again if there's a warning that
there's no enough space in /var/crash/x4500gc to save crashdump.
When using zfs on a file servers crashdumps usually will be almost
of server's memory size...

Hi Robert,
It should work. We have not had the time or resources to test it (we are
busy qualifying the 2530 (SAS array) with an upcoming MPxIO enabled MPT
driver and SATA drive support).
I do not know if MPxIO will claim raw drives or nottypically there

I have a fresh Solaris 10/6 install. My disk have 20Gb but I used only
10GB for the base solaris installation and home directory.
I have 10GB free without any partition.
I would like to use my free space to store my zones using zfs filesystem.
In example:
/zones
/zone/zona1
/zone/zone2

Hi folks,
One of the things I'm really hanging out for is the ability to evacuate
the data from a zpool device onto the other devices and then remove the
device. Without mirroring it first etc. The zpool would of course shrink
in size according to how much space you just took away.

At the moment once a device is in a zpool, it's stuck there. That's a
problem. What sort of time frame are we looking at until it's possible
to remove LUNs from zpools?
It might be in OpenSolaris around the end of the (calendar) year. That's
just a rough guess though.
