ok, I think I did figure out what is the problem
well what zpool does for that emc powerpath is it takes parition 0 from disk and
is trying to attach it to my pool, so when I added emcpower0a I got the
following:

yeah it does something funky that I did not expect, zpool seems like its taking
slice 0 of that emc lun rather than taking the whole device...
so when I did create that lun, I formated disk and it looked like this:
format verify

Hi,
I have been given the task to research converting our vxfs/vm file systems and
volumes to zfs. The volumes are attached to an EMC Clariion running raid-5, and
raid 1_0. I have no test machine, just a migration machine that currently hosts
other things. It is possible to setup a zfs file
zpool replace == zpool attach + zpool detach
It is not a good practice to detach and then attach as you
are vulnerable after the detach and before the attach completes.
It is a good practice to attach and then detach. There is no
practical limit to the number of sides of a mirror in ZFS.

It's my belief this mainly aids scanning metadata. my

I need help on this customers issue. I appreciate any help that
If i put the database in hotbackup mode,then i will have to ensure
that the filesystem is consistent as well.So, you are saying that
taking a ZFS snapshot is the only method to guarantee consistency in
the filesystem since it flushes all the buffers to the filesystem , so
its consistent.
I managed to correct the problem by writing a script inspired
by Chris Gerhard's blog that did a zfs send | zfs recv. Now
that things are back up, I have a couple of lingering questions:
1) I noticed that the filesystem size information is not the
same between the src and dst filesystem
Hello Richard,
RE But I am curious as to why you believe 2x CF are necessary?
RE I presume this is so that you can mirror. But the remaining memory

I was thinking about mirroring - it's not clear from the comment above
2) Following Chris's advice to do more with snapshots, I
played with his cron-triggered snapshot routine:

Now, after a couple of days, zpool history shows almost
100,000 lines of output (from all the snapshots and

On Solaris x86, does zpool (or anything) support PATA (or SATA) IDE
SMART data? With the Predictive Self Healing feature, I assumed that
Solaris would have at least some SMART support, but what I've googled so
far has been discouraging.

Prior to the above work, we only monitored disks on Thumper (x4500)

I'd love to be able to server zvols out as SCSI or FC
targets. Are
there any plans to add this to ZFS? That would be
amazingly awesome.
Can one use a spare SCSI or FC controller as if it were a target?
Even if the hardware is capable, I don't see what you describe as
a ZFS thing really; it

we'd need an FC or SCSI target mode driver in Solaris .. let's just
say we
used to have one, and leave it mysteriously there. smart idea though!
