I am confused by the numerical value of compressratio. I copied a
compressed ZFS filesystem that is 38.5G in size (zfs list USED and
REFER value) and reports a compressratio value of "2.52x" to an
uncompressed ZFS filesystem and it expanded to 198G. So why is the
compressratio 2.52 rather than 198/
So for a general purpose fileserver using standard SATA connectors on the

Thanks Bob, that's good advice. So, before I open my case, I've currently got 3
SATA drives all the same model, so how do I know which one is plugged into
which SATA connector on the motherboard? Is there a command I can issue which
gives identifying info that includes the disk id AND the SATA c
Jeff,
No easy way exists to convert this configuration to a mirrored
configuration currently.
If you had two more disks, you could use zpool attach to create
a two-way, two disk mirror. See the output below.
A more complicated solution is to create two files that are the size of
your existing di
A colleague told me IET is not longer an ongoing project, so it's obsoleted.
There's another new linux iscsi target:
ISCSI-SCST is a forked (with all respects) version of IET with updates to work
over SCST as well as with many improvements and bugfixes.

Hi,
Is it possible to convert a zfs pool from a concatenation of 2 disks to
a 2 way mirror without backing up the data, re-creating the pool and
restoring it. i.e
diskA,diskB > mirror(diskA,diskB)
Thanks,
Jeff

Hi, Experts:
A customer has X4500 and the boot drives mirrored (c5t0d0s0 and
c5t4d0s0) by SVM,
The ZFS uses the two other partitions on these two drives(c5t0d0s3 and
c5t4d0s3).
If we need to replace the disk drive c5t0d0, do we need to do anything
on the ZFS

Thanks myxiplx for the info on replacing a faulted drive. I think the X4500 has
LEDs to show drive statuses so you can see which physical drive to pull and
replace, but how does one know which physical disk to pull out when you just
have a standard PC with drives directly plugged into on-motherb
That's excellent news for me. I think Sun should think about a solution as
everything today is somewhat linked to VMWare.
I am no expert about Linux and VMWare, can someone tell me step by step
(assuming that I do not know anything which is kinda true)
How to apply the path mentioned at

I had similar problems replacing a drive myself, it's not intuitive exactly
which ZFS commands you need to issue to recover from a drive failure.
I think your problems stemmed from using -f. Generally if you have to use
that, there's a step or option you've missed somewhere.
However I'm not
