I have no way of guessing the effects it would have, but is there a
reason that the filesystem blocks can't be a multiple of the app

Am I correct in assuming that because the ARC cache is fulfilling

That is the state of nirvana you are searching for, no?

Confirmed then that the issue was with the WD10EARS.
I swapped it out with the old one and things look a lot better:

state: DEGRADED
status: One or more devices is currently being resilvered. The pool will
continue to function, possibly in a degraded state.

One of my pools (backup pool) has a disk which I suspect may be going south. I
have a replacement disk of the same size. The original pool was using one of
the partitions towards the end of the disk. I want to move the partition to the
beginning of the disk on the new disk.

Thanks Roy for your reply.
I actually waited a little more than an hour, but I'm still going to wait a
little longer following your suggestion and a little hunch of mine. I just
found out that this new WD10EARS is one of the new 4k disks. I believed that
only the 2TB models where 4k.
See:
BEFORE
ZFS first does a scan of indicies and such, which requires lots of seeks. After
that, the resilvering starts. I guess if you give it an hour, it'll be done

Hello everyone,
As one of the steps of improving my ZFS home fileserver (snv_134) I wanted
to replace a 1TB disk with a newer one of the same vendor/model/size because
this new one has 64MB cache vs. 16MB in the previous one.
The removed disk will be use for backups, so I thought it's better off t

Hi all
I've been playing a little with dedup, and it seems it needs a truckload of
memory, something I don't have on my test systems. Does anyone have performance

A RaidZ-2 pool with one missing disk offers the same failure resilience as a
healthy RaidZ1 pool (no data loss when one disk fails). I had initially wanted
to do single parity raidz pool (5disk), but after a

Search the archives. This dead horse gets beaten about every 6-9 months or so.

Is there anything anybody has to advise? Will I be better of copying each
folder into its own FS from source pool? How about removal of the stuff that's
now in this FS? How long will the removal of 770GB data containing 6millions
files take?

This actually depends on the failmode property setting in your pools.
The default is panic, but it also might be wait or continue - see
zpool(1M) man page for more details.
