Hello, while browsing around today I stumbled across
Seagate Pipeline HD HDDs lineup (i.e. ST2000VM002).
Did any ZFS users have any experience with them?

If you go the LSI2008 route, avoid raid functionality as it messes up ZFS.
Flash the BIOS to JBOD mode.
You don't even have to do that with the LSI SAS2 cards. They no
longer ship alternate IT-mode firmware

Most enterprise SSDs use something like 30% for spare area. So a
drive with 128MiB (base 2) of flash will have 100MB (base 10) of

128MiB of flash and 128MB

Has there been any change to the server hardware with respect to number of

So is there a way to read these real I/Ops numbers ?
iostat is reporting 600-800 I/Ops peak (1 second sample) for these
7200 RPM SATA drives. If the drives are doing aggregation, then how to
tell what is really going on ?

Hi list,
I've got a pool thats got a single raidz1 vdev. I've just some more disks in

I'd just make a new pool and copy everything

Hi,
One of my colleagues was confused by the output of 'zpool status' on a pool
where a hot spare is being resilvered in after a drive failure:
$ zpool status data
pool: data
state: DEGRADED
status: One or more devices is currently being resilvered. The pool will
continue to function,

I'd love to be able to use modern

So what happens during the txg commit?
For example, if the ZIL is a separate device, SSD for this example, does it
not work like:
1. A sync operation commits the data to the SSD
2. A txg commit happens, and the data from the SSD are written to the
spinning disk

Most of the Intellispeed drives are just 5400rpm; I suppose that this

I have the earlier generation of the 2TB WD RE4 drive in one of my systems.
With Bonwick's diskqual script I saw an average of 119 MB/s across 14

Hi James,
After investigating this problem a bit I'd suggest avoiding deploying

Adam,
Is it known approximately when this bug was introduced? I have a system running
snv_111 with a large
interested in system administration issues.
+1 to those items. I'd also like to hear about how people are maintaining
offsite DR copies of critical data with ZFS. Just send/recv, or something a
little more live?

the disks with EFI labels when you
give a whole disk (no 's#') as an argument.
Hope this helps,
