4k sector support in Solaris 11?
If I want to use a batch of new Seagate 3TB Barracudas with Solaris 11,
will zpool let me create a new pool with ashift=12 out of the box or will
I need to play around with a patched zpool binary (or the iSCSI loopback)?

Speed question: 8-disk RAIDZ2 vs 10-disk RAIDZ3
I currently am getting good speeds out of my existing system (8x 2TB in a
RAIDZ2 exported over fibre channel) but there''s no such thing as too much
speed, and these other two drive bays are just begging for drives in
them.... If I go to 10x 2TB in a RAIDZ3, will the extra spindles increase
speed, or will the extra parity writes reduce speed, or will the two factors
offset and leave things

SAS vs SATA: Same size, same speed, why SAS?
I''m building another 24-bay rackmount storage server, and I''m considering
what drives to put in the bays. My chassis is a Supermicro SC846A, so the
backplane supports SAS or SATA; my controllers are LSI3081E, again
supporting SAS or SATA.
Looking at drives, Seagate offers an enterprise (Constellation) 2TB 7200RPM
drive in both SAS and SATA configurations; the SAS model offers

Good SLOG devices?
Hi
I''m running OpenSolaris 148 on a few boxes, and newer boxes are getting installed as we speak. What would you suggest for a good SLOG device? It seems some new PCI-E-based ones are hitting the market, but will those require special drivers? Cost is obviously alsoo an issue here....

Thanks.

cannot replace X with Y: devices have different sector alignment
Well this is a new one....
Illumos/Openindiana let me add a device as a hot spare that evidently has a
different sector alignment than all of the other drives in the array.
So now I''m at the point that I /need/ a hot spare and it doesn''t look like
I have it.
And, worse, the other spares I have are all the same model as said hot
spare.
Is there anything I can do with this or

Performance drop during scrub?
Hi all
I have a test system with snv134 and 8x2TB drives in RAIDz2 and currently no Zil or L2ARC. I noticed the I/O speed to NFS shares on the testpool drops to something hardly usable while scrubbing the pool.
How can I address this? Will adding Zil or L2ARC help? Is it possible to tune down scrub''s priority somehow?
Best regards

Best 1.5TB drives for consumer RAID?
Which consumer-priced 1.5TB drives do people currently recommend?
I had zero read/write/checksum errors so far in 2 years with my trusty old Western Digital WD7500AAKS drives, but now I want to upgrade to a new set of drives that are big, reliable and cheap.
As of Jan 2010 it seems the price sweet spot is the 1.5TB drives.
As I had a lot of success with Western Digital drives I thought I would

client disconnects after one song is played
I'm using the latest CVS source under Linux using a playlist
of ogg files. When I use a client to connect on the same
machine, there is not any disconnect (xmms and zinf). When
using a client on a Windows machine, I get mixed results.
Zinf on windows will play thru the current song but then stops
when the song is finished and does not play the next song
being streamed (see log below).

Disk IDs and DD
Hiya,
Is there any reason (and anything to worry about) if disk target IDs don''t start at 0 (zero). For some reason mine are like this (3 controllers - 1 onboard and 2 PCIe);

0. c8t0d0 <ATA -ST9160314AS -SDM1 cyl 19454 alt 2 hd 255 sec 63>
/pci at 0,0/pci10de,cb84 at 5/disk at 0,0

Replacement disks for Sun X4500
I am bumping this thread because I too have the same question ... can I put modern 3TB disks (hitachi deskstars) into an old x4500 ?
If not, would the x4540 accept them ?

Undo/reverse zpool create
Hi,
If I add an entire disk to a new pool by doing "zpool create", is this reversible?
I.e. if there was data on that disk (e.g. it was the sole disk in a zpool in another system) can I get this back or is zpool create destructive?

out of HDD space - zfs degraded
Overnight I was running a zfs send | zfs receive (both within the same

and the system is degraded.

Hi there,
I?m using icecast 2.0.1 with darkice 0.14 streaming an 192kb mp3 stream.
Everything seems to work fine except that clients (eg winamp5) disconnect

Compatibility of Hitachi Deskstar 7K3000 HDS723030ALA640 with ZFS
Greetings,
Quick question:
I am about to acquire some disks for use with ZFS (currently using zfs-fuse
v0.7.0). I''m aware of some 4k alignment issues with Western Digital
advanced format disks.
As far as I can tell, the Hitachi Deskstar 7K3000 (HDS723030ALA640) uses
512B sectors and so I presume does not suffer from such issues (because it
doesn''t lie about the physical layout
