dedicated ZIL/L2ARC
We are looking into the possibility of adding a dedicated ZIL and/or L2ARC devices to our pool. We are looking into getting 4 ? 32GB Intel X25-E SSD drives. Would this be a good solution to slow write speeds? We are currently sharing out different slices of the pool to windows servers using comstar and fibrechannel. We are currently getting around 300MB/sec performance with 70-100% disk busy.

Best way to measure performance of ZIL
Hi all,
I currently have a OCZ Vertex 4 SSD as a ZIL device and am well aware of
their exaggerated claims of sustained performance. I was thinking about
getting a DRAM based ZIL accelerator such as Christopher George''s DDRDive,
one of the STEC products, etc. Of course the key question i''m trying to
answer is: is the price premium worth it?

tdb idmap returns different GID's for the same SID from time to time
Greetings!
I have a samba 3.6.18 acts as a domain member.
I'm using a samba nss and creating local groups for a domain users.
Here part of my nsswitch.conf:

The problem is that the tdb unix GID mappings returns different ID from time to time for the same SIDs.

ZFS for ISCSI ntfs backing store.
I''m looking to move our file storage from Windows to Opensolaris/zfs. The windows box will be connected through 10g for iscsi to the storage. The windows box will continue to serve the windows clients and will be hosting approximately 4TB of data.
The physical box is a sunfire x4240, single AMD 2435 processor, 16G ram, LSI 3801E HBA, ixgbe 10g card.

ZIL SSD performance testing... -IOzone works great, others not so great
Hi folks,
I would appreciate it if someone can help me understand some weird
results I''m seeing with trying to do performance testing with an SSD
offloaded ZIL.
I''m attempting to improve my infrastructure''s burstable write capacity
(ZFS based WebDav servers), and naturally I''m looking at implementing
SSD based ZIL devices.

ZFS ZIL + L2ARC SSD Setup
I have some questions about the choice of SSDs to use for ZIL and L2ARC.
I''m trying to build an OpenSolaris iSCSI SAN out of a whitebox system,
which is intended to be used as a backup SAN during storage migration,
so it''s built on a tight budget.
The system currently has 4GB RAM, 3GHz Core2-Quad and 8x 500GB WD REII

Hardware RAID vs. ZFS RAID
Hello,
I have a Dell 2950 with a Perc 5/i, two 300GB 15K SAS drives in a RAID0 array. I am considering going to ZFS and I would like to get some feedback about which situation would yield the highest performance: using the Perc 5/i to provide a hardware RAID0 that is presented as a single volume to OpenSolaris, or using the drives separately and creating the RAID0 with OpenSolaris and ZFS?

ZFS with Equallogic storage
I''m planning on setting up an NFS server for our ESXi hosts and plan on using a virtualized Solaris or Nexenta host to serve ZFS over NFS.
The storage I have available is provided by Equallogic boxes over 10Gbe iSCSI.
I am trying to figure out the best way to provide both performance and resiliency given the Equallogic provides the redundancy.

SCSI write retry errors on ZIL SSD drives...
I posted a thread on this once long ago[1] -- but we''re still fighting
with this problem and I wanted to throw it out here again.
All of our hardware is from Silicon Mechanics (SuperMicro chassis and
motherboards).
Up until now, all of the hardware has had a single 24-disk expander /

rsync errors
Ah... there's your answer. ssh is working fine, as you say, but you're invoking rsync without telling it to user ssh, so it's using rsh. If you've got this, you don't need rsyncd.conf. The syntax you're using tells rsync to use an external transport.
rsync -e ssh file rmt_host:/tmp

L2ARC and ZIL on same SSD?
Are there any drawbacks to partition a SSD in two parts and use L2ARC on one partition, and ZIL on the other? Any thoughts?

zfs raidz1 and traditional raid 5 perfomrance comparision
Hi,
for zfs raidz1, I know for random io, iops of a raidz1 vdev eqaul to one physical disk iops, since raidz1 is like raid5 , so is raid5 has same performance like raidz1? ie. random iops equal to one physical disk''s ipos.
Regards
