mpt_sas multipath problem?
Greetings, We''re trying out a new JBOD here. Multipath (mpxio) is not working, and we could use some feedback and/or troubleshooting advice. The OS is oi151a7, running on an existing server with a 54TB pool of internal drives. I believe the server hardware is not relevant to the JBOD issue, although the internal drives do appear to the OS with multipath device names (despite the fact

Experience with Promise Tech. arrays/jbod''s?
Greetings, In looking for inexpensive JBOD and/or RAID solutions to use with ZFS, I''ve run across the recent "VTrak" SAS/SATA systems from Promise Technologies, specifically their E-class and J-class series: E310f FC-connected RAID: http://www.promise.com/product/product_detail_eng.asp?product_id=175 E310s SAS-connected RAID:

Seagate Constellation vs. Hitachi Ultrastar
Happy Friday, List! I''m spec''ing out a Thumper-esque solution and having trouble finding my favorite Hitachi Ultrastar 2TB drives at a reasonable post-flood price. The Seagate Constellations seem pretty reasonable given the market circumstances but I don''t have any experience with them. Anybody using these in their ZFS systems and have you had good luck? Also, if

Sun 6120 array again
Greetings, Last April, in this discussion... http://www.opensolaris.org/jive/thread.jspa?messageID=143517 ...we never found out how (or if) the Sun 6120 (T4) array can be configured to ignore cache flush (sync-cache) requests from hosts. We''re about to reconfigure a 6120 here for use with ZFS (S10U4), and the evil tuneable zfs_nocacheflush is not going to serve us well (there is a ZFS

How to delegate filesystems from different pools to non-global zone
I''m trying to add filesystems from two different pools to a zone but can''t seem to find any mention of how to do this in the docs. I tried this but the second set overwrites the first one. add dataset set name=pool1/fs1 set name=pool2/fs2 end Is this possible or do I need to use different syntax? -Robert This message posted from opensolaris.org

SAN arrays with NVRAM cache : ZIL and zfs_nocacheflush
Hi, I read some articles on solarisinternals.com like "ZFS_Evil_Tuning_Guide" on http://www.solarisinternals.com/wiki/index.php/ZFS_Evil_Tuning_Guide . They clearly suggest to disable cache flush http://www.solarisinternals.com/wiki/index.php/ZFS_Evil_Tuning_Guide#FLUSH . It seems to be the only serious article on the net about this subject. Could someone here state on this

Un/Expected ZFS performance?
I''m running Postgresql (v8.1.10) on Solaris 10 (Sparc) from within a non-global zone. I originally had the database "storage" in the non-global zone (e.g. /var/local/pgsql/data on a UFS filesystem) and was getting performance of "X" (e.g. from a TPC-like application: http://www.tpc.org). I then wanted to try relocating the database storage from the zone (UFS

ZFS layout on hardware RAID-5?
Greetings, I followed closely the thread "ZFS and Storage", and other discussions about using ZFS on hardware RAID arrays, since we are deploying ZFS in a similar situation here. I''m sure I''m oversimplifying, but the consensus for general filesystem-type storage needs, as I''ve read it, tends toward doing ZFS RAID-Z (or RAID-Z2) on LUNS consisting of hardware

X4540 no next-gen product?
While I understand everything at Oracle is "top secret" these days. Does anyone have any insight into a next-gen X4500 / X4540? Does some other Oracle / Sun partner make a comparable system that is fully supported by Oracle / Sun? http://www.oracle.com/us/products/servers-storage/servers/previous-products/index.html What do X4500 / X4540 owners use if they''d like more

ZFS Performance Issue
This may not be a ZFS issue, so please bear with me! I have 4 internal drives that I have striped/mirrored with ZFS and have an application server which is reading/writing to hundreds of thousands of files on it, thousands of files @ a time. If 1 client uses the app server, the transaction (reading/writing to ~80 files) takes about 200 ms. If I have about 80 clients attempting it @ once, it can

zfs and backup applications
Hi, I was wondering if there have been any conversations with backup vendors like Veritas or EMC regarding better integration with ZFS. While I understand they can use the "native" mode of reading files from the filesystem, it would be great if there were agents that had options like making a snapshot and storing a "zfs backup" datastream that could be used for zfs restore.

patch enabling serial (tty) support
Folks, First, let me thank everyone involved for making QEMU available on the Solaris platform. It''s turning out to be really handy.... Here at work we''re required to use GroupWise calendaring (at least for the time being), and I''m trying to get a bit more organized, so thought I''d start (again) using a Palm handheld to take my calendar, etc. with me.
