Comparison between the S-TEC Zeus and the Intel X25-E ??
I''m looking at the newly-orderable (via Sun) STEC Zeus SSDs, and they''re outrageously priced. http://www.stec-inc.com/product/zeusssd.php I just looked at the Intel X25-E series, and they look comparable in performance. At about 20% of the cost. http://www.intel.com/design/flash/nand/extreme/index.htm Can anyone enlighten me as to any possible difference between an STEC

WD caviar/mpt issues
I know that this has been well-discussed already, but it''s been a few months - WD caviars with mpt/mpt_sas generating lots of retryable read errors, spitting out lots of beloved " Log info 31080000 received for target" messages, and just generally not working right. (SM 836EL1 and 836TQ chassis - though I have several variations on theme depending on date of purchase: 836EL2s,

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 / backplane -- but we recently got one of the new SC847-based models with 24 disks up front and 12 in the

Disk failure chokes all the disks attached to the failing disk HBA
Dear All, It may be this not the correct mailing list, but I''m having a ZFS issue when a disk is failing. The system is a supermicro motherboard X8DTH-6F in a 4U chassis (SC847E1-R1400LPB) and an external SAS2 JBOD (SC847E16-RJBOD1). It makes a system with a total of 4 backplanes (2x SAS + 2x SAS2) each of them connected to a 4 different HBA (2x LSI 3081E-R (1068 chip) + 2x LSI

ZFS, SATA, LSI and stability
After having massive problems with a supermicro X7DBE box using AOC-SAT2-MV8 Marvell controllers and opensolaris snv79 (same as described here: http://sunsolve.sun.com/search/document.do?assetkey=1-66-233341-1) we just start over using new hardware and opensolaris 2008.05 upgraded to snv94. We used again a supermicro X7DBE but now with two LSI SAS3081E SAS controllers. And guess what? Now we get

disks in zpool gone at the same time
Hi, Yesterday I got all my disks in two zpool disconected. They are not real disks - LUNS from StorageTek 2530 array. What could that be - a failing LSI card or a mpt driver in 2009.06? After reboot got four disks in FAILED state - zpool clear fixed things with resilvering.

LVM and ZFS
I''m curious about if there are any potential problems with using LVM metadevices as ZFS zpool targets. I have a couple of situations where using a device directly by ZFS causes errors on the console about "Bus and lots of "stalled" I/O. But as soon as I wrap that device inside an LVM metadevice and then use it in the ZFS zpool things work perfectly fine and smoothly (no

kernel messages question
Hi I keep getting these messages on this one box. There are issues with at least one of the drives in it, but since there are some 80 drives in it, that''s not really an issue. I just want to know, if anyone knows, what this kernel message mean. Anyone?

Lost zpool after reboot
Hello, I have a dual boot with Windows 7 64 bit enterprise edition and Opensolaris build 134. This is on Sun Ultra 40 M1 workstation. Three hard drives, 2 in ZFS mirror, 1 is shared with Windows. Last 2 days I was working in Windows. I didn''t touch the hard drives in any way except I once opened Disk Management to figure out why a external USB hard drive is not being listed.

zfs hanging during reads
Hi, I hope there''s someone here who can possibly provide some assistance. I''ve had this read problem now for the past 2 months and just can''t get to the bottom of it. I have a home snv_111b server, with a zfs raid pool (4 x Samsung 750GB SATA drives). The motherboard is a ASUS M2N68-CM (4 SATA ports) with an Athlon LE1620 single core CPU and 4GB of RAM.

(Boot is an SSD connected to motherboard SATA.) This morning I got a cheerful email from my monitoring script: "Zchecker has discovered a problem on bigdawg." The full output is

7.1, mpt and slow writes
Hello, I think this needs a few more eyes: http://lists.freebsd.org/pipermail/freebsd-scsi/2009-January/003782.html In short, writes are slow, likely do to the write-cache being enabled on the controller. The sysctl used in 6.x to turn the cache off don't seem to be in 7.x. Thanks, Charles ___ Charles Sprickman NetEng/SysAdmin Bway.net - New York's Best Internet - www.bway.net

confusion and frustration with zpool
I have a zpool which has grown "organically". I had a 60Gb disk, I added a 120, I added a 500, I got a 750 and sliced it and mirrored the other pieces. The 60 and the 120 are internal PATA drives, the 500 and 750 are Maxtor OneTouch USB drives. The original system I created the 60+120+500 pool on was Solaris 10 update 3, patched to use ZFS sometime last fall (November I believe). In

For some reason mine are like this (3 controllers - 1 onboard and 2 PCIe); AVAILABLE DISK SELECTIONS: 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 1. c8t1d0 <ATA -ST9160314AS -SDM1

cryptic vdev name from fmdump

no hot spare activation?
While testing a zpool with a different storage adapter using my "blkdev" device, I did a test which made a disk unavailable -- all attempts to read from it report EIO. I expected my configuration (which is a 3 disk test, with 2 disks in a RAIDZ and a hot spare) to work where the hot spare would automatically be activated. But I''m finding that ZFS does not behave this way

zpool import hangs system
Hello, I''ve been using Nexentastore Community Edition with no issues now for a while now, however last week I was going to rebuild a different system so I started to copy all the data off that to my to a raidz2 volume on me CE system. This was going fine until I noticed that they copy was stalled, as well as the entire system was non-responsive. I let it sit for several hours with no
