hail, I write just to make sure its dead. I've lost the first disk on a ZFS pool (jbod). Now I can't mount it with only the second disk. The first disk clicks to death :( [root@optimus ~]# zpool status pool: pool state: UNAVAIL status: One or more devices could not be opened. There are insufficient replicas for the pool to continue functioning. action: Attach the missing

So after toying around with some stuff a few months back I got bogged down and set this project aside for a while. Time to revisit. <BR><BR> Looking around there still is not a good "these cards/motherboards" work list. the HCL is hardly ever updated, and its far more geared towards business use than hobbyist/home use. So bearing all of that in mind I will need the

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. I am using it

Setup: Osol.11 build 109 Athlon64 3400+ Aopen AK-86L mobo adeptec 1250sa Sata PCI controller card [re-posted from accidental post to osol `general'' group] I''m having trouble with an adaptec 1205sa (non-raid) SATA PCI card. It was all working fine when I plugged 2 used sata 200gb disks of a windows xp machine into it. Booted my osol server and added a zpool mirror using those

Hi all; We have a Solaris 10 U9 x86 instance running on Silicon Mechanics / SuperMicro hardware. Occasionally under high load (ZFS scrub for example), the box becomes non-responsive (it continues to respond to ping but nothing else works -- not even the local console). Our only solution is to hard reset after which everything comes up normally. Logs are showing the following: Jan 8

Is anyone having issues with these particular cards (especially the newer SATAII variant) and the stock CentOS kernels? Are they well supported enough such that a "yum update" suffices to keep them synced up with patches without having to hand edit the kernel or build special modules from 3Ware each time? Cheers,

Has anyone on the list used one of these w/Linux? We currently use Linux + Cinelerra for editing uncompressed video (and a few dual G5 macs running Final Cut Pro). Current editing stations are getting a bit long in the tooth so I've been mulling over a mass upgrade. 8-) These cards are interesting to me because they are PCI-X and support 4 SATAII drives per multilane/infiniband

Dear all, I'm trying to setup a development server which hosts a number of virtual hosts.and i need your advice with the following: 1.

Hi people, I am building a cheap remote rsync backup server using a software raid 5 array of 4 500GB disks. What I have available on the market is: 1. HITACHI GST Deskstar T7K500 500GB 7200rpm 16MB cache Serial ATA II-300 2. SEAGATE Barracuda 7200.10 with NCQ 500GB 7200rpm 16MB cache Serial ATA II-300 3.

Hi all, some results from my configuration. I''ve this configuration (I''m not interested in raw top performances but in reliability.. so, I can accept slow MB/sec and prefer to rely on a RAID6, for example): 1 Infortrend iSCSI Array A16E-G2130-4 with: - 1GB DDR cache - RAID6 - 7 x 500GB sataII Seagate ST3500630NS with 16mb (no budget for SAS) - one of the logic volumes (about

I was recently evaluating much the same question but with out only a single pool and sizing my disks equally. I only need about 500GB of usable space and so I was considering the value of 4x 250GB SATA Drives versus 5x 160GB SATA drives. I had intended to use an AMS 5 disk in 3 5.25" bay hot-swap backplane. http://www.american-media.com/product/backplane/sata300/sata300.html I priced

Hi all :) I''ve been wanting to make the switch from XFS over RAID5 to ZFS/RAIDZ2 for some time now, ever since I read about ZFS the first time. Absolutely amazing beast! I''ve built my own little hobby server at home and have a boatload of disks in different sizes that I''ve been using together to build a RAID5 array on Linux using mdadm in two layers; first layer is

Hello list. I'm new here, and I'm joining because I'm having a problem wich I can't figure out the solution myself. Here's what's happening: A Samba 3.0.24 is serving files to seven Windows XP clients. Three of those clients run an application with a BDE database. The problem is that when running this application on Samba, it gets very, VERY slow, causing it to hang. I

Hey folks, CentOS / PostgreSQL shop over here. I'm hitting 3 of my favorite lists with this, so here's hoping that the BCC trick is the right way to do it :-) We've just discovered thanks to a new Munin plugin http://blogs.amd.co.at/robe/2008/12/graphing-linux-disk-io-statistics-with-munin.html that our production DB is completely maxing out in I/O for about a 3 hour stretch from

Hello, I''m quite interested in ZFS, like everybody else I suppose, and am about to install FBSD with ZFS. On that note, i have a different first question to start with. I personally am a Linux fanboy, and would love to see/use ZFS on linux. I assume that I can use those ZFS disks later with any os that can work/recognizes ZFS correct? e.g. I can install/setup ZFS in FBSD, and later use

1. I have a 4x18GB drive setup as RAIDZ. Now when thinking about it in terms of RAID5 I would expect to get (4-1)x18 worth of drive space, but DF -h shows 4x18. Is this a bug or do I not understand? 2. Once again thinking in RAID5 terms if I have 4X18GB and 12X9GB drives and I want to make a RAIDZ of all of them I would expect the 18GB to be treated at 9GB so the RAIDZ would be 16X9GB. Is

So, I took four 1.5TB drives and made RAIDZ, RAIDZ1 and RAIDZ2 pools. The sizes for the pools were 5.3TB, 4.0TB, and 2.67TB respectively. The man page for RAIDZ states that "The raidz vdev type is an alias for raidz1." So why was there a difference between the sizes for RAIDZ and RAIDZ1? Shouldn''t the size be the same for "zpool create raidz ..." and "zpool
