Hi, On my x86_64 system I have a SiL311x controller that can do RAID. If I configure my 2 identical disks in a RAID1 setup, I would expect to see only 1 block device on Linux. Still I see 2 block devices. Is this intentional, and if so, isn't that dangerous ? (i.e. writing to both disks at the same time) Anyone with an insight, please explain :) -- dag wieers, dag at wieers.com,

Hi, according to http://www.freebsd.org/cgi/cvsweb.cgi/src/sys/dev/amr/amr.c?only_with_tag=RELENG_6 it seems MegaMGR for linux now can work. Any experience? -- Cris, member of G.U.F.I Italian FreeBSD User Group http://www.gufi.org/

Hi, I have a server (Dell PowerEdge SC1435, ServerWorks HT1000) on which I'd like to try installing FreeBSD. I've already failed to make 7.0 work on this box and was wondering if you have information about the behavior of the upcoming 7.1 on this hardware. I've been following the "HT1000 chipset errata saga" thread, and the commits by sos@ to CVS (around Jan 2008), but have

When I use SATA disks heavily on a 5.3-R machine (Athlon) with the SiI3512 disk controller, I get frequent (sometimes one every 1-5 minutes) WRITE_DMA timed out messages (with different blocks and both disks). It also panics with more than one kind of panic, and sometimes doesn't even get to finish the background fsck from the previous panic before dying again. Given that both disks get the

Dear List, This is my second post since I did not receive any answers the first time. I have P4P800-VM motherboard with serial ata controlers (ICH5) and serial ata discs. I managed to install FreeBSD 4.9-STABLE on this box when setting the IDE controller in legacy mode. Everything works normal except when booting, the drives are set into UDMA33 mode: atapci0: <Intel ICH5 SATA150

I have a new system which includes a Plextor PX-740a DVD+-R/RW CD-R/RW drive attached to an Asus A8V-MX motherboard. When I try to use burncd to burn a cd, it writes all of the data, says "fixating CD, please wait.." and then reports burncd: ioctl(CDRIOCFIXATE): Input/output error Oddly enough, the CD seems to be usable. I can successfully burn the same file if I use cdrecord. The

Hey folks, So what's the word on AHCI and bios drive geometry? I'm having a real pain of a time trying to get some 750gb sata drives running on my FreeBSD7 box in AHCI mode. It doesn't seem to matter what disk geometry I suggest to sysinstall, something complains of an invalid disk upon booting it. Actually, in AHCI mode the bios screen doesn't report any information on

I am having problems with silent data corruption on (some) drives connected to an MCP55 SATA controller. I have two servers, both running RELENG_7_0/amd64. One has the 570 Ultra chipset, the other has 570 SLI. Both chipsets have the MCP55 SATA controller. The server with 570 Ultra chipset has a bunch of older 250GB SATA-150 drives hooked up to the MCP55 controller and it is working just fine.

I want to import my zpool''s from FreeBSD 8.0 in OpenSolaris 2009.06. After reading the few posts (links below) I was able to find on the subject, it seems like it there is a differences between FreeBSD and Solaris. FreeBSD operates on directly on the disk and Solaris creates a partion and uses that... is that right? Is it impossible for OpenSolaris to use zpool''s from FreeBSD?

Hi All, Newbie here! I was wondering if anyone has succeeded in getting NCQ enabled with the ServerWorks chipset in the 2.6.18 kernel. I am running a Dell 1435/CentOS 5.0-x86_64 with dual 250GB Western Digital NCQ supported drives, when I load up the OS I get these messages: ata1: SATA link up 1.5 Gbps (SStatus 113 SControl 300) ata1.00: ATA-7, max UDMA/133, 488281250 sectors: LBA48

Does SATA Native Command Queueing and Linux software RAID1 play well together or is it better to turn off NCQ when doing software RAID?

Hi all, I'm sure this eventually will be resolved with a BIOS or kernel update, but in case someone experiences this on this or a similar motherboard, I thought I'd post a problem-and-workaround report.

I''ve been looking into the performance impact of NCQ. Here''s what i found out: http://blogs.sun.com/erickustarz/entry/ncq_performance_analysis Curiously, there''s not too much performance data on NCQ available via a google search ... enjoy, eric

Hi, I've installed CentOS5.2 on an INTEL Core 2 Duo (Intel(R) Core(TM)2 Duo CPU E6550 @ 2.33GHz), 4 GB RAM (MemTotal: 4072176 kB) and my system gets sevarel minutes to startup, specially on udev daemon. Once the system is UP, every command I run gets 100% CPU and every is very slowly at the point yum -y update never ends. The system installed by default this kernel 2.6.18-53.el5PAE.

Hi list I am running out of space on my notebook. So wanna buy additional and external storage. I don't wanna do a DIY-work, so searching for pre-built external hard disks. I wish to buy Seagate FreeAgent Pro [0]. Does it work under CentOS 5? Would you recommend me even better products? I am searching for good performance, noise-less, smart standard support and no useless features like
