Hello all, I've been on a real roller coaster ride getting a large virtual host up and running. One troublesome thing I've discovered (the hard way) is that the drivers for Marvell SAS/SATA chips still have a few problems. After Googling around quite a bit, I see a significant number of others have had similar issues, especially evident in the Ubuntu forums but also for a few

Hello, Having a problem with software RAID that is driving me crazy. Here's the details: 1. CentOS 6.2 x86_64 install from the minimal iso (via pxeboot). 2. Reasonably good PC hardware (i.e. not budget, but not server grade either) with a pair of 1TB Western Digital SATA3 Drives. 3. Drives are plugged into the SATA3 ports on the mainboard (both drives and cables say they can do 6Gb/s). 4.

Hello folks, I am experiencing a weird problem at bootup with large RAID-6 arrays. After Googling around (a lot) I find that others are having the same issues with CentOS/RHEL/Ubuntu/whatever. In my case it's Scientific Linux-6 which should behave the same way as CentOS-6. I had the same problem with the RHEL-6 evaluation version. I'm posting this question to the SL mailing list

Hi, I have a SATA PCIe 6Gbps 4 port controller card made by Startech. The kernel (Linux viz1 2.6.32-220.4.1.el6.x86_64) sees it as Marvell Technology Group Ltd. 88SE9123 I use it to provide extra SATA ports to a raid system. The HD's are all "WD2003FYYS" and so run at 3Gbps on the 6Gbps controller. However I am seeing lots of instances of errors like this

Hello list members, My adventure into udev rules has taken an interesting turn. I did discover a stupid error in the way I was attempting to assign static disk device names on CentOS-5.5, so that's out of the way. But in the process of exploring, I installed a trial copy of RHEL-6 on the new machine to see if anything had changed (since I intend this box to run CentOS-6 anyway). Lots

Hi list, I googled around but couldn''t find anything on whether someone has good or bad experiences with the Caviar *Blue* drives? I saw in the archives Caviar Blacks are *not* recommended for ZFS arrays (excluding apparently RE3 and RE4?). Specifically I''m looking to buy Western Digital Caviar Blue WD10EALS 1TB drives [1]. Does anyone have any experience with these drives? If

Hi, I have a new server HP proliant DL320 G4, with two 160 GB SATA hdds.. I have installed CentOS 4.5 with mdadm without any problem, but when I disconnect one disk the server does not boot or I received a kernel panic when booting... I have disabled the SATA embeded raid (BIOS) and nothing.. I've also download the driver from HP site HP (Embedded SATA RAID Controller Driver Diskette for Red

Good day. Thanks in advance for any help. I have a Tyan S2895 (Thunder K8WE) with 2 275 Opterons and the latest (1.02) bios. It appears to have an nVidia nForce SATA chipset which connects to a 250gb WD Caviar SATA drive. Using the CentOS 4 update 2 x86_64 DVD, the install is peachy until half-way through the "performing post install configuration" bit. Then it hangs forever. I

Hello list members, In CentOS-5.5 I'm trying to achieve static assignment of SCSI device names for a bunch of RAID-60 drives on a Supermicro motherboard. The "scsi_id" command identifies all drives ok. The board has one SATA controller and three SAS/SATA controllers ... standard on-board ICH-10 ATA channels, an on-board LSI SAS/SATA controller, and two add-on SAS/SATA

Does anyone know of a card that actually works with CentOS 4 that supports Raid10? I don't think CentOS support software raid 10 from the installer.

A customer is looking to replace or augment their Sun Thumper with a ZFS appliance like 7320. However, the Thumper was used not only as a protocol storage server (home dirs, files, backups over NFS/CIFS/Rsync), but also as a general-purpose server with unpredictably-big-data programs running directly on it (such as corporate databases, Alfresco for intellectual document storage, etc.) in order to

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,

Dear R developers, (Apologies about previous incomplete e-mail, I fat-fingered a keyboard shortcut)?? I recently upgraded to 3.2.3 and am getting mystifying errors with my in-development code (available at https://github.com/gertvv/gemtc/tree/feature/regression).

I believe I've posted before about one of the speed issues we were having, of backups taking many, many hours that should *not* take that long. My manager and I finally nailed it down to the h/d itself. Identical boxes, and he tried a backup of one system which took under two hours, while the same regular one rand nearly six. I'd been googling on and off for weeks, and this morning, ran

Dear all, I am trying to repeat an example from Sokal and Rohlfs "Biometry" -- Box 11.4, example of a randomized-complete-blocks experiment. The data is fairly simple: series genotype weight 1 pp 0.958 1 pb 0.985 1 bb 0.925 2 pp 0.971 2 pb 1.051 2 bb 0.952 3 pp 0.927 3 pb 0.891 3 bb 0.892 4
