similar to: RAID 5 vs. RAID 10

I'm setting up this huge RAID 6 box. I've always thought of hot spares, but I'm reading things that are comparing RAID 5 with a hot spare to RAID 6, implying that the latter doesn't need one. I *certainly* have enough drives to spare in this RAID box: 42 of 'em, so two questions: should I assign one or more hot spares, and, if so, how many? mark

Hello, In some weeks I'm going to reinstall some old RedHat9 based servers with Promise FastTrak TX2000 "semi-hardware" RAID1 controllers. I just tried to install CentOS 4.0 on a computer with a spare card and as usual both HDD attached to the RAID1 controller are seen separately by the installer because the specific driver for the TX2000 wasn't loaded. Nothing new here, it

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,

Dear gurus, Three DELL SC430s were purchased by my company a few months back and I've been told that when they spoke with the DELL representatives, they were informed that these servers were fully RHEL 4.0 compatible. Specs of the servers:- - Pentium 4 - 2.8 GHz - 1 GB RAM - 2x 250GB SATA HDDs I tried installing CentOS 4.0 on it but it doesn't seem to be able to detect any hard

Sorry for an OT post, but given the recent discussions here re raid, I was wondering if anyone had any info on the ITE 8212 RAID controller (GigaRAID) This is a PATA HW RAID as found on the GigaByte GA-8I915P-PRO motherboard. (I can see an IC on the board labeled GigaRAID. Their manual claims that is has it's own CPU). I am not using it because I have SATA, but I am still curious about

Hi, Would it be advisable to use SW-RAID using 2 different SATA controllers. My system happens to have both a VIA VT8237 and SIL3114 SATA controller, and I thought for both performance reason and redundancy using both for a 2 disk RAID1 array would be best. But it's possible that SW-RAID does not like or cannot overcome problems with such a setup or that one of these drivers is known to

Has anyone created or rebuilt a Linux Software RAID having mirrored partitions on unequal sized hard disks ? There is a CentOS 5 server having two 400 GB hard disks with five mirrored partitions (software RAID 1) and one of the hard disks is dying. Since new 400 GB HDDs are not available here, we are exploring the possibility of replacing the faulty hard disk with one of a higher capacity (500 GB

Arch = x86_64 CentOS-6.4 We have a cold server with 32Gb RAM and 8 x 3TB SATA drives mounted in hotswap cells. The intended purpose of this system is as an ERP application and DBMS host. The ERP application will likely eventually have web access but at the moment only dedicated client applications can connect to it. I am researching how to best set this system up for use as a production host

Hello all..... I would like to know if anyone here has had good experience with this Supermicro motherboard.....http://supermicro.com/products/motherboard/P4/E7221/P8SCT.cfm I am thinking about using it in an entry level mail and file server with a 3ware card and 200 GB SATA drives. Cost is a factor here otherwise I would go for an Opteron board instead. JC

hi, I am planning to replace my old CentOS 6 mail server soon. Most details are quite obvious and do not need to be changed, but the old system was running on spinning discs and this is certainly not the best option for todays mail servers. With spinning discs, HW-RAID6 was the way to go to increase reliability and speed. Today, I get the feeling, that traditional RAID is not the best option for

Hi All Just like to know if some one got or has running a "VIA 6410 IDE RAID Controller" with centos 4(.1) I have a server I need to get install, that has this on-board I have even test the with Knoppix 3.8 and it don't not pick it up at all. but the card and the drivers work ok ( tested this with the bart PE (XP) cd ) See BUG.

My future plan currently looks like this for my VPS hosting solution, so any feedback would be appreciated: Each Node: Dell R210 Intel X3430 Quad Core 8GB RAM Intel PT 1Gbps Server Dual Port NIC using linux "bonding" Small pair of HDDs for OS (Probably in RAID1) Each node will run about 10 - 15 customer guests Storage Server: Some Intel Quad Core Chip 2GB RAM (Maybe more?)

Hi, I've used mdadm for years now to manage software raids. The task of using fdisk to first create partitions on a spare drive sitting on a shelf (raid 0 were my 1st of 2 drives failed) is kind of bugging me now. After using fdisk to create the same partition layout on the new drive as is on the existing drive and then using mdadm to finish every thing up is a little tedious. Any

Hi, I've been playing with CentOS quite a bit lately (and I must say it's growing on me!! :) and I was now able to convince my boss that we could get a box and gradually start migrating our hosting from win2k3 to centos. So anyway, I've got a new box at the colo ready up and running - P4 3Ghz w/HT 2Ghz RAM 2x70Gb HDD, running Centos4.4 fully up-to-date. Now my two questions are;

Hi everyone, I'm looking into setting up a SATA hardware raid, probably 5 to use with CentOS 4. I chose hardware raid over software mostly because I like the fact that the raid is transparent to the OS. Does anyone know of any SATA controllers that are well tested for this sort of usage? From what I can tell from googling, this is more or less where RHEL stands: Red Hat Enterprise Linux

Hello, I was wondering if someone could help me, I'm putting together a Server for personal use, I want to virtualize a few servers(mail, web, ssh) and use it as a NAS, but I have a question if I can use Multiple RAID Arrays using the following HW: Intel Xeon Quad Core X3430 ASUS P7F-M LGA 1156 - LSI MegaRAID(integrated) - HighPoint RocketRAID 2640x1 2 Hitachi 500GB HDDs 4 Hitachi 1TB HDDs

How can I tell wich HDD to swap, when the "cat /proc/mdstat" says one HDD of the RAID1 array has died? Does the HDD's has some serial numbers, that I can see in "reality", and I can get that number from e.g.: a commands output? How could I know wich HDD to swap in e.g.: a RAID1 array? thank you -------------- next part -------------- An HTML attachment
