Hello, ?s there anyway to create raid6 or raid5 level glusterfs installation ? >From docs I undetstood that I can do raid1 base glusterfs installation or radi0 (strapting data too all servers ) and raid10 based solution but raid10 based solution is not cost effective because need too much server. Do you have a plan for keep one or two server as a parity for whole glusterfs system

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

We (a small college with about 3000 active accounts) are currently in the process of moving from UW IMAP running on linux to dovecot running on a cluster of 3 or 4 new faster Linux machines. (Initially using perdition to split the load.) As we are building and designing the system, I'm attempting to take (or find) benchmarks everywhere I can in order to make informed decisions and so

I would like to set up CentOS on 4 SATA hard drives that I would like to configure in RAID10. I read somewhere that Raid10 support is in the latest kernel, but I can't seem to get anaconda to let me create it. I only see raid 0, 1, 5, and 6. Even when I tried to set up raid5 or raid1, it would not let me put the /boot partition on it, and I though that this was now possible. Is it

Hi all I want to look at setting up a simple / cheap SAN / NAS server using normal PIV motherboard, 2GB (or even more) RAM, Core 2 Duo CPU (probably a Intel 6700 / 6750 / 6800) & some SATA HDD's (4 or 6x 320GB - 750GB). My budget is limited, so I can't afford a pre-built NAS device. Can this be done with CentOS? I've been looking FreeNAS (which is built on FreeBSD), and it

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

So when I couldn't get the raid10 to work, I decided to do raid5. Everything installed and looked good. I left it overnight to rebuild the array, and when I came in this morning, everything was frozen. Upon reboot, it said that 2 of the 4 devices for the raid5 array failed. Luckily, I didn't have any data on it, but how do I know that the same thing won't happen when I have

We have several DELL servers with MD1000 connect to it. Server will install CENTOS 5.x X86_64 version. My questions are: 1. Which configuration have better performance RAID5, RAID50 or RAID60? 2. how much performance difference? ___________________________________________________ ??????? ? ???????????????? http://messenger.yahoo.com.tw/

Hi What is the general state of btrfs RAID6 as of kernel 3.13-rc1 and the latest btrfs tools? More specifically: - Is it able to correct errors during scrubs? - Is it able to transparently handle disk failures without downtime? - Is it possible to convert btrfs RAID10 to RAID6 without recreating the fs? - Is it possible to add/remove drives to a RAID6 array? Regards, Hans-Kristian -- To

Hello everyone, I am currently running Dovecot as a high performance solution to a particular kind of problem. My userbase is small, but it murders email servers. The volume is moderate, but message retention requirements are stringent, to put it nicely. Many users receive a high volume of email traffic, but want to keep every message, and *search* them. This produces mail accounts up to

we have DELL 6800 server with 12 internal disks in it. O.S. is CENTOS 4.6 and SCSI control card is PERC 4e/di. We plan to configure 4 disks (5,8,9,10) as RAID5 or RAID50. This logical volume will be use as file systems and store database backup files. Can anyone tell me which one is better on performance? Thanks. ?????????Yahoo!??????2.0????????????? - ????? -------------- next part

Hi, we want to upgrade our infrastructure and are considering renting two different types of server by a provider: - A: one is with 80 GB SSD (and 12 GB memory) http://www.ovh.co.uk/products/eg_ssd.xml - B: the other with 750 GB SATA2 (and 8 GB memory). http://www.ovh.co.uk/products/eg_best_of.xml The target infrastructure will host: - a few public web sites (PHP / MySQL) - a development

Hiya, is there any recommendation out there to setup a btrfs FS on top of hardware or software raid5 or raid6 wrt stripe/stride alignment? From mkfs.btrfs, it doesn''t look like there''s much that can be adjusted that would help, and what I''m asking might not even make sense for btrfs but I thought I''d just ask.

Hello My company is changing server software to CentOS on Dell equipment. At the same time we are expanding our RAID system from standard SCSI to either SATA, or the technology brought forward by Coraid using the AoE protocol. Before we take the final decision I am looking for some real experience with Coraid products on a scale of 30+ disks. We will be using a cluster of four servers with a mix

Anyone having good results with 4-STABLE and the 3Ware 9000 series controllers? -- albert chin (china@thewrittenword.com)

So after troubleshooting this for about a week, I was finally able to create a raid 10 device by installing the system, copying the md modules onto a floppy, and loading the raid10 module during the install. Now the problem is that I can't get it to show up in anaconda. It detects the other arrays (raid0 and raid1) fine, but the raid10 array won't show up. Looking through the logs
