Since the built in kernel doesn't have the raid10 module for some reason, I would like to custom compile a kernel that does, and install with it. How would I go about doing this? Russ

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

We have a RHEL2 server that has had one of the drives in the raid array fail. I would like to do a full backup of the system before we replace the raided drive, in case the second drive decides to die during the procedure. What is the recommended way to back up a linux system? I was thinking of doing a snapshot, but the system is ext3 with no LVM. It has been suggested to hook up a usb

I had a raid5 on an onboard Intel ICH9R chip under windows. Windows crashed, as it often does, and the array became degraded. At some point during the rebuild, I was doing some hardware maintanence and unplugged one of the drives, and forgot to plug it back in. When I booted up, the array came back as failed. I turned off the PC, plugged the drive back in and powered it back on, but the

We are building an exchange cluster with two front end Outlook Web Access servers. We would like to at least have some sort of failover, and prefereably load balancing for them. The MS recommended way is to use NLB, but for various reasons that's not working with our set up. We are looking to set up a single linux server and use something like LVS to load balance/fail over the

I just downloaded solaris. They have two versions, the split DVD that comes with two 1.2GB zipped chunks and an exe which is 1.2GB but uncompresses to the full 2.5+GB. I found some info on them here: http://www.nosltd.com/nosso.html Any idea how they achieve such great compression? Looks like they're using a proprietary algorithm and don't offer any downloads. Also looks like

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

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Are there any repositories for CentOS 5.5 that keep the latest MySQL versions? After enabling everything I can think off (CentOS, rpmforge, epel), I'm still only seeing 5.0.77-4.el5_5.4. 5.5 came out yesterday and 5.1 has been around for a while.

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/

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

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.

We have an application that was build on a windows platform that expects a case insensitive file system. Is there a way to set one up in CentOS? NTFS should work, I think, but I feel uneasy using that under Linux. Russ

Hi all, Sorry for the OT. I've got an IBM N3300-A10 NAS. It runs Data Ontap 7.2.5.1. The problem is, from the docs it says that it only supports either RAID-DP or RAID4. What I want to achieve is Max Storage Capacity, so I change it from RAID-DP to RAID4, but with RAID4, the maximum disk in a RAID Group decrease from 14 to 7. In the end, either using RAID-DP or RAID4, the capacity is the same.

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.

I am researching how to best set this system up for use as a production host

Hey folks, CentOS / PostgreSQL shop over here.
