I have a Raid5 software partitioned using LVM (at centos 5.2 installation).Actually the raid is composed by 3 320Gb HDD.I would like to replace them with 3 2T hdd, but I'm worried ... [by Kirys]
I'm running an IntelRST-based RAID5 of 3x WD20EZRX (Green 2TB) which has now reached FULL.
I'm looking to Upgrade/Replace with 3x WD30EFRX (Green 3TB), occupying the same MB-based SATA2 Ports (all others are occupied).
I have a Current Full Backup on an External Drive.
So, the question becomes:
Should I perform an Upgrade-in-Place (migrating the Data by Deprecating Replacing and then Rebuil
I currently have openSuse 11.0 installed on a software dmraid raid5 volume. Today I tried to install openSuse 11.2 instead, but I got stuck in the partitioning. I have a /home partition which is also a software dmraid raid5 volume and I want this partition to be left untouched.
I've been searching for hours and giving up / to scared to delete all my data. I have a file server running CentOS 6.5 which has 4 WD RED 2TB drives (all > 1 year old) in software raid 5 with mdadm, and some other drives (not important). I used LVM on top of the RAID5 for easy management and partitioned the volume group as ext4.
All of this worked really good until I needed to reboot.
Has anyone tried installing FC 18 or 19 (new Anaconda) on an existing RAID 5 system (I have installed Debian in software RAID5 as md0). Fedora 17 installs RAID 5 as md1 without a hitch (/boot on seperate partition of course). If you have let lime know the steps you took using the new Anaconda. Otherwise I'm just upgrading to o19 beta from 18 which was a FC 17 upgrade (using Fedora.
in 2007 I'd tried to use the onboard RAID (only with AMD's boards) and was disappointed... at least I used Win-software-RAID instead.
Now I'd like to setup 5 similar "lowcost" streamserver with at least 5TB space
- anybody experience with chipsets improvements?
- which would be the best for RAID5?
- any benchmarks available RAID5?
- RAID5 vs. RAID10?
