RAID @ home raid5  Installation

Is straightforward, You only have to follow the flow on screen. But here is a small HowTo:

RAID @ home raid5  HowTo: software RAID 5 install

What I want: software RAID 5, 4 disk of 320GB (real 305GB), using NVIDIA SATA chipset (not a dedicated RAID5 board).

Note: these pictures are not screenshots but picture taken with a sony camera…

http://www.openfiler.com/download
Download iso image from sourceforge and burn it to a CDInsert CD, and boot the PC
The first step is to TEST the quality of the medium.Openfiler did not recognize the NVIDIA controller.
choose "Add device"NVIDIA drivers (both Ethernet and drive controller) are at the end of the list.
I’ve add both drivers manually. Then "Done"The welcome page. click "Next"
Choose Keyboard language.I am not a novice, so let’s look at the advanced configuration.
The 4 disks are recognized. First I add some space for the Operating System.If You do not want to have a fifth disk just for the operating system, You’ll have to reserve a small amount of the global space for the Openfiler system. Note: this space will be located on the first disk and wont be in the raid array…so no redundancy.
Anyway it is uncommon to install the RAID engine on the RAID array itself.
Lets have 2GB for System.
And  1 GB for SWAPThen I click on th button RAID, since I have no RAID predefined only the first choice is available: "Create a RAID partition"
I will have to create a RAID partition for each of the 4 drives, I reserved 300GB for disk SDB300GB for disk SDC, for Disk SDA
and for disk SDD…till all 4 disks contains a RAID partition.I click on the RAID button for the 5th times: and choose "create a RAID device"
My disk array will be named /RAID (mount point), Raid level 5Result, a /RAID (device /dev/md0) with an EXT3 file system.
Nothing particular, default values are goodLanguage support: English
Choose TimeZoneEnter a good Root password. Mine s too small but it is only a prototype for determining performances and reliability of the setup.
Confirm all values entered by clicking Nextwait till the raid array initialization
CD get ejected, and reboot.Point your browser to https://box_ip:446/
And administer remotely the box

OpenFiler 1.12.0beta12.0beta2
  • The SATA controller was not recognized, this force me to use the 2.0Beta.
  • Unable to read or mount manually 2 different USB keys (FAT32), also unable to read CDROM (closed ISO and CDRW)
  • The network card (NFORCE 4 ) was not recognized by Openfiler 2.0Beta, I fail to copy the NVIDIA driver on the box because of point 2.
  • Is working perfectly, did not ask for any supplemental drivers

RAID @ home raid5  Conclusions

Why choosing itWhy avoiding it
Enterprise NAS features out of the boxYou do not need enterprise NAS features
Very nice WEB GUI4GB is too much and need an additional small disk only for starting the OS
A lot of functionalities
Limited choice of file system:

  • no Reiserfs, the swiss knife of all filesystem.
  • no JFS, XFS more adapted for big files
A big communities of users and developers, good online documentation.
No AMD64 version, but it’s really not an issue.
Very easy to have a software RAID5 arrays setup working.
Stable, Linux 2.6.9 kernel base.
GPL but an Enterprise version (with support) is also available.
