This site is the Linux-raid kernel list community managed reference for Linux software RAID as implemented in recent 2.6 kernels. It should replace many of the unmaintained and out-of-date documents 'out there' such as the Software RAID HOWTO and the Linux RAID FAQ.
Where possible, information should be tagged with the minimum kernel/software version required to use the feature. Some of the information on these pages are unfortunately quite old, but we are in the process of updating the info (aren't we always...)
Linux raid issues are discussed in the linux-raid mailing list to be found at http://vger.kernel.org/vger-lists.html#linux-raid
Currently working on site issues
We were hit by spam a while back and closed down account creation. We are looking into solutions for the spam, account, hosting, and where OSDL will take us. We hope to have it working soon. In the meantime, please check back later or email below.
There is an Overview section that is based on the RAID HowTo, covering the following:
- Why RAID?
- Hardware issues
- RAID setup
- Detecting, querying and testing
- Tweaking, tuning and troubleshooting
- Related tools
- Partitioning RAID / LVM on RAID
The document is sprinkled with references to the deprecated raidtools which are being gradually removed.
