Announcing the status of RAID-1 for Linux:
me and Ingo Molnar have done a new implementation of MD RAID-1. The software is still alpha quality, but expect a beta release soon. If you are interested in testing the code or you are doing something similar, then please get in touch with us.
Highlights:
- - RAID-1 over 2 or more devices. We are running an 8-ways mirrored test ext2fs filesystem with no crashes. Each of the 8 devices is mountable as an ext2 filesystem separately. Write speed scales very close to the theoretical 1/N rule.
- - no restriction on the device files. You can run a 2 ways mirrored RAID-1 over a local disk or over loopback devices.
- - read balancing (alpha quality): the reads are balanced over the devices, based on device usage statistics.
regards, Ingo Molnar (mingo@pc5829.hil.siemens.at) Miguel de Icaza (miguel@nuclecu.unam.mx)
