[RFE] Striping should have optional parity/checksum
Last modified: 2016-02-17 19:19:45 EST
Description of problem:
Striping currently behaves only like RAID-0. It would be great if there could be an option to have a parity brick. The idea is to behave more like RAID-5 (or possibly RAID-6), which would tolerate the failure of 1 or more bricks. This enhancement would allow increased data integrity and increased usable storage as compared to current options (like replica 2).
Hello Dynamic Packet...
Please have a look at http://www.gluster.org/community/documentation/index.php/Planning34/Disperse
We will keep the current stripe translator as is, and will come up with new translator to handle the request you asked for.
This is included in glusterfs-3.6 as disperse aka ec (erasure coding).
