Submission + - Open source NAS Clustering
dago writes: I've been searching for a solution to make a "network raid" out of different NAS and storage servers, each with 2-4 HDD. In particular, I'm looking at a way to aggregate that space in a RAID5 way, to have a large, redundant space for backup and archiving. Access would be via SMB/CIFS or FTP and performance doesn't really matter.
I've already tried solutions like Lustre or GlusterFS, but they doesn't seem to provide directly "RAID5 over TCP/IP", just stripping, mirroring or both (RAID 0, 1, 1+0). On the commercial side, "scale out NAS" products usually requires to buy new, specific hardware and aims at very large installations.
Did anybody already aggregated NAS storage using open source components ? How ?
