Hi I've 6 x 3TB SATA drives available with a view to consolidating long term storage to a single raid array intended to be operational more or less 24/7. I've done this a few times too many and run into the inevitable issues like waiting days to expand raid arrays whilst running the risk of disk failure in a rebuild, inability to detect bit rot etc. so I'd like to "future proof" as far as is economically plausible.
I'm thinking btrfs as file system configured as raid6, yielding 12TB useable storage, protecting against two simultaneous disk failures. Rebuilds and/or expanding the array should be pretty quick given only actual data blocks are written on rebuild or expansion as opposed to traditional raid systems that write out the entire array. Before I go down this road I'd appreciate thoughts/ suggestions/ alternatives? Have I left anything out? Most importantly is btrfs raid6 now stable enough to use in this fashion? -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
