I know, but in linux it's still a lot better than Windows, which I today regret I ever introduced it in... Don't get me wrong, reliability is fine, but the recheck on every restart is kinda' bothersome and takes like forever Today I have five 500GB-disks raided on linux machine. Remove one for parity and I have 2TB of real space available. Doing a 0+1, ie 1TB, would indeed be better as performance goes, but 1TB of space, well, it just isn't enough unfortunately. As it is now, the 2TB shebang is mounted as /backup. Does that count as a single filesystem? -- /Sorin -------------- next part -------------- A non-text attachment was scrubbed...
