Down here we have Africa power. |
25 |
Africa power makes post-Katrina power look tame. |

|
27 |
Total corruptions in 5 years with reiserfs-3.6 and NO ups in that environment |
28 |
= zero. |

I can't fairly comment on ext[234] as I don't have the same length of |
31 |
experience with them. From what other commentators have said elsewhere it |
32 |
looks like with optimum settings and tweaks they can be just as good as I got |
33 |
from reiser, but that's just hearsay from me. |
34 |
|
35 |
My gut feel on this is that any modern fs will be built to be able to tolerate |
36 |
blackouts - it's almost a requirement these days. So it's likely a 6 and half- |
37 |
dozen question in reality. Except XFS as you know, but that's a special case |
38 |
(aggressive caching virtually requires a UPS or guaranteed no-downtime power) |
