Helllo
Uptime of 5days, and this ext3 crashes. I know that at reboot itll be funny. testdisk and photorec eventually.
Man, ext3 is fragile, is you dont do tunefs -c and reboot time to time.
So how can I get an huge uptime, not worried, cuz this guy will be able to fix itself while running?

is that possible?
No. At some point physical failures will not be auto-repairable -- unless your HDD is like the VW Beetle in the Woody Allen film. The nearest you can get is hot-swappable storage and some human intervention to replaced failed/failing devices.

so how can servers Linux and BSD runs, with huge uptime ?
I dont believe, they can autofix, or use fuse, ... or dont know
well, here freeshell.org
so they daily restart their machine server?
Smartctl checks the physical integrity of the drive, it doesn't do anything with the fs inside of it. So it really doesn't help with the topic at hand.

Raids, redundancy, hot swappable hardware.
but how does google with their billions of GB, they shall certainly check their drives. How does servers?
Probably with a combination of raids and clusters, I guess. Google has *lots* of machines, certainly turning one of them off will have zero impact on the services that Google can offer.
