Hi all I was working on my regular KDE session, when my system abruptly switched off because of a power failure. The next time i booted, i see kernel loaded ok but no further advance and a seemingly unfriendly line greets me "unconsistent file structure detected " . This repeated around 4-5 times when i tried rebooting. then i tried booting my windows which also failed( no surprises here although :)). Immediately on rebooting my linux kernel booted fine, recovered journal and there i go writing to you all from my Linux machine. I have FC5 installed with vanilla kernel 2.6.16. Can anybody send me links or hints on why this happened? And then why it recovered without any help? Strangely windows flashed me a prompt saying "cannot find some hal.system32 ( i am not sure but hal was there ) file" on the contrary the regular "ntoskrnl file missing error" :). An insight or pointers into how a filesystem recovers after a power loss would be appreciated and possible course which took place in my system .
