Hello: fsck saved me from re-installing the whole OS today!(Ubuntu jaunty) The things I wonder tho, is that; 1- is there a way to run fsck without answering every question? Can it really fix all errors? If so How please? 2- Is it really a bad idea to run it while the system is "mounted" , fully up and running (Including the GUI)? If so how can one bring the OS into the safer mode? (how can you unmount it and still run commands)?! Thanks A Lot! PS: That reminds me of another question but I guess I make a new thread for it. (question about re-installing OS without losing everything? Is it possible?) Regards; Now if you like to know the details read on.. well, I am running Ubuntu 9.04 on my workstation and run xdm as GUI I was doing something in the terminal when I started to have problems. I think I ran the rsync the other day and accidentally copied over some files from an older version of Ub. to my machine. I should have used the --dry-run switch with rsync but didnt! Anyway I was trying to chroot to a directory when I started getting error msgs! Then I used pico (nano) to edit/save a file when I got the msg saying Cannot save, Read Only OS!? Would not save my file, so I rebooted when I did I got that infamous "Coltrol D" msg! (and I hate that msg, cuz I can never log in as root and cannot fix anything) lol except today I got lucky and got in with my password then the fsck worked. In fact I am using the same machine right now! Any way I hope my Christian friends are not offended by the title lol ;-) As Jesus saves good people the fsck saves Linux machines! Thank You!
