[arch-general] Segmentation fault and (possibly) file system bug while removing gnome-extra
Hi, All. For several reasons I decided to remove the group 'gnome-extra' from my system. During the uninstallation, something went wrong. For a 'funny' reason, which I may explain later, I wasn't able to post the error log in the form of text here, so I will upload a photo as an attachment[1] with this mail... So, I switched to a getty and started the uninstallation. No errors occourred until it reached the 15th package. The package name was 'telepathy-idle'. All of a sudden the system printed a large section of dmesg, saying something like it had run into a kernel bug(?). The pacman was then killed, leaving the zsh reporting a segmentation fault... I felt the possibility that I wasn't able to handle this problem on my own, so I took a photograph using my mobile without even thinking, which proved to be useful later. Then I ran # dmesg >> /root/dmesg.output hoping to save the error log. I tried to restart the uninstallation, but the pacman freezed. Even pressing CTRL-C didn't work. I switched to another getty attemptting to terminal in, but after I entered 'root' and pressed ENTER, no any output. The course was just left there, blinking. Having no choice, I reboot the system using the magic sysrq keys... Rebooted, I checked the package changes. Confusingly, no packages was removed, even the previous should-be-removed 15 ones! Bad feeling about this, I checked the /root directory, and here came the most confusing part: The dmesg.output file was GONE! It seemed that all the data that should have been written to the disk were discarded... (And that's the reason why I have to post the error log in the form of shooted image... Somehow, I found myself a potential prophet... :P JUST KID...) Judged by this, together with the previous error log, I would say it's a file system bug... But, confused, how can an uninstallation of packages end up like this way? :( I would appreciate any help from you guys. Truly would. Thank you in advance! :) PS: I'm not going to post my pacman.conf here because all modification I had ever done to this file was to enable the color output. I suppose it can be excluded from the possible causes... And if necessary, I would recur the uninstallation with '--debug' flag enabled and report it to the upstream developer...

Hello again, All. Update: I ran fsck in archiso this morning, and found sth interesting. To sum up, fsck.f2fs exit with signal 11, arguing segmentation fault. Just the same as the error I faced last night. (I wrote the previous mail last night and sent it this morning.) Now that I knew it's DEFINITELY a file system error. And I wonder if there's any solution except formatting the whole partition. Again, I shooted the error log and I'll post it here: http://imgsrc.baidu.com/forum/pic/item/2318034c510fd9f90c88e96d2f2dd42a 2934a47c.jpg Lots of thx!!!

uhm, I'd suggest you to write proper link
Well... It seems that all the links were divided into two lines... But after putting them in one line accordingly, it should be proper links... Sorry. :P ------------------ Regards, Robert S.
