How can I check and mark bad blocks on Linux startup? There are a number of options available and most of them require accessing hardware and running live CD's. But I would like to avoid and perform everything using command line without going to the server room and talking to admins who have the keys.

I have ArchLinux with / on ext4fs.

If your init scripts support it, you can add -c -c to /fsckoptions (then create /forcefsck and reboot). Unfortunately, this feature isn't available everywhere. You probably have to reboot to a LiveCD/LiveUSB instead.

  • On Arch you still can force fsck check with kernel parameters fsck.mode=force. May be related: unix.stackexchange.com/questions/106892/… Commented Sep 1, 2014 at 15:46
  • yes, i've forced fsck using manual from ArchLinux. Next challenge is to run badblocks, but seems that i have to go to server room and use LiveCD. Thanks for your help! Commented Sep 2, 2014 at 13:21
  • Not sure if that works, but you could go into single user mode, remount / readonly, and then run badblocks. Commented Sep 2, 2014 at 17:08
