For example: UUID=c6e22f63-e63c-40ed-bf9b-bb4a10f2db66 /mnt ext4 errors=remount-ro 0 2 After this change has been made, see the command examples below to finish forcing fsck to run.Instructions.

But when you have an initramfs, you can run the fsck from there, before mounting the filesystem. At that point there's no reason to mount it first ro, and then remount it rw./dev/sda1: UNEXPECTED INCONSISTENCY; RUN fsck MANUALLY. (i.e., without -a or -p options) fsck exited with status code 4. The root filesystem on /dev/sda1 requires a manual fsck. BusyBox v1.27.2 (Ubuntu 1:1.27.2-2ubuntu3.2) built-in shell (ash) Enter 'help' for a list of built-in commands. (initramfs)The root filesystem is marked as corrupted and there are actually some errors. I would like to fix these errors, but I can't. I tried several things (shutdown -rF now, touch /forcefsck, set FSCKFIX=yes in /etc/default/rcS, tune2fs -c 1 -C 1 /myfilesystem): no check is done. To see the filesystem mounted on / (root), run the df command with -h: To configure file system check on n number of reboots, run the following: tune2fs -c 1 /dev/sda5 - (file system check will run after each reboot before the loading the OS). or alternatively. tune2fs -c 10 /dev/sda5 - will set fsck to run after 10 reboots. The filesystem is corrupted by the above full fsck run to a state where fsck will no longer be able to handle and fix. Solution Before making any changes to the filesystem using full fsck (that is, before answering "yes" to any questions prompted by full fsck), run "fsck -F vxfs -n" (Solaris version) or "fsck -t vxfs -n" (Linux version) on the ...sudo btrfs filesystem resize amount /mount-point. The amount can be a set size, such as "+3g" for an increase in 3 GiB, or it can be "max" to grow the file system to fill the whole block device. Use "-3g" for a decrease of 3 GiB. Consider example below to add new partition /dev/sda4 to /home and extend it.Filesystem can be either a device's name (e.g. /dev/sda) or its mount point. fsck run with no options will check all devices in /etc/fstab. It might be neccesary to run fsck from single-user mode Note: You need to be "root" to use any of the below mentioned command * Take system down to runlevel one:/dev/sda1: UNEXPECTED INCONSISTENCY; RUN fsck MANUALLY.
