Mount and fsck

Some commands useful for mounting (mount), unmounting (umount) and file checking (fsck).

1. Permanent mounts in

sudo nano /etc/fstab
#after editing check with (else reboot may fail):
mount -fav # = fake/all in fstab/verbose

2. if root partition is corrupt, use:

shutdown -rF now

3. for other partitions use

sudo service mysql stop; sudo service nginx stop; sudo service apache2 stop;
sudo service 4store stop; sudo service php5-fpm stop; sudo service fedora stop;
 sudo fuser -km /mnt/storage; sudo umount /mnt/storage; sudo fsck /dev/xvdb1
sudo fuser -km /mnt/dump; sudo umount /mnt/dump; sudo fsck /dev/xvdc1

4. Content of fstab as of 27.05.14

# /etc/fstab: static file system information.
# Use 'blkid' to print the universally unique identifier for a
# device; this may be used with UUID= as a more robust way to name devices
# that works even if disks are added and removed. See fstab(5).
