In Linux, when you import a filesystem in "fstab" you need to define the FSCK option. This option checks if filesystems last fsck time is more than certain days ago. In this case, the system performs an fsck operation. And on this step If it fails you need to connect system from over Console or connect the serial port to apply fsck manually. Fsck operation can take a few minutes or hours which depends on your filesystem size.
If you need to fast boot I recommend disabling FSCK on boot.
There are a few ways to disable FSCK on boot.
You can change fstab; In fstab file, last column refers to the FSCK option. For root filesystem it should be "1" for the other "2". If you want to disable FSCK just change it to "0"
# cat /etc/fstab |grep svn /dev/mapper/vgroot-LogVol02 /svn ext4 defaults 0 0
You can use tune2fs to change filesystem parameters.
# tune2fs -l /dev/vgroot/LogVol02 | egrep -i 'mount count|check' Mount count: 5 Maximum mount count: 21 Last checked: Tue Nov 3 12:52:13 2015 Check interval: 15552000 (6 months)
First, you need to change these parameters;
- Setting maximal mount count to "-1"
- Setting interval between checks to "0" seconds.
Apply new settings with this command;
#tune2fs -c 0 -i 0 -l /dev/vgroot/LogVol02 | egrep -i 'mount count|check' Setting maximal mount count to -1 Setting interval between checks to 0 seconds Mount count: 5 Maximum mount count: -1 Last checked: Tue Nov 3 12:52:13 2015 Check interval: 0 (<none>)
Reboot system with "-f" option. But don't forget this is not permanently action. It 'll only perform boot without FSCK for this boot time. If your server crashed or rebooted without "-f" option it 'll perform FSCK if it's defined on your configuration.
#shutdown -rf now
