    [[email protected] appdata]# tune2fs -o dir_index,has_journal,uninit_bg /dev/sda7
    tune2fs 1.41.12 (17-May-2010)
    Invalid mount option set: dir_index,has_journal,uninit_bg
    [[email protected] appdata]# tune2fs -o extents,uninit_bg,dir_index /dev/sda5
    tune2fs 1.41.12 (17-May-2010)
    Invalid mount option set: extents,uninit_bg,dir_index

    I hit these both commands and it says invalid mount options set.

    I think it should be “Partitions instead of File Systems” in this line “Once you create file system using fdisk or parted command, use mke2fs command to create either of file system and make sure you replace hdXX with your device name.”

    how to change the filesystem path in linux /dev/db1 to /prod/db1

  6. Dragos Alexe says:

    A nice way is to manage LVM through ssm. Only one step-we can create a logical volume and volume group, choose file system type.
    ex: sudo ssm create -s 200GB -n disk0 –fstype ext4 -p my_volume /dev/sda /mount

    So we create a volume group named “my_volume”, create a 200GB LVM volume named disk0, after that format the volume ext4 file system, and mount it under “/mount” mounting point.
