1. Add the settings to fstab then check the syntax

[19:07 root@server ~]# mount -a

2.reboot the os it will boot into read on file system dont panic

[18:43 root@server ~]# touch test
touch: cannot touch 'test': Read-only file system

3.check if the device has journaling if it is enabled that caused  read only file system while booting.

[18:50 root@server ~]# tune2fs -l /dev/sda3 | fgrep has_journal
Filesystem features: has_journal ext_attr resize_inode dir_index filetype needs_recovery extent 64bit flex_bg sparse_super large_file huge_file uninit_bg dir_nlink extra_isize

4.Making required changes

[18:55 root@server ~]# sudo tune2fs -o journal_data_writeback /dev/sda3
tune2fs 1.43.4 (31-Jan-2017)
[18:56 root@server ~]# tune2fs -O ^has_journal /dev/sda3

7.Check the disk write speeds with dd

[00:11 cipher ~/vagrant]$ sudo dd if=/dev/zero of=store6 bs=1M count=1000
1000+0 records in
1000+0 records out
1048576000 bytes (1.0 GB, 1000 MiB) copied, 3.06385 s, 342 MB/s
