On CentOS7 df shows not correct data about /dev/vdb
# df
Filesystem 1K-blocks Used Available Use% Mounted on
/dev/mapper/centos-root 13105152 2695388 10409764 21% /

With /etc/fstab I set as following.
UUID=f3b3a4ae-757f-4c68-bbbe-c05ded3d8580 /mnt/extradiskA ext4
defaults,usrquota,grpquota 1 2
/dev/mapper/centos-swap swap swap defaults 0 0
/mnt/extradiskA/home /home none bind 0 0
/mnt/extradiskA/log /var/log none bind 0 0
/mnt/extradiskA/mysql /var/lib/mysql none bind 0 0
/mnt/extradiskA/.backup /.backup none bind 0 0
/mnt/extradiskA/.daily_backup /.daily_backup none bind 0 0
So, df must show like following.
/dev/vdb 515928320 xxxxx xxxxxx xx% /mnt/extradiskA
Please tell me how I can fix this problem.
Tadao
