On CentOS release 6.7, there's file system problem.
Aftert reboot /home is set under /home (/home/home) like followings.
# ls -l /home
total 48

I have set on fstab /home with 'mount bind' but it seems like bind is
not
effective.
/etc/fstab is following.
# cat /etc/fstab

By default, nothing mounts "bind" filesystems. The init scripts don't read the hole fstab file, there are filters to mount only some filesystems types. If you want to mount the "bind" FS on boot, you need to add the related commands into /etc/rc.d/rc.local. Sylvain. Pensez ENVIRONNEMENT : n'imprimer que si ncessaire
Thank you Sylvain. I want try to use /etc/rc.d/rc.local. Are there any document about writing into /etc/rc.d/rc.local?

I'm also running CentOS 6.7 and have several bind-mounts in my /etc/fstab: /var/home /home none bind 0 0 /var/lib/libvirt/etc /etc/libvirt none bind 0 0 /srv/news /var/spool/news none bind 0 0 All of them occur automatically when the system boots. The "mount -a" in /etc/rc.d/rc.sysinit takes care of them just fine. The filter on that command is _excluding_ certain types. Note that the first two letters are "no", which applies to all the listed types: mount -a -n -t nonfs,nfs4,smbfs,ncpfs,cifs,gfs,gfs2i,glusterfs -O no_netdev [rkn] ~ $ df Filesystem 1K-blocks Used Available Use% Mounted on /dev/mapper/vg_omega3g-rootvol 11963960 5995348 5337828 53% / tmpfs 8194160 340 8193820 1% /dev/shm /dev/sda1 689128 130200 508752 21% /boot /dev/mapper/vg_omega3g-var 38166008 8282340 27921892 23% /var /dev/mapper/vg_omega3g-srvlv 564310312 360619492 175002488 68% /srv /dev/mapper/vg_omega3g-virt 194274580 119917252 64617656 65% /var/lib/libvirt tmpfs 2097152 652 2096500 1% /tmp [rkn] ~ $ df /home /etc/libvirt /var/spool/news Filesystem 1K-blocks Used Available Use% Mounted on /var/home 38166008 8282340 27921892 23% /home /var/lib/libvirt/etc 194274580 119917252 64617656 65% /etc/libvirt /srv/news 564310312 360619508 175002472 68% /var/spool/news -- Bob Nichols "NOSPAM" is really part of my email address.
