DBFS_MOUNT starts but not shown in `df -h`

When I start DBFS resource, it starts:

[root@primrac1 /]# crsctl start resource dbfs_mount

CRS-2672: Attempting to start 'dbfs_mount' on 'primrac2'

CRS-2672: Attempting to start 'dbfs_mount' on 'primrac1'

CRS-2676: Start of 'dbfs_mount' on 'primrac2' succeeded

CRS-2676: Start of 'dbfs_mount' on 'primrac1' succeeded

But if I check using `df -h` I can't see the mount point.

If I try to cd to that mount point I get error:

[root@primrac1 /]# cd /dbfs

-bash: cd: /dbfs: Input/output error

If I stop mount point:

[root@primrac1 /]# crsctl stop resource dbfs_mount

CRS-2673: Attempting to stop 'dbfs_mount' on 'primrac1'
