[root@Node2 ~]# /usr/sbin/oracleasm exit
Unmounting ASMlib driver filesystem: failed
Unable to unmount ASMlib driver filesystem

Solution Description
Check what is the process accessing the /dev/oracleasm using lsof command and kill the process id. Then try to execute oracleasm exit command.
lsof /dev/oracleasm

[root@xlaccd110 ~]# lsof /dev/oracleasm
COMMAND     PID   USER   FD   TYPE DEVICE SIZE/OFF                 NODE NAME
oracle_12  1222 oracle   11u   REG   0,36        0 18446612134580837288 /dev/oracleasm/iid/00000000000000A0

[root@xlaccd110 ~]# kill -9 1222
[root@Node2 /]# /usr/sbin/oracleasm exit
Unmounting ASMlib driver filesystem: /dev/oracleasm
Unloading module "oracleasm": oracleasm


Now you can try creating the asm disks using /usr/sbin/oracleasm createdisk command and then try the clusterware installation again.
