Mount a fs using autofs with fail-over

I have 2 source IPs and common mount /SAP_01, mount the file system from 1st source IP if not available mount with 2nd IP and vise versa (kind of fail-over). I create a script to check which IP is active #!/bin/bash primary="//192.168.10.200/SAP_01" secondary="//10.25.9.200/SAP_01" mount_point="/SAP_01" cifs_port=445 log_file="/var/log/cifs_events" log_event() { echo "$(date '+%Y-%m-%d %H:%M:%S') - $1" >> $log_file } # Check if the mount point is stale if mountpoint -q $mount_point && ! nc -z -w 1 192.168.10.200 $cifs_port && ! nc -z -w 1 10.25.9.200 $cifs_port; then log_event "Mount point is stale. Forcing unmount." umount -l $mount_point fi # Check if the primary server is available if nc -z -w 1 192.168.10.200 $cifs_port; then log_event "Primary server is available. Mounting $primary." echo "$primary" else log_event "Primary server is down. Checking secondary server." if nc -z -w 1 10.25.9.200 $cifs_port; then log_event "Secondary server is available. Mounting $secondary." echo "$secondary" else log_event "Neither CIFS server is available." echo "Neither CIFS server is available" >&2 exit 1 fi fi its working fine , it will give UNC patch **//192.168.10.200/SAP_01** or **//10.25.9.200/SAP_01** but I am not able to mount this via autofs I added /etc/auto.master /- /etc/auto.cifs and /etc/auto.cifs /SAP_01 -fstype=cifs,rw,uid=30000,gid=4010,file_mode=0777,dir_mode=0777,_netdev,credentials=/etc/cifs_credentials :/usr/local/bin/cifs_failover.sh But while running autofs I am getting error mount_mount: mount(generic): calling mkdir_path /SAP_01 mount_mount: mount(generic): calling mount -t cifs -o rw,uid=30000,gid=4010,file_mode=0777,dir_mode=0777,_netdev,credentials=/etc/cifs_credentials /usr/local/bin/cifs_failover.sh /SAP_01 >> mount.cifs: bad UNC (/usr/local/bin/cifs_failover.sh) mount(generic): failed to mount /usr/local/bin/cifs_failover.sh (type cifs) on /SAP_01 dev_ioctl_send_fail: token = 370 Any solution to fix this ? I just want to fail-over if primary source unavailable and vise-versa. Please help me to resolve this issue. I just want to fail-over if primary source unavailable and vise-versa.
