If you show us your script and the output it produces, we might or might not be able to help you do what you're trying to do. If you don't show us what you're doing, there is very little chance that we can guess what you're doing wrong (or if what you're trying to do is possible), since it seems that these mount points were not automounted.

We also need to see the output from showmount -a for a subset of the mount points you're trying to unmount. (Please be sure that the portion of the showmount output you show us matches the output you show us from your script.)

showmount

showmount(8)						      System Manager's Manual						      showmount(8)

NAME

       showmount - Shows remote NFS compatible mounts on a host

SYNOPSIS

       showmount [-adeT] [-t nnn] [host]

FLAGS

       Lists  all mount points in the form: hostname:dirpath. In this form, hostname is the name of a client that has remotely mounted a directory
       from an NFS server, and dirpath is the directory that has been mounted.	Lists only directories that have been remotely mounted by clients.
       Shows  host's  exports  list.  Specifies an infinite timeout.  The default timeout value is 25 seconds.	Specifies a timeout value, in sec-
       onds.  The default timeout value is 25 seconds.

       The default value for host is the current hostname.

DESCRIPTION

       The showmount command shows status information about the NFS server on host. By default, it prints the names of all  hosts  that  have  NFS
       file  systems  mounted  from  the  server  host.   See  NFS: Network File System Protocol Specification, RFC1094, Appendix A for a detailed
       description of the protocol.

NOTES

       The mountd daemon running on the server only has an idea of the actual mounts, since the NFS server is stateless. showmount will only  dis-
       play the information as accurately as the mount daemon reports it.

       The default timeout value of 25 seconds can be too brief to read and verify an export list.  If you receive timeout messages when using the
       showmount -e command, use either the -T or the -t options to increase the timeout value.

FILES

       Specifies the command path Contains a table of local file systems mounted by remote NFS clients
