Checking the line where you define $size, we see your variable $fs, being part of the list $filesystems.

The problem is, that the "for" doesn't get the values of $filesystems as single elements - it takes them as one. And there is no filesystem called "/export /home/ts".

So add the line
Code:
IFS=" "

to help for/do/done to parse the value of $filesystems as single values.

Example:
Code:
root@isau02:/etc/apt> filesystems="/export /home/t2/"
root@isau02:/etc/apt> for bla in ${filesystems}; do echo ${bla}; done
/export /home/t2/                                        # it takes it as a single value, ignoring the blank
root@isau02:/etc/apt> IFS=" "
root@isau02:/etc/apt> for bla in $filesystems; do echo $bla; done
/export
/home/t2/

You can debug your shell scripts easily by echoing variables in between and use options like "set -x" or "set -xv".

virtual-filesystems

virtual-filesystems(7)					 Miscellaneous Information Manual				    virtual-filesystems(7)

NAME

       virtual-filesystems - event signalling that virtual filesystems have been mounted

SYNOPSIS

       virtual-filesystems [ENV]...

DESCRIPTION

       The  virtual-filesystems  event	is  generated  by  the mountall(8) daemon after it has mounted all virtual filesystems listed in fstab(5).
       mountall(8) emits this event as an informational signal, services and tasks started or stopped by this event will do so	in  parallel  with
       other activity.

       This event is typically used by services that must be started in order to mount other filesystems.  When this event occurs, common filesys-
       tems such as /usr may not be mounted.  For most normal services the filesystem(7) event is sufficient.

EXAMPLE

       A service that wishes to be running once virtual filesystems are mounted might use:

	      start on virtual-filesystems

SEE ALSO

       mounting(7) mounted(7) local-filesystems(7) remote-filesystems(7) all-swaps(7) filesystem(7)
