I think it is exact the same size like before after you nulled it, because it is maybe cached by the appl. or something like that. Seems it accepts the writing 1st, but a file handle appears to be still open on that file that revokes the former action somehow. I am no programmer, maybe someone else can explain it in detail.

Expand FS means increasing the size of the mount?
Yes, if that's an option for you. The appl. might crash, spit errors or something like that if it runs out of space anyway.
Quote:
I cannot both rely on removing the file or expanding the file. The only solution I can go for is a safe cleanup of this file, without removing or renaming.
You misunderstood me. When you are allowed to get a short downtime maybe once a week, depending on how fast the log is growing, or once per night, whatever, you stop the application graceful, cp that file to a.log.`date %+w` for example, compress it and just null the original like you tried already "> a.log". When your log files are set, start your appl. again.
Write a little script for this and put it as a cronjob - done.

NAME
page_util_quote - page character quoting utilities
SYNOPSIS
package require page::util::quote ?0.1?
package require snit
::page::util::quote::unquote char
::page::util::quote::quote'tcl char
::page::util::quote::quote'tclstr char
::page::util::quote::quote'tclcom char
_________________________________________________________________
DESCRIPTION
This package provides a few utility commands to convert characters into various forms.
API
::page::util::quote::unquote char
A character, as stored in an abstract syntax tree by a PEG processor (See the packages grammar::peg::interpreter, grammar::me, and
their relations), i.e. in some quoted form, is converted into the equivalent Tcl character. The character is returned as the result
of the command.
::page::util::quote::quote'tcl char
This command takes a Tcl character (internal representation) and converts it into a string which is accepted by the Tcl parser, will
regenerate the character in question and is 7bit ASCII. The string is returned as the result of this command.
::page::util::quote::quote'tclstr char
This command takes a Tcl character (internal representation) and converts it into a string which is accepted by the Tcl parser and
will generate a human readable representation of the character in question. The string is returned as the result of this command.
The string does not use any unprintable characters. It may use backslash-quoting. High UTF characters are quoted to avoid problems
with the still prevalent ascii terminals. It is assumed that the string will be used in a double-quoted environment.
::page::util::quote::quote'tclcom char
This command takes a Tcl character (internal representation) and converts it into a string which is accepted by the Tcl parser when
used within a Tcl comment. The string is returned as the result of this command.
