Yes, after you have deleted the file there is little you can do to recover the allocated space apart from killing and restarting the process(es) that have the file open.
As RudiC points out you are better off writing zero size to the logfile eg:
Code:
# truncate -s0 /var/log/httpd/access_log
Or
Code:
# :> /var/log/httpd/access_log
As a long-term solution you should consider using the logrotate daemon to keep your logfile sizes down.

MERGELOGS(1) General Commands Manual MERGELOGS(1)NAME
mergelogs - merge and consolidate web server logs
SYNOPSIS
mergelogs -p penlog [-c] [-d] [-j jitter] [-t seconds] server1:logfile1 [server2:logfile2 ...]
EXAMPLES
mergelogs -p pen.log 10.0.0.1:access_log.1 10.0.0.2:access_log.2
mergelogs -p pen.log 10.0.18.6:access_log-10.0.18.6 10.0.18.8:access_log-10.0.18.8
DESCRIPTION
When pen is used to load balance web servers, the web server log file lists all accesses as coming from the host running pen. This makes it
more difficult to analyze the log file.
To solve this, pen creates its own log file, which contains the real client address, the time of the access, the target server address and
the first few bytes of the requests.
Mergelogs reads pen's log file and the log files of all load balanced web servers, compares each entry and creates a combined log file that
looks as if the web server cluster were a single physical server. Client addresses are replaced with the real client addresses.
In the event that no matching client address can be found in the pen log, the server address is used instead. This should never happen, and
is meant as a debugging tool. A large number of these indicates that the server system date needs to be set, or that the jitter value is
too small.
You probably don't want to use this program. Penlog is a much more elegant and functional solution.
OPTIONS -c Do not cache pen log entries. The use of this option is not recommended, as it will make mergelogs search the entire pen log for
every line in the web server logs.
-d Debugging (repeat for more).
-p penlog
Log file from pen.
-j jitter
Jitter in seconds (default 600). This is the maximum variation in time stamps in the pen and web server log files. A smaller value
will result in a smaller pen log cache and faster processing, at the risk of missed entries.
-t seconds
The difference in seconds between the time on the pen server and UTC. For example, this is 7200 (two hours) in Finland.
server:logfile
Web server address and name of log file.
