Hi All,
I have an NFS server using the Solaris package version
11.11,REV=2009.11.11, and an NFS client of version 1:1.2.0-4ubuntu4.1
(Ubuntu 10.04LTS).
I use the following Makefile to start (using the command 'make -j')
muliple gunzip processes to unzip the gz files (each gz file is of
several GBs, the decompressed files are about 2 times of the original
files).
I wait for make to run a while so that all the gunzip processes start.
White the process are running, I try to type ctrl-C to kill the make
processes, but it doesn't kill it. Then I use the command 'kill' to
kill make. However, the gnuzip processes are not killed automatically.
I have to use 'kill -9' to kill all gunzip processes. But the
directory txtfiles is not accessible anymore.
Has anybody seen a similar problem when kill processes accessing NFS?
Is there a way to fix this issue by tuning configurations of NFS
client or server?
$ cat Makefile
.PHONY: all
INFILES:=$(wildcard gzfiles/*.txt.gz)
OUTFILES:=$(patsubst gzfiles/%.txt.gz,txtfiles/%.txt,$(INFILES))
all: $(OUTFILES)
$(OUTFILES): txtfiles/%.txt: gzfiles/%.txt.gz
mkdir -p $(dir $@); gunzip -c $< > $@
clean:
$(RM) -rf txtfiles
$ ll gzfiles/*
