Hi Shehjar,
Thanks for looking into this issue.
The file abc.txt is getting created; if you look at the C program; the
following line is basically printing out the file handle on stdout:
printf ("File handle %d\n",fh);
But, the booster log is getting generated.
Thanks and regards,
Sudipto

Hi,
I trying to run some tests w/booster client library and I had to
upgrade the glusterfs to version 2.0.4 from 2.0.2 (due to LD_PRELOAD
failures of the booster client library,
http://git.savannah.gnu.org/cgit/gluster.git/commit/?id=a3ece0caa52ad2ea
cf8a8691aaca53295cde972f).
Now, w/version 2.0.4 the LD_PRELOAD works OK, but the booster logs
are not generating and I am not sure whether booster is working or,
not.
I have the following booster.conf and client vol specification:
$cat /etc/glusterfs/booster.conf
/etc/glusterfs/glusterfs-client.vol /mnt/glusterfs glusterfs
subvolume=brick,logfile=/tmp/booster.log,loglevel=DEBUG
Please confirm whether the above content in booster.conf is on
a single line or two separate lines. It should all be on one line for
the logfile setting to be associated with /mnt/glusterfs.
$cat /etc/glusterfs/glusterfs-client.vol
volume brick
type protocol/client
option transport-type tcp/client # for TCP/IP transport
option remote-host 10.16.80.53 # IP address of the server
option remote-subvolume afr # name of the remote volume
end-volume
volume writebehind
type performance/write-behind
option window-size 1MB
subvolumes brick
end-volume
I have written a simple program to test few system calls and the
booster functionality:
int main() {
int fh;
char buffer[65];
fh = open("/mnt/glusterfs/abc.txt",O_WRONLY);
if (fh == -1) {
fh = creat("/mnt/glusterfs/abc.txt",O_WRONLY);
}
printf ("File handle %d\n",fh);
close(fh);
return 0;
}
When I run my program with LD_PRELOAD option, I get the following
message:
LD_PRELOAD="/usr/local/lib/glusterfs/glusterfs-booster.so"
/root/fstest/a.out
[2009-07-13 16:19:02] E
[libglusterfsclient.c:2447:glusterfs_glh_open] libglusterfsclient:
path lookup failed for (/abc.txt)
Is the above log message the only message that is being output? Were
there more lines that resembled this log line that you probably
removed for the purpose of this email?
Thanks
Shehjar
File handle 4
And there is no /tmp/booster.log created. The above log is only
observed while creating the file (in case abc.txt is not present).
Could you please advice on the booster config file and let me know
why I am not seeing any booster log?
I'll check why the booster log is not getting generated.
In the mean time, can you check if the file abc.txt really does not
get created on the backend?
If open is failing, it looks like the fd 4 is being returned by
creat call.

Appreciate your help.
Thanks and regards,
Sudipto
