[Gluster-users] Regarding 2.0.4 booster

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

 

$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)

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? 

 

Appreciate your help. 

 

Thanks and regards,

Sudipto

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.

[Gluster-users] Regarding 2.0.4 booster

Hi, 

 

After modifying the booster.conf, I started getting the logs under
/tmp/booster.log but, I see the following error:

Can you please explain the above errors and what is that causing these
errors? 

 

Thanks and regards,

Hi Shehjar, 

 

The contents in booster.conf are in two separate lines. 

I will try out the test again by merging the contents of booster.conf
into one single line after I get my nodes back. 

 

Thanks and regards,

Sudipto

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.

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
