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 -------------- next part -------------- An HTML attachment was scrubbed...
