[Gluster-users] Booster Problem

[Hassan Jafri]

I have a 2 node mirrored setup for gluster. I am trying to use booster for
my file I/O. For testing, I just tried writing a 1M file as follows:

node041 $ export GLUSTERFS_BOOSTER_FSTAB=/etc/glusterfs/booster.fstab
node041 $ LD_PRELOAD=/usr/lib64/glusterfs/glusterfs-booster.so  dd
if=/dev/zero of=/mnt/gscratch/file1M bs=1M count=1

I see the following in my booster.log file.  What am I doing wrong here

Also, in the glusterfsd.log, I see the following
