Ran, Can you please elaborate on - "2 servers in distrebute mod , each has 1 TB brick that replicate to each other using DRBD" Also, how many drives do you have and what does iowait look like when you write a big file ? Tell us more about the configs of your servers, share the volume files.

For example time dd if=/dev/zero of=file bs=10240 count=1000000 OR mv 20gig_file.img into gluster mount . When that happen the all storage freezes for the entire proccess , mails , few vps's , simple dir etc.. Our setup is quite simple at this point , 2 servers in distrebute mod , each has 1 TB brick that replicate to each other using DRBD . iv monitored closly everting on this big writes and noticed that its not mem , proc , network problem . Iv also checked the same setup with simple NFS and its not happening there . Anyone has any idea on how to fix this , if you cant write big files into gluster without making the storage unfunctional then you cant realy do anything . Please advise , _______________________________________________ Gluster-users mailing list Gluster-users at gluster.org http://gluster.org/cgi-bin/mailman/listinfo/gluster-users
