[Gluster-devel] [Gluster-users] heal hanging

Hi, 

As mentioned glusterfs.get_real_filename getxattr is called when we need to 
check if a file(case insensitive) exists in a directory. 

You could run the following command to get to know the perf details. 
I guess you need to have debuginfo installed for this to work. 

Record perf: 
$perf record -a -g -p <PID of process to instrument> -o perf-glusterfsd.data 

Generate the stat: 
perf report -g -i perf-glusterfsd.data 

Attaching perf might slow down the process further, hence recommended to use it in test setup. 

Regards, 
Poornima
