I've tried to do an ls of <mountpoint>, <mountpoint>/a, <mountpoint>/a/b and
<mountpoint>/a/b/c while the dd was running in background and replace brick had
completed. I haven't seen any Input/Output error. However I've seen that 'ls'
sometimes takes more time than expected to complete. I'll try to see why.

The error logs you show seem to come from a different version of ec (program
lines do not match with current code). I've tried it with current master with
this patch added. What version are you trying ?
