Volume type:
Disperse Volume 8+2 = 1080 bricks
First time added 8+2 * 3 sets and it started giving issue in listing
folder. so, remounted mount point and it was working fine.
Second added 8+2 *13 sets and it also had the same issue.
when listing folder it was returning an empty folder or not showing all the
folders.
when ongoing write was interrupted it throws an error destination not
folder not available.
adding few more lines from log.. let me know if you need full log file.
