Description Sayalee 2018-12-07 11:03:21 UTC 
Description of problem:
When rebalance operation is in progress (in this case, due to remove brick operation), performing an rm -rf from mount point leaves few directories undeleted with 'ENOTEMPTY' error

Version-Release number of selected component (if applicable):
3.12.2-31

How reproducible:
1/1

Steps to Reproduce:
1. create a dist-rep (4x2) volume
2. run linux untar operation frm fuse mount
3. run remove-brick to remove 2x2 bricks from gluster server and rm -rf * from the mount
4. rm -rf on few directories failed with 'ENOTEMPTY'

[root@dhcp41-226 vol3]# cd dir2
[root@dhcp41-226 dir2]# rm -rf *
rm: cannot remove ‘linux-4.6.4/arch/arm’: Directory not empty
[root@dhcp41-226 dir2]# rm -rf *
rm: cannot remove ‘linux-4.6.4/arch’: Directory not empty
[root@dhcp41-226 dir2]# rm -rf *
rm: cannot remove ‘linux-4.6.4/arch/frv/include/asm’: Directory not empty
[root@dhcp41-226 dir2]# rm -rf *
rm: cannot remove ‘linux-4.6.4/arch’: Directory not empty
[root@dhcp41-226 dir2]# rm -rf *
rm: cannot remove ‘linux-4.6.4/arch/mips/include/asm’: Directory not empty

Actual results:
rm -rf failed with 'Directory not empty'

Expected results:
ENOTEMPTY error should not be seen
