[Samba] I/O error samba mount point (only with smbfs)

[Iranna D Ankad]

Hi,
I am getting an I/O error while running fsstress on client samba mount point
(only with smbfs)

Can anyone, please look into this problem?

Problem Description:
x370 was configured for samba server & x206f as samba client. 
fsstress was running from two samba mount points from client i.e /SAMBA1 (type
cifs) & /SAMBA2 (type smbfs). 

There was no load generating on /SAMBA2 & hence was not populating /SAMBA2  
server mount point.But the load is properly getting generated on /SAMBA1 both 
client & server mount points. 

 
Steps to reproduce:- 
Samba server configuration: (giving just brief idea) 
create two partitions using fdsik of size 4 GB & make filesystem ext2 & ext3 
respectively. Mount these 2 partitions with directories /SAMBA1 & /SAMBA2 
created in / and then give 777 permissions to /SAMBA1 & /SAMBA2. 
Then start smb & nmb daemons 
  
Samba client configuration: 
create directories /SAMBA1 & /SAMBA2 in / & give them 777 permissions.Then 
 
mount -t cifs -o username=root //<samba-server ip-address>/SAMBA1  /SAMBA1 
mount -t smbfs -o username=root //<samba-server ip-address>/SAMBA2  /SAMBA2 
 
Run fsstress which is present in LTP test suite 
(i.e /ltp-full../testcase/kernel/fs/fsstress) 
 
nohup ./fsstress -d /SAMBA1 -l 0 -n 1000 -p 2 -r & 
nohup ./fsstress -d /SAMBA2 -l 0 -n 1000 -p 2 -r & 
 
Additional information:- 
 
The nohup.out from client shows: 
 
seed = 1130028113 
seed = 1129370642 
p0: Input/output error 
p1: Input/output error 
rm: cannot remove `/SAMBA2/*': Input/output error

configuration in order to reproduce this problem.
