Description Branislav Náter 2011-05-20 06:56:36 UTC 
Description of problem:
cifsiostat doesn't report files opened on share mounted from
linux machine. cifsiostat obtains values from /proc/fs/cifs/Stats. When file on
linux share is opened, this action is counted as "Mkdirs" in
/proc/fs/cifs/Stats.


Version-Release number of selected component (if applicable):
sysstat-7.0.2-6.el5

How reproducible:
always

Steps to Reproduce:
1. mount samba share from linux machine
2. open /proc/fs/cifs/Stats
3. run "touch file.txt" on share mounted in step 1.
  
Actual results:
Mkdirs and Closes values are increment by one:

Opens: 0 Closes: 1Deletes: 0
Mkdirs: 1 Rmdirs: 0

Expected results:
Opens and Closes values are increment by one:

Opens: 1 Closes: 1Deletes: 0
Mkdirs: 0 Rmdirs: 0

Comment 1 Ivana Varekova 2011-06-08 12:47:49 UTC 
This bug can be fixed without the changes in kernel api in /proc/fs/cifs/Stats
files - there is kernel bug for it (706339) which blocks this one.

ops "can be"-> "can't be"
