Last modified: 2015-01-04 18:00:57 EST
Is there a way how to find out open/closed files in cifs mount point (el6 have two separate columns for Posix Opens and Posix Mkdirs, el5 version seems to report both (files and dirs) to MkDirs column. el6 version: cat /proc/fs/cifs/Stats ...snipped... Opens: 0 Closes: 1 Deletes: 0 Posix Opens: 1 Posix Mkdirs: 0 ...snipped... el5 version: cat /proc/fs/cifs/Stats ...snipped... Opens: 0 Closes: 20Deletes: 10 <---- closed files Mkdirs: 21 Rmdirs: 1 <---- opened files ...snipped... ) +++ This bug was initially created as a clone of Bug #706333 +++ 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 Additional info: 2) \\linuxmachine\linuxshare SMBs: 865 Oplock Breaks: 0 Reads: 480 Bytes: 7847956 Writes: 184 Bytes: 10268672 Flushes: 0 Locks: 0 HardLinks: 0 Symlinks: 0 Opens: 0 Closes: 20Deletes: 10 <---- closed files Mkdirs: 21 Rmdirs: 1 <---- opened files <snip>
