http://bugzilla.opensuse.org/show_bug.cgi?id=908068 Bug ID: 908068 Summary: fuser -m not handling block devices properly Classification: openSUSE Product: openSUSE Distribution Version: 13.2 Hardware: x86-64 OS: openSUSE 13.2 Status: NEW Severity: Minor Priority: P5 - None Component: Basesystem Assignee: bnc-team-screening@forge.provo.novell.com Reporter: Greg.Freemyer@gmail.com QA Contact: qa-bugs@suse.de Found By: --- Blocker: --- Per my understanding of fuser, if /dev/sdb1 is mounted on /mnt, then both "fuser -m /mnt" and "fuser -m /dev/sdb1" should give the same output. This interpretation of the fuser command line is corroborated by an upstream bug related to the functionality and the fact it was fixed for psmisc v22.20 http://sourceforge.net/p/psmisc/bugs/53/ Apparently there is a regression in v22.21: Neither the unpatched psmisc v22.21 source nor the patched version in the openSUSE 13.2 release function that way, but they don't function like each other either. The unpatched source creates a fuser binary that complains /dev/sdb1 is not a mount point: # with vanilla upstream source
fuser -m /dev/sdb1 Specified filename /dev/sdb1 is not a mountpoint.
That is literally true, but the man page for fuser says a block device can be passed as a value for the -m argument and the mounted filesystem will in turn be queried. Thus the vanilla source from upstream has a bug. I have added a comment to <http://sourceforge.net/p/psmisc/bugs/53/> that it should be re-opened. == If testing the fuser binary provided with openSUSE 13.2 a different wrong result is provided: # with openSUSE patched source
fuser -m /dev/sdb1 /dev/sdb1: 1150rce 1152rce 1206rce 1207rce 1209rce 1312rce 1353rce 1355rce 1358rce 1363rce 1376rce 1377rce 1379rce 1385rce 1387rce 1391rce 1394rce 1402rce 1409rce 1411rce 1448rce 1461rce 1469rce 1470rce 1475rce 1512rce 1631rce 1635rce 1644rce 1658rce 1661rce 1664rce 1665rce 1680rce 1685rce 1728rce 1781rce 1791rce 1801rce 1807rce 1810rce 1811rce 1815rce 1835rce 1839rce 1897rce 2355rce 2378rce 11758rce 18751rce 18849rce 19093rce 19106rce 19120rce 32545rce
With the openSUSE patched source, the binary seems to treat /dev/sdb1 as a standard file and reports all open files on the /dev filesystem. That is much worse than the vanilla source does which is a simple failure. -- You are receiving this mail because: You are on the CC list for the bug.
