Is it possible to identify files in use?

I was trying to run DiskWarrior on a volume and kept getting an error message that the volume couldnt be unmounted because some files were in use. Quitting apps didn't help. Is there a way to identify what files are open on this other volume?

lsof -- list open files by process
Applications->Utilities->Terminal $ lsof takes a variety of option switches (which you can see/learn about via $ man lsof happy hunting!)

Any quick, easy way? Due to my lousy text entry skills, I avoid Terminal and know nothing about lavigating in a command line mode.
It would be really nice if Disk Warrior could produce a list of the files in use.

"OPTIONS
In the absence of any options, lsof lists all open files belonging to all active processes. " $ lsof COMMAND . PID . USER . FD . TYPE DEVICE SIZE/OFF NODE . . . . NAME sshd . . . . 21648 dhotay cwd VDIR 14,2 . . 1428 . . . . 2 . . . . . . / sshd . . . . 21648 dhotay 0u . VCHR 3,2 . . 0t0 . . . . . 60880004 . /dev/null ... csh . . .. . 21649 dhotay txt . VREG 14,2 . . 347016 . . 2761. . . . . /bin/tcsh csh . . .. . 21649 dhotay txt . VREG 14,2 . . 1793424 . 1143496 . . /usr/lib/dyld csh . . .. . 21649 dhotay txt . VREG 14,2 . . 4398100 . 1143709 . . /usr/lib/libSystem.B.dylib csh . . .. . 21649 dhotay txt . VREG 14,2 . . 304580 . . 1143863 . . /usr/lib/libncurses.5.4.dylib ... The last column, under NAME, is the file that is open. (dots added to try to preserve vertical alignment)

Did you try just logging out and logging back in and then using Disk Warrior?

Logging out and in; restarting; swearing. I did actually open Terminal and list open files. Would the volume name appear in the file's path name? Everything in the list appeared to be on the boot drive.

Are you using a font manager?
Is it possible you've got some open font files on the volume in question?

It sounds like there are files marked as open in the filesystem itself ( in the Finder database, perhaps?). These will not be listed by the 'lsof' command, which looks at a different set of data in the UNIX/MacOSX '/proc' (process data) directory tree.
Sorry, I don't know what would work for Desktop DB or Finder DB . I think an earlier topic mentioned File Buddy(?) as a possible tool. |
