Need to find mount point for device.

[NateTut]

On a Sun box I'm trying to find what files certain processes have open. I'm to the point where by using Proc::ProcessTable and the pfiles function on Sun (I don't have root privileges to us lsof) I can get the following information back for each of the files:

            'Device' => '283,0',
            'Create Mode' => 'O_RDWR FD_CLOEXEC',
            'File Number' => '5',
            'Group ID' => '14700',
            'Mode' => '0000',
            'Size' => '0',
            'Type' => 'S_IFIFO',
            'Inode' => '1877643288',
            'User ID' => '5800'

I know I can use find to find the file name from the inode, but I'm having trouble getting from a device like '283,0' to a mounted file system I can search.

Searches have turned up too many results and the several CPAN modules I've tried haven't worked out. Can anyone recommend a good module I can use for this? Also I would love a module that could return a list of open files given a Pid, but I haven't been able to find anything like that.

Untested, but I'd do something along the lines of:

Run a recursive detailed listing of /dev and grep for the major & minor numbers - in this case 283 & 0 e.g. find /dev -ls | perl -ne 'print if /\s283,\s+0\s/' - this will give you the dev entry e.g. /dev/c1t2d3s0, then simply grep this out of the mounted device list e.g. mount | grep '/dev/c1t2d3s0'.

You might try Solaris::Procfs and in particular its fd method.

Sys::Filesystem::MountPoint will help you find the mount point for any given path. Check out the examples to see if this can solve your problem.
