The second case should be needed on shrinking a JFS filesystem, you shrink it, before you shrink the logical volume and thus it doesn´t know to what size to shrink. But on enlarging it can determine the size of the lv cause you enlerge the lv before the fs. Thats at least what I know and how it worked in my tests. As I do not use JFS regularily it was a long time since my last test for one of my Linux trainings, but that means that it worked this way quite a lot of kernels ago already. So I think it should be safe, actually safer than manually giving - a possibly wrong size - to let JFS detect the new size of the volume on growing. > So my question is, if there is some > outage during this procedure, because this filesystem is exported with > NFS > and I need to do it online without any outage. > > Does anybody have > some experiences with JFS resizing? Two ideas: 1) Backup! 2) Try with a test filesystem.
