That IS the point. I didn't tested PM on Linux, my experience comes from shrinking a FAT32 partition when I first installed Linux (Mandrake at that time). For FAT32, it worked perfectly. Anyway, the only Linux filesystem it sees is ext2. So, when I installed Slackware, there was already a Linux partition there, I just had to reformat it to JFS (no dealing with changing sizes). I'd like to know what's the advantage of resizing a filesystem if there's not such a way to resize the partition in which it lives. Can LVM achieve this - to change the physical partition size (I'm not using LVM right now - I've heard I'd have to convert my filesystem to LVM - is that true?)? PS: Just for curiosity...how new is JFS on Linux ? I know it's quite old on AIX, it was a great surprise when Slackware prompted me with the option to use it... > > > > > Thanks for your help - and for the quick answer, > > You're welcome.
