Maximum file sizes on differrent file systems

I was looking up the maximum file size on a file system for a friend, and I realised I didn't even know this stuff. Here is a couple:
FAT32: 4 GiB
NTFS: 16 EiB
ext2 and ext3: 16 GiB to 2 TiB (see this note about max range)
ext4: 1 EiB
ReiserFS: 8 TiB
HFS plus (used by Apple's Mac OS X): 8 EiB

Set partition labels on linux.

My colleague Elardus complained that my flash drive didn't have volume labels set and I also wanted automounting to make a nice consistant mountpoint eg. /media/my_flash_drive.
I didn't think think it would be that hard, I really thought that a gui like gparted or qtparted would be able to do that, but was disappointed. So I had to do it from the commandline.

To set the label for ext2 or ext3 partitions:

sudo e2label /dev/sdb2 new_label

where /dev/sdb2 is the partition you want to label. (To get a list of mounted partitions you can do `df -ahT`)


For FAT partitions you first need to configure the drive:
you have to edit /etc/mtools.conf, make f: drive be /dev/sdb1

sudo mlabel f:new_label

Initially I got the following error.

Total number of sectors (256976) not a multiple of sectors per track (63)!
Add mtools_skip_check=1 to your .mtoolsrc file to skip this test

I just did what it asked and then it worked:

echo "mtools_skip_check=1" > ~/.mtoolsrc
