Re: resize / (ext3) with no LVM(2) - using fdisk and ext2online - possible?

   Fdisk is not the right tool for it.  It only changes the partition..
   doesn't change the file system..  you will require a utility that can also
   dela with filesystem. Parted fits in well for your requirement.

   I havent tried using it before.. Was always lucky to have data on a LVM
   :).

   The man page says it is possible to extend space without destroying data..
   My suggestion is to back-up data before trying this.. I haven tried it
   myself

   But in ur case you have already changed the partition.. so i am not sure
   how this will work.. best way would be to re-create the same partition
   with fdisk.. then use parted.

   how r u checking your filesystem size? df? df displays size based on fs
   properties.. so even if you have a larger partition without extending the
   filesystem.. that would be the case... to confirm check the /proc/ info
   for exact kernel status of the disks...

 i think i should be able to boot the machine  off a CD and do this - but
 just curious if one can do this from a running OS and reboot if need be

   Partprobe should force your kernel to read your partition table without
   re-booting..  Never edit partitions for file systems which are already
   mounted. if normal data partitons no re-boot would be required.. if any of
   the system partitions are used, you will require rescue CD.

   Do let us know how u r about to burn ur hands. ;)
