After lvextend wrong free space


Hi there, after much searching I can't seem to find anybody else with this problem!

I run a dual boot machine between Win XP and FC6, with an 80GB SATA hard drive. Recently, with all the software stability enchancements in FC, I decided to make my system primarily Fedora, so resized my NTFS partition to about 30GB, leaving a 3.7GB FAT partition, where I keep the Fedora CD iso images for install purposes.

I then used the lvm gui in fedora to add the unused space to my volume group.

Finally, I used a knoppix live CD to run lvextend, increasing my LogVol00 (which should contain my whole filesystem) to take up the rest of the disk.

I should now have 46.56GB of total space available to fedora, and indeed lvm seems to think i do;

Code:
lvm> lvs
  LV       VG         Attr   LSize  Origin Snap%  Move Log Copy% 
  LogVol00 VolGroup00 -wi-ao 46.56G                              
  LogVol01 VolGroup00 -wi-ao  1.00G
However, df shows this;

Code:
[root@aibr ~]# df -h
Filesystem            Size  Used Avail Use% Mounted on
/dev/mapper/VolGroup00-LogVol00
                      8.0G  6.2G  1.4G  83% /
/dev/sda3              99M   16M   78M  17% /boot
tmpfs                 252M     0  252M   0% /dev/shm
/dev/sda1              26G   24G  2.3G  92% /ntfs
It seems that everything else on the system agrees that I only have 3GB left, as when I tried to copy a 7GB backup file over it told me I didn't have enough space.

Where has my space gone?!

Sorry if this is something really obvious, but I just can't understand why I'm getting two different results!

Many thanks in advance.
Jim

The obvious part you are missing is that you didn't extend your file system. Extending the LV is like extending a hdd partition, it doesn't affect the file system itself.
Assuming your file system is ext3, you need to unmount the LV and do a "resize2fs". As it's your / partition, do it from Knoppix.

See also this thread.

Thumbs up

*blush*

That did it nicely (for some reason it didn't work from Knoppix, but fortunately as Im using kernal 2.6 I could do it with the filesystem mounted.

Thanks very much, sorry for the noobishness

Now you got me interested... last time I tried to do it online it didn't work. It was a 2.6 kernel also.
Didn't you get any error message at all, or any warning?
Which kernel? (mine is 2.6.17.13)
Which version of resize2fs? (mine is 1.38)
