resize mounted ext3 partition

How exactly do I go about resizing an ext3 partition (undestructively).

Do I have to use ext2resize? or ext2online? or parted?

What commands will I issue with whatever utility i end up using? Any help would be great.

(the partition I will be resizing is my /dev/hda3 partition and its mount point is '/')

I think it's not wise to resize a mounted ext3 filesystem. Boot from the livecd and use ext2resize.
I've never done it, so I can't tell you the exact command. I use resierfs and the reiserfs tools come with resize_reiserfs which is pretty easy to use

i am currently haveing the same problem..
i like to resize a mounted ext3 partition. this is a webserver, and i cant boot off from the CD ROM. the server is located in a serverfarm ;(

well, maybe something else will achive what i want:
we have a FTP server (proftpd), and i would like to limit the upload dispace. is this possible? i heard about softquota, but AFAIK this does only work if one uses proftpd with SQL, is this correct?

is there any other way to disallow uploads in proftpd, if, lets say, disspace is less then XX Gb?

Perhaps the sys-fs/ext2resize utility can help?

i fixed my problem the following way:

disable swap (1Gb partition). mkfs swap -> ext2 (hda2 in my case)
mounted /usr/potage and /var/tmp to external partition (mount --bind)
bootstrap, emerge system on 1GB drive (the one that used to be swap)
it fits, stage1 2005.0, kernel 2.6
you will have 50MB left if you are done :lol:

ext2resize hda3 to 14GB
fdisk, delete hda3, create hda3, 15GB
ext2resize again - to 15GB this time so you waist no space

reboot back with your normal hda3 and you are done.

btw: this is not for noobs, it did work here, it will probably fail for anyone else. yes, i described it the sloppy way here <g>.
actually, the whole process took a few hours and even more couple of beers :lol:

so, if you are a noob, stay away from this. if you really really know what you are doing, feel free to ask back.

oh, btw.. you might get in trouble compiling glibc without swap. use -j1 in this case, to allow 1 instance of CC only.
phew! back to my beer now
