seem's that you mix disks, partions, and filesystems. Here a little PC-primer that you get an idea what all the other people are talking about.
1. You have a disk - obviously an IDE-drive 'caue the Linux device name is hda.
2. On the disk, you have 2 Partitions, named hda1 and hda2.
3. On the first partition, you have an ext3 filesystem (?) probably for /boot ??, the second partition is the only phisical volume of your volume group VolGrp00 managed by LVM2, countaining several logical volumes.
4. The logical volumes in your volume group VolGrp00 containing are formatted with a ext3 filesystem.
This means, that /dev/hda is an ext3 filesystem ... if that's the case, then the filesystem spans all partiotions and all the logical volumes and if you were able to mount it, you will surely damage all the other stuff on you drive ... well, you can't : i think Linux doesn't allow mounting of overlapping devices/partitions, and if it does, the filesystem is surely already damaged ...Austine,
I have a hard disk of 4.8GB which i partitioned it into 2 parts (hda1 = 100 meg, hda2 = 4.7gb). The whole disk is of ext3 file system type.
The hda2 is managed by using lvm2.
But you said, all drive is ext3 - well, seems you mixed something up ;-)
So you resized the logical volumes, which is a kind of 'virtual partition', but the filesystem is still of the same size, it doesn't recognize the the 'device' or 'partition' it lives on has grown, so you have to tell him to (Jason Martin told you earlier, and pointed you to the LVM-HOWTO <http://tldp.org/HOWTO/LVM-HOWTO/extendlv.html>).Following is the partition sizes of the hda2 disk;
hda2 VolGrp00 4.6 gb
/ VolGrp00/LogVol00 450 meg 35% used /usr VolGrp00/LogVol04 1.9 gb 92% used /usr/local VolGrp00/LogVol05 128 meg 25% used /home VolGrp00/LogVol03 128 meg 60% used /opt VolGrp00/LogVol02 128 meg 35% used /var VolGrp00/LogVol07 450 meg 30 % used swap VolGrp00/LogVol01 342 meg
Here is sequence of steps that i have performed to inc/dec the partition sizes;
tried to increase /usr size by 400 meg.
#lvresize -L +450 VolGrp00/LogVol04
when i display using the "lvdisplay VolGrp00/LogVOl04" i see 2.4 gig allocated to this partition, but when i see it through "df -m /usr" it hasn't changed.
So, As per Jason's email i have done the below;
#lvextend -L2.4G VolGrp00/LogVol04
Instead of complainig you should have better read that doc, and you'd know what to do.
Well, if you'd read the e2fsadm man page before growing your lvol, you'd have known what to do. For an offline ext3 (don't know Fedora, propably they aleady use the online resize patches for ext3 ?), you can use resize2fs to grow your filesystem.
But again this hasn't changed my "df -m /usr" output.
I thought using LVM commands one should be able to take care of the inc/dec of partitions sizes under a given VG. Why should i be using "fdisk" and "e2fsadm" ?
Jason pointed you there in the first reply to your request, so Read That Fucking Manual ;-).
If i have missed or done any thing wrong while resizing the partitions can please provide me an example so that i could try it.
Ciao Klaus
