What you have done with the commands below is to resize the logical volume and partition - not the file system that reside on that logical volume/partition. the df or du commands are only considering file system space actively accessible to the OS, which is why you are not seeing a change in /usr partition. The next step is to "grow" or resize the file system on /usr to fill the addtional space on VolGrp00/LogVol04 The simplest way would probably be to umount /usr, the use the resize2fs command to grow the file system. This command works for both ext2 and 3. I'm not terribly familiar with resize2fs, as I mostly manage reiserfs, but the man page is very straightforward: http://www.zevils.com/cgi-bin/man/man2html?resize2fs+8 And the command will probably be something as simple as "resize2fs /dev/VolGrp00/LogVol04 [or your specific device]". According to the man page, if you are wanting to extend to the full size of the partition, you do not need to specify the size - that is the default interpretation of the command. The e2fsadm command is basically a combination of these two steps - it grows the LV and the ext2/3 filesystem at the same time. But, since you've already resized the LV, you only need to grow the file system to match. Hope that helps!

The whole disk is of ext3 file system type.The hda2 is managed by using lvm2. 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 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" ? 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. Thanks. _______________________________________________ linux-lvm mailing list linux-lvm@redhat.com https://www.redhat.com/mailman/listinfo/linux-lvm read the LVM HOW-TO at http://tldp.org/HOWTO/LVM-HOWTO/
