added a physical volume but df reports no joy
hi all.
so when my first logical volume filled up i added a third
physical volume with 'pvcreate /dev/hdx' then
'vgextend vol_group_name /dev/hdx' then 'lvextend -L 53000 /dev/vol_group/log_vol /dev/hdx'. i had 35GB and added another 20GB disk for a possible 55GB but after the lvextend the kernel isn't seeing the new volume size - that is i still only have 35GB of usable storage ( including some PEs that when allocated will have a neglible impact on the total volume size needed ).
is this because set the logical volume size as opposed to extending it?
the logical volume is now at almost %100 and won't take any more data ( sans those extra PEs )
here's a verbose vgdisplay:
glimmung:~# vgdisplay foo -v --- Volume group --- VG Name foo VG Access read/write VG Status available/resizable VG # 0 MAX LV 256 Cur LV 1 Open LV 1 MAX LV Size 255.99 GB Max PV 256 Cur PV 3 Act PV 3 VG Size 54.16 GB PE Size 4 MB Total PE 13866 Alloc PE / Size 13250 / 51.76 GB Free PE / Size 616 / 2.41 GB VG UUID oBe1zH-ifW2-1Lhx-nAGe-UP5t-0Maw-WryAw7

Hi Mark,
After doing an lvxtend, you must also resize the filesystem that resides in the LV. With an ext2fs, this can be achieved using the resize2fs tool that is part of the latest ext2fs tools. Be sure to read the manual page carefully, and maybe even backup your valuable data first!

Nothing can be reasonable or beautiful unless it's been made by one central idea.
ah! yes i realized this this morning!
i'll get that backup started and look at the doc on xfs_growfs.
cheers!
