Also, you might prefer to use pvdisplay, vgdisplay and lvdisplay. For example, it will print sizes in physical extents too (in case you want to use -l instead of -L option).
Thank you, Aleksander! All well. Thanks for you explanations, presented very easy to understand.
Only downtime, was to reboot once after fdisk.
# df -h Filesystem Size Used Avail Use% Mounted on /dev/mapper/VolGroup00-LogVol00 36G 5.7G 29G 17% / /dev/hda1 99M 22M 73M 24% /boot none 506M 0 506M 0% /dev/shm
My commands were:
- fdisk /dev/hda
- init 6
- pvresize
- lvresize
- ext2online
Now that this was successful, I am now wishing I left some space for doing snapshots. Is there a way to free up some space so I can get some free PE?
Right now I have this: # vgdisplay --- Volume group --- VG Name VolGroup00 System ID Format lvm2 Metadata Areas 1 Metadata Sequence No 7 VG Access read/write VG Status resizable MAX LV 0 Cur LV 2 Open LV 2 Max PV 0 Cur PV 1 Act PV 1 VG Size 38.22 GB PE Size 32.00 MB Total PE 1223 Alloc PE / Size 1223 / 38.22 GB Free PE / Size 0 / 0 VG UUID 0mB18U-4VRo-1GMC-oKdf-ZndA-slFy-eOQtYD
So, it won't let me do this: # lvcreate -L1G -s -n fullbakup /dev/VolGroup00/LogVol00 Insufficient free extents (0) in volume group VolGroup00: 32 required
Ext2online will not reduce size, so the man page says and I also tried it for the fun of it.
lvresize won't work either.
