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.
