Can anyone explain this for me? I added a new hard drive to my LVM and
while lvdisplay of the LVM shows the full size of all disks/partitions in
the LVM, df -k does not:
[root at bergamo sbin]# lvscan
lvscan -- ACTIVE "/dev/lvm01/1" [176.76 GB]
lvscan -- 1 logical volumes with 176.76 GB total in 1 volume group
lvscan -- 1 active logical volumes
[root at bergamo sbin]# lvdisplay /dev/lvm01/1
--- Logical volume ---
LV Name /dev/lvm01/1
VG Name lvm01
LV Write Access read/write
LV Status available
LV # 1
# open 1
LV Size 176.76 GB
Current LE 45251
Allocated LE 45251
Allocation next free
Read ahead sectors 120
Block device 58:0
[root at bergamo sbin]# df -k
Filesystem 1k-blocks Used Available Use% Mounted on
/dev/hda6 10317796 3808332 5985348 39% /
/dev/hda1 62193 17850 41132 31% /boot
none 95628 0 95628 0% /dev/shm
/dev/lvm01/1 115382824 63615676 47078212 58% /mnt/lvm01.01
So while lvm shows the lvm size to be 176.76G, df -k shows the filesystem to
be about 115G. What is happening with this?
Another issue that I seem to be having is that the new PV that I created
from /dev/hdd shows only 8G free from pvscan/pvdisplay:
[root at bergamo sbin]# pvscan
pvscan -- reading all physical volumes (this may take a while...)
pvscan -- ACTIVE PV "/dev/hdd" of VG "lvm01" [111.79 GB / 8 MB free]
pvscan -- ACTIVE PV "/dev/hda5" of VG "lvm01" [26.82 GB / 0 free]
pvscan -- ACTIVE PV "/dev/hdb1" of VG "lvm01" [38.16 GB / 0 free]
pvscan -- total: 3 [176.78 GB] / in use: 3 [176.78 GB] / in no VG: 0 [0]
[root at bergamo sbin]# pvdisplay /dev/hdd
--- Physical volume ---
PV Name /dev/hdd
VG Name lvm01

Obviously I'm doing something wrong here - but I can't figure it out.
Does anyone have any suggestions? At this point, I'd be willing to yank
/dev/hdd out of the volume group, but I can't find out how to do that
either.
Thanks, Ed Jackson
