Hi,
perhaps I have a misunderstanding in concept, therefore I am
glad for each assistance:
My plan is, to remove a partition (/dev/hda4) from lv and use
it seperatly (mount it on /usr).
I tried pvmove and get errors:
root at icezentral:/home/muessig > pvmove /dev/hda4 /dev/hdb1
pvmove -- moving physical extents in active volume group "daten"
pvmove -- WARNING: if you lose power during the move you may need to
restore your LVM metadata from backup!
pvmove -- do you want to continue? [y/n] y
pvmove -- not enough free/allocatable physical extents
Than I used pvscan to check pv and see, there are no extends
allocatable (on each partition 0 free). How is that possible?
df tells me, there enough space available.
root at icezentral:/home/muessig > pvscan
pvscan -- reading all physical volumes (this may take a while...)
pvscan -- ACTIVE PV "/dev/sda1" of VG "daten" [8.51 GB / 0 free]
pvscan -- ACTIVE PV "/dev/sdb1" of VG "daten" [8.51 GB / 0 free]
pvscan -- ACTIVE PV "/dev/sdc1" of VG "daten" [4.25 GB / 0 free]
pvscan -- ACTIVE PV "/dev/hda4" of VG "daten" [5.05 GB / 0 free]
pvscan -- ACTIVE PV "/dev/hdb1" of VG "daten" [57.27 GB / 0 free]
pvscan -- total: 5 [83.59 GB] / in use: 5 [83.59 GB] / in no VG: 0 [0]
root at icezentral:/home/muessig > df -h
Filesystem Size Used Avail Use% Mounted on
/dev/hda3 2.5G 2.2G 163M 94% /
/dev/hda1 15M 3.3M 11M 23% /boot
/dev/daten/1 84G 22G 61G 27% /daten
shmfs 238M 0 238M 0% /dev/shm
Can anybody explain me, whats going on?
Thanks in advance, Peter
