[linux-lvm] New lv cannot span pv's

[Stefan Nilsen]

Hi.

I'm using LVM on SuSE 8.1

As can be seen below, I cannot create a logical volume spanning physical 
volumes even if they are in the same volume group.

I'm pretty sure I could do this in older versions of the LVM.

wale:~ # pvscan
pvscan -- reading all physical volumes (this may take a while...)
pvscan -- ACTIVE   PV "/dev/hda5" of VG "vgdata" [11.60 GB / 3.16 GB 
free]
pvscan -- ACTIVE   PV "/dev/hda6" of VG "vgdata" [21.71 GB / 3.24 GB 
free]
pvscan -- total: 2 [33.31 GB] / in use: 2 [33.31 GB] / in no VG: 0 [0]

wale:~ # lvcreate -ntest -L5G vgdata
lvcreate -- not enough allocatable/free physical volume space in 
"vgdata"
lvcreate -- please check, if physical volumes are allocatable

Do I really have to use MD to overcome this problem?
Shouldn't the LVM software take care of this?

What does vgdisplay show?

Does

lvcreate -ntest -l1383 vgdata


work ?

It did not.

wale:~ # lvcreate -ntest -l1383 vgdata
lvcreate -- not enough allocatable/free physical volume space in 
"vgdata"
lvcreate -- please check, if physical volumes are allocatable

I looked around little more and found this:

wale:~ # pvdisplay /dev/hda5
--- Physical volume ---
PV Name               /dev/hda5
VG Name               vgdata
PV Size               11.61 GB [24338412 secs] / NOT usable 3.99 MB 
[LVM: 134 KB]
PV#                   1
PV Status             available
Allocatable           NO
Cur LV                5
PE Size (KByte)       4096
Total PE              2970
Free PE               553
Allocated PE          2417
PV UUID               eQxblH-x1uS-bb9G-reYu-ocZo-QSOW-5j6QB0

I seem to have managed to turn off the allocatable status of one of the 
pv's. :-)

I changed it with "pvchange -xy /dev/hda5" and now it works.

Thanks for help.
