Hi there,

i have a problem with some newly partioned up disks, i've created two
LVM partions on two different disks.  upon executing the following
commands, vgcreate fails:

[root at box guest]# pvcreate /dev/hde2
pvcreate -- physical volume "/dev/hde2" successfully created

[root at box guest]# pvcreate /dev/hdg2
pvcreate -- physical volume "/dev/hdg2" successfully created

[root at box guest]# vgcreate vg /dev/hde2 /dev/hdg2
vgcreate -- no valid physical volumes in command line


here's a snipit from the tail end of vgcreate -d:

<1> pv_read_all_pv -- calling stat with "/dev/loop/7"
<22> pv_read -- CALLED with /dev/loop/7
<333> pv_check_name -- CALLED with "/dev/loop/7"
<4444> lvm_check_chars -- CALLED with name: "/dev/loop/7"
<4444> lvm_check_chars -- LEAVING with ret: 0
<333> pv_check_name -- LEAVING with ret: 0
<22> pv_read -- going to read /dev/loop/7
<22> pv_read -- LEAVING with ret: -282
<1> pv_read_all_pv -- pv_read returned: -282
<1> pv_read_all_pv -- avoiding multiple entries in case of MD; np: 2
<1> pv_read_all_pv -- LEAVING with ret: 0
<1> pv_check_name -- CALLED with "/dev/hde2"
<22> lvm_check_chars -- CALLED with name: "/dev/hde2"
<22> lvm_check_chars -- LEAVING with ret: 0
<1> pv_check_name -- LEAVING with ret: 0
<1> pv_check_name -- CALLED with "/dev/hdg2"
<22> lvm_check_chars -- CALLED with name: "/dev/hdg2"
<22> lvm_check_chars -- LEAVING with ret: 0
<1> pv_check_name -- LEAVING with ret: 0
vgcreate -- no valid physical volumes in command line



Now, the only thing i can think of, is this disk *used* to have an LVM
on it, (vg+lv) but i have since removed it from the disk, in favour of
this new attempt.  i cant see how it could possibly be a problem, but
maybe there's something lurking in the FS.


Does anyone have any dieas whats wrong?
im running lvm 1.0.3 on 2.4.18
