lvm vgcreate fails with ignored devices
Issue
Running vgcreate with devices that are ignored fails to create a VG even though there are also good devices included in the command.
The parameter "pv_min_size = 10240" has been set so the system ignores certain devices below 10MB in size.
This is added to /etc/lvm/lvm.conf
# Ignore devices smaller than 2MB such as floppy drives.
pv_min_size = 10240
Example:
vgcreate new_testvg /dev/mapper/mpathb /dev/mapper/mpathc
/dev/mapper/mpathb # good device > 10MB it is 33GB
/dev/mapper/mpathc # bad device < 10MB
output of command:
[root@host lvm]# vgcreate new_testvg /dev/mapper/mpathb /dev/mapper/mpathc
Device /dev/mapper/mpathc not found (or ignored by filtering).
Unable to add physical volume '/dev/mapper/mpathc' to volume group 'new_testvg'.
Expected result:
The VG new_testvg should be created with the good device and the ignored one should be ignored as it says it is.
Actual result:
no VG is created.
