Hi,
I'm unable to create PVs on Multipath-Volumes that are available at
/dev/dm-NN where N~[0-9] but I can create them on single digit devices
like /dev/dm-9:
# pvcreate /dev/dm-6
Physical volume "/dev/dm-6" successfully created.
# pvcreate /dev/dm-16
Device /dev/dm-16 not found (or ignored by filtering).
My Version of LVM is 2.02.168 from Debian 9.
The filter ist set to a permissive value:
filter = [ "a|.*|" ]
global_filter = [ "a|.*|" ]
Any ideas why two or more digits in the device path can cause it to be
filtered by pvcreate?
Hi
lvm2 is detecting multipath 'component' devices - those are not allowed to be
used for pvcreate.
You can use 'pvcreate -vvv' to get more information - there will be printed
the reason why devices are rejected....
Eventually if you can't figure this out yourself - provide this trace in
attachment.
Regards
Zdenek
