Dear all,
I have a strange Problem on a two node cluster, with an DRBD volume.
Each time I try to create a new logical volume I see this error:
c-r0212034:~# lvcreate -L 2G --name foo rep
device-mapper: reload ioctl failed: Invalid argument
Aborting. Failed to activate new LV to wipe the start of it.
I red a lot about this in the internet, but unfortunately it was not
possible to fix it till yet.
Please find some helpful output below:
# pvcreate /dev/drbd0

# vgcreate rep /dev/drbd0

Ooops.
It's not using drbd0, but dm-3 :-(
Either your filter is not what you think it is (maybe you have an other
filter line in the config, and for some reason that one is active, and
not the one you'd like).
Or you simply have to remove the LVM cache and re-scan.

Hi,
Thanks for that answer, I got crazy with this issue. Just forget to
remove the file /etc/lvm/cache/.cache!!
Im so sorry because I annoyed you all with that easy problem.
Best regards,
Markus
