That helped and the kernel no longer sees that partition anymore. However LVM still doesn't work:
cloud:/dev/discs/disc1# vgscan vgscan -- reading all physical volumes (this may take a while...) vgscan -- found active volume group "vg_user" vgscan -- "/etc/lvmtab" and "/etc/lvmtab.d" successfully created vgscan -- WARNING: This program does not do a VGDA backup of your volume group
cloud:/dev/discs/disc1# vgchange -a y vgchange -- ERROR: VGDA in kernel and lvmtab are NOT consistent; please run vgscan
I did a bit of looking around and it seems the confusement is in the kernel: when lvm_check_kernel_lvmtab_consistency() compares the kernel and the lvmtab entries the list from the kernel mentions the vg_user volume group twice, while the lvmtab only mentions it once.
