Details if needed:
I have two disk in one LVM volume group.
I previously created an LV on the disk. When I want to convert
that LV ibnto a mirrored one , i get the error in /var/log/syslog:
> dmeventd[12850]: dmeventd libdevmapper-event-lvm2raid.so dlopen failed:
> libdevmapper-event-lvm2raid.so: cannot open shared object file:
> No such file or directory.
Step to reproduce:
* Create a volume
# lvcreate -L 1G -n lv_test vg_test
* start dmevent and strace it:
# systemctl restart dm-event.service
# strace -f -s256 -p $(pgrep dmeventd) 2> /tmp/mir.log &
* Attempt to convert the disk to mirrored.
# lvconvert -m1 --mirrorlog disk vg_test/lv_test
# dpkg -S libdevmapper-event-lvm2raid.so
