Hi there,
I have setup a LVM2 raid1 mirror with
lvconvert -m 1 --type raid1 /dev/vg_data/lv_test /dev/sdd
and then after I remove one of its legs, the remaining leg keeps on
working just fine. However, I then want to convert this to a simple
Linux volume.
it would fail:
[root@shi-rhel63 ~]# lvconvert -m 0 /dev/vg_data/lv_test
Couldn't find device with uuid QpjTRd-Cc0o-RC0y-7Gz8-GQ4u-25FM-0vO4xt.
Cannot change VG vg_data while PVs are missing.
Consider vgreduce --removemissing.
removemissing not working either
[root@shi-rhel63 ~]# vgreduce --removemissing vg_data
Couldn't find device with uuid QpjTRd-Cc0o-RC0y-7Gz8-GQ4u-25FM-0vO4xt.
WARNING: Partial LV lv_test needs to be repaired or removed.
WARNING: Partial LV lv_test_rmeta_1 needs to be repaired or removed.
WARNING: Partial LV lv_test_rimage_1 needs to be repaired or removed.
There are still partial LVs in VG vg_data.
To remove them unconditionally use: vgreduce --removemissing --force.
Proceeding to remove empty missing PVs.
What should I do in my case to convert the LV to linear?
My OS information:
[root@shi-rhel63 ~]# cat /etc/redhat-release
Red Hat Enterprise Linux Server release 6.3 (Santiago)
[root@shi-rhel63 ~]# uname -a

Thanks a lot.

Following worked for me except I ended up with unclean FS:
lvconvert -m 0 --repair -f vg_data/lv_test

thank you very much.
when i run your command, my machine froze but after reset, the virtual
volumes undet the raid1 are now showing as regular volumes and i was able
to lvremove them and original volume keeps on working.
thanks a lot
