Hello,
I had created an LVM with 3 iscsi drives. One of the target machines died,
which had 2 of the targets in it. So my lvm now says it has 2 bad devices,
makes sense:
vgscan -P
Partial mode. Incomplete volume groups will be activated read-only.
Reading all physical volumes. This may take a while...
Couldn't find device with uuid 'u1KC7q-D8Bi-qGKp-DJgW-kQ8f-NtB6-GLNuzX'.
Couldn't find device with uuid 'YPyDqn-HD9z-2TDc-ZNXP-d4z9-BLtV-BdM0eh'.
Found volume group "iol_vg" using metadata type lvm2
pvscan -P
Partial mode. Incomplete volume groups will be activated read-only.
Couldn't find device with uuid 'u1KC7q-D8Bi-qGKp-DJgW-kQ8f-NtB6-GLNuzX'.

PV /dev/sda VG iol_vg lvm2 [6.24 GB / 0 free]
PV unknown device VG iol_vg lvm2 [4.16 GB / 0 free]
PV unknown device VG iol_vg lvm2 [1.19 GB / 0 free]
Total: 3 [11.60 GB] / in use: 3 [11.60 GB] / in no VG: 0 [0 ]
So ofcourse I'd like to remove these bad PVs. From what I've found, you
need to do this with the vgreduce command:
vgreduce --removemissing -v iol_vg

However, it doesn't seem to actually remove them!

I'm not sure how to proceed from here. How can I successfully remove the
bad PVs from the VG and then replace them?
Thanks,
