Removing vg and lv after physical drive has been removed

Solution 1:

The solution was to run dmsetup, in this case the two commands

dmsetup remove vg04-vz
dmsetup remove vg04-swap

Before doing this, I checked with the command 'dmsetup info' that the 'open count' for both LV's were zero.

WARNING: dmsetup can wreck serious havoc with your disks so anyone using this information in the future please make sure you read the man page.

Solution 2:

I experienced similar after removing a VMware disk /dev/sdb.

Use lsscsi to determine which device is being used (you may need to install the program) then run lsscsi:

# lsscsi
[1:0:0:0]    cd/dvd  NECVMWar VMware IDE CDR10 1.00  /dev/sr0
[2:0:0:0]    disk    VMware   Virtual disk     1.0   /dev/sda
[2:0:1:0]    disk    VMware   Virtual disk     1.0   /dev/sdb <== the removed physical disk
[2:0:2:0]    disk    VMware   Virtual disk     1.0   /dev/sdc

Now write the delete file with

# echo 1 > /sys/class/scsi_device/2\:0\:1\:0/device/delete

The device is immediately gone.

Solution 3:

vgchange -a n /dev/vg04

If you have logical volumes still active you may have to

lvchange -a n /dev/vg04/swap
lvchange -a n dev/vg04/vz

etc.
