[lejeczek]

Hi guys.

What is the issue here?

-> $ lvs
   Devices file sys_wwid eui.6479a73050830000 PVID none last 
seen on /dev/nvme1n1p4 not found.
   LV   VG       Attr       LSize   Pool Origin Data%  Meta% 
Move Log Cpy%Sync Convert
   devs cs_whale -wi-ao---- 844.23g
   root cs_whale -wi-ao---- 40.00g
   swap cs_whale -wi-ao----   7.54g

-> $ lvmdevices --deldev /dev/nvme1n1 ; echo $?
   Devices file sys_wwid eui.6479a73050830000 PVID none last 
seen on /dev/nvme1n1p4 not found.
   Device not found in devices file.
5

-> $ lvmdevices --deldev /dev/nvme1n1 --devicesfile 
eui.6479a73050830000; echo $?
   Device not found in devices file.

many thanks, L.

That device was added to the lvm devices file at some point (see
/etc/lvm/devices/system.devices), but the device no longer exists.
If that device won't be reattached or if you don't want lvm to use it,
then it should be removed from system.devices.

That's the right idea, but two issues,

1. lvmdevices --deldev is missing the ability to remove a missing device
   by name (or by wwid), and that will be fixed.
2. when that's fixed, you'd need to use the name /dev/nvme1n1p4

Until that's fixed, edit system.devices and remove that line.
