Hi fsmithred,
I'll remove lvm2 and mdadm on this old clunker, but I'll leave off the lv/vgremove stuff.
Thanks for the info.

Hi rolfie,
Thanks for the explanation. I think I'll take your advice to just leave it be. It doesn't cause any issues, so I will ignore it.
Best,
L.

Hi Dutch_Master,
Thanks for the reply - I had a look in the BIOS and couldn't seem to find a way.
However, I rebooted/restarted the desktop and the warning message for the Sensor plugin suggested
$ sudo chmod u+s /usr/sbin/hddtemp
to avoid the Permission denied messages. Once I did this, I could do...
$ hddtemp /dev/sda
/dev/sda: ST3360320AS: 41°C
$ hddtemp /dev/sdb
/dev/sdb: Generic USB SD Reader: S.M.A.R.T. not available
$ hddtemp /dev/sdc
/dev/sdc: Generic USB CF Reader: S.M.A.R.T. not available
$ hddtemp /dev/sdd
/dev/sdd: Generic USB SM Reader: S.M.A.R.T. not available
$ hddtemp /dev/sde
/dev/sde: Generic USB MS Reader: S.M.A.R.T. not available
so it looks like I have some internal card readers that are taking up /dev/sd[b-e]
At least the desktop sensor messages have gone now, & I can live with the boot error messages as they don't interfere with anything - AFAIK.
It gives me something else to search on, too.

Hi,
Apologies if this is a noob question, but I am happy to learn and get my hands dirty if someone can help, please.
On boot, I am getting the following error(s)
[....] Setting up LVM Volume Groups... /dev/sdb: open failed: No medium found
/dev/sdc: open failed: No medium found
/dev/sdd: open failed: No medium found
/dev/sde: open failed: No medium found
As far as I know, I am not using LVM and none of these drives are in my /etc/fstab (only one line for my HDD, based on an a UUID identifier + swap and an NFS share).
Normally I would be happy to ignore it - everything boots fine otherwise - but I am using the sensor plugin on XFCE to display my coretemp-0 CPU temperatures and when my desktop starts I get 4 large warning panels telling me that it cannot read sensor information for /dev/sd[b-e], and I don't know it this is related or not.
I installed Devuan only a month or so ago from devuan_beowulf_3.0.0_amd64_desktop-live.iso written to a usb stick that identified itself as /dev/sdf during install (and has since been removed).
My hardware is quite old - a Hewlett Packard mini-tower that doesn't even have a HDMI port.
Please let me know if I can supply any relevant information. I read the release notes, and have tried a search on these forums for boot AND error and LVM but couldn't find anything I thought was relevant.
advTHANKSance.
