Yeah, it's usually hanging in some low-level LVM tool (lvs, usually).
They unfortunately like to get stuck indefinitely on some hardware
failures, but there isn't really anything that can be done.
But we've found that it's far more reliable to just call lvs ourselves
instead of relying on ceph-volu

Not sure I follow, would you mind expanding on what you mean by
"ceph-volume unfortunately doesn't handle completely hanging IOs" ?
ceph-volum
Hi Jakub,
"ceph osd metadata X" this is perfect! This also lists multipath devices
which I was looking for!

ceph-volume unfortunately doesn't handle completely hanging IOs too
well compared to ceph-disk. It needs to read actual data from each
disk and it'll just hang completely if any of the disks doesn't
respond.
The low-level command to get the information from LVM is:
lvs -o lv_tags
this allows you
Hi Kevin,
Have you tried ceph osd metadata OSDid ?

If it is freezing, you could maybe try running the command where it
freezes? (ceph-volume will
Hi!
Yes, thank you. At least on one node this works, the other node just
freezes but this might by caused by a bad disk that I try to find.

Hi,
$ ceph-volume lvm list
Does that work for you?

Hi!
Is there an easy way to find raw disks (eg. sdd/sdd1) by OSD id?
Before I migrated from filestore with simple-mode to bluestore with lvm, I
was able to find the raw disk with "df".
Now, I need to go from LVM LV to PV to disk every time I need to
check/smartctl a disk.
