History

#1 Updated by Haomai Wang over 3 years ago

hmm, I think the unparsed uuid problem isn't related to crash. Which tool are you used to deploy? From my view, it seemed dpdk libraries are dynamic linked causing crash.

#2 Updated by Sage Weil over 2 years ago

  • Status changed from New to Can't reproduce

#3 Updated by Chris Holcombe about 1 year ago

I was able to reproduce this locally on a virtual machine with lvm on ubuntu 18.04. It seems that LVM produces UUID's that aren't actually parseable uuid's.

lvdisplay 
  --- Logical volume ---
  LV Path                /dev/ceph-c4ab42c6-3af5-4ce1-af42-2fc554fa4a93/osd-block-67bbb17f-2d55-47c3-ae69-646d3538505b
  LV Name                osd-block-67bbb17f-2d55-47c3-ae69-646d3538505b
  VG Name                ceph-c4ab42c6-3af5-4ce1-af42-2fc554fa4a93
  LV UUID                clN8W5-WZTD-bcQc-cR75-TeoQ-nwII-HfP4am
  LV Write Access        read/write
  LV Creation host, time ceph1, 2018-09-17 23:33:30 +0000
  LV Status              available
  # open                 0
  LV Size                1012.00 MiB

  Allocation             inherit
  Read ahead sectors     0
  Block device           253:0

The value for LV UUID isn't a valid UUID is the problem. It's unique and a string but it doesn't follow the UUID standard from what I can tell.

dpkg -l | grep lvm

#4 Updated by Chris Holcombe about 1 year ago

Note this also occurs with ceph 12.2.7 on bionic. It was installed via cloud archive:

cat /etc/apt/sources.list.d/cloudarchive-rocky.list
deb http://ubuntu-cloud.archive.canonical.com/ubuntu bionic-updates/rocky main

#5 Updated by Chris Holcombe about 1 year ago

Tracing through the source code it looks like I'm barking up the wrong tree. I believe this is saying the /var/lib/ceph/osd/ceph-{id}/fsid file is empty and that's the issue. Not sure why it's not getting created.

#6 Updated by Rainer Krienke 9 months ago

I am just trying to set up ceph 13.2.4-1bionic on a Ubuntu 18.04.2 system and creating an osd I also get the _read_fsid unparsable uuid error. I installed ceph from this repos: https://download.ceph.com/debian-mimic.
