[Bug 1842020] Re: ceph patch as of 8/29 segfaults all bluestore osds

[Trent Lloyd]

At a super basic level I can't reproduce this. With an eoan container on
an eoan host I don't get a segfault from ceph-bluestore-tool.

I'd suggest we may need to look at getting 
 (1) a coredump
 (2) the somewhat unlikely but not impossible chance that it's CPU-dependent for some kind of optimization reason or similar as this CPU is quite old [can you confirm the install is also 64-bit?]
 (3) A bunch of information about the system configuration.. e.g. from 'sosreport' would work or similar. [I'm not sure if you can use reportbug to upload system info about an existing bug] - including at least the "dpkg -l" full package list.

Title:
  ceph patch as of 8/29 segfaults all bluestore osds

Status in ceph package in Ubuntu:
  New

Bug description:
  The ceph patch on eoan distributed 8/29 crashes all bluestore OSD's
  and is unusable at least on some systems.  Failed on an old dual Xeon
  E5345 box.

  Easy test.  Run:

  /usr/bin/ceph-bluestore-tool

  On working systems it reports a help message.  On the latest eoan release distributed by canonical it
  turns in to an illegal instruction process kill, just after reading /proc/<...>/auxv

  looks like something to do with vsock issues.

  strace -k -y /usr/bin/ceph-bluestore-tool 
  is instructive.

  Notice valgrind against that program reports thousands of memory allocation issues.
  Reverting the system to the snapshot before the apt upgrade restores full operations.
