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

[James Page]

Attempting to reproduce:

$ apt-cache policy ceph-osd
ceph-osd:
  Installed: 14.2.2-0ubuntu2
  Candidate: 14.2.2-0ubuntu2
  Version table:
 *** 14.2.2-0ubuntu2 500
        500 http://gb.archive.ubuntu.com/ubuntu eoan/main amd64 Packages
        100 /var/lib/dpkg/status

$ ceph-bluestore-tool
must specify an action; --help for help

$ ceph-bluestore-tool --help
All options:

Options:
  -h [ --help ]          produce help message
  --path arg             bluestore path
  --out-dir arg          output directory
  -l [ --log-file ] arg  log file
  --log-level arg        log level (30=most, 20=lots, 10=some, 1=little)
  --dev arg              device(s)
  --devs-source arg      bluefs-dev-migrate source device(s)
  --dev-target arg       target/resulting device
  --deep arg             deep fsck (read all data)
  -k [ --key ] arg       label metadata key name
  -v [ --value ] arg     label metadata value

Positional options:
  --command arg          fsck, repair, bluefs-export, bluefs-bdev-sizes, 
                         bluefs-bdev-expand, bluefs-bdev-new-db, 
                         bluefs-bdev-new-wal, bluefs-bdev-migrate, show-label, 
                         set-label-key, rm-label-key, prime-osd-dir, 
                         bluefs-log-dump


That said I'm running on a much new processor type.

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.
