[Bug 1917414] Re: Ceph-osd fails to start with "error while loading shared libraries: cannot make segment writable for relocation: Permission denied"

[Insanemal]

Hi,

In my case it was in the ceph-osd.0.log

I should paste the log line. Let me just log into the rpi, assuming it's
still on.

2021-03-01T15:01:44.708+0000 ffffa248a040 -1 load: jerasure load: lrc
load dlopen(/usr/lib/aarch64-linux-gnu/ceph/erasure-code/libec_isa.so):
/usr/lib/aarch64-linux-gnu/ceph/erasure-code/libec_isa.so: cannot make
segment writable for relocation: Operation not permitted

Sorry I should have posted the full log line. I did assume it would
cause issues with other libs that were compiled without no-PIC, assuming
that is the issue, and it looks like I might have been right.

I didn't need a mon as this is a OSD node, my mon's are currently
located on faster x86_64 nodes. But it's interesting to see that it
causes issues with MON and OSD services.

Title:
  Ceph-osd fails to start with "error while loading shared libraries:
  cannot make segment writable for relocation: Permission denied"

Status in ceph package in Ubuntu:
  Confirmed

Bug description:
  OSD's fail to start with "error while loading shared libraries: cannot
  make segment writable for relocation: Permission denied"

  The specific library is libec_isa.so

  And it appears to be while the OSD is starting the Jerasure modules.

  I'm going to assume its not compiled with no-PIC which might be a
  hold-over from previous releases?
