** Also affects: ceph (Ubuntu Eoan)
Importance: Undecided
Status: New
** Description changed:
- Since 'luminous' ceph (and in particular ceph-mon) fails on the s390x
- big endian platform.
+ [Impact]
+ Ceph is not functional on big-endian deployments (s390x)
+
+ [Test Case]
+ Deploy ceph on a s390x (using Juju charms).
+ Monitors will fail to start, OSD's won't bootstrap.
+
+ [Regression Potential]
+ Low, patch has had lots of review upstream and has been accepted into the
nautilus stable branch which is the release Ubuntu has in Focal and Eoan.
+
+ [Original Bug Report]
+ Since 'luminous' ceph (and in particular ceph-mon) fails on the s390x big
endian platform.
A bug for that was already raised in 2017 - LP 1713032:
"[luminous] ceph-mon crashes when it is elected leader (s390x)"
https://bugs.launchpad.net/cloud-archive/+bug/1713032
It was a longer running task to get things fixed for s390x.
And finally uweigand (many thx Uli) got everything accepted upstream:
"Fix big-endian handling #30079" - https://github.com/ceph/ceph/pull/30079
In parallel to that there is also a backport of these s390x endianess fixes
for ceph 'nautilus':
"nautilus: backport endian fixes #30697" -
https://github.com/ceph/ceph/pull/30697
This ticket is to get this upstream checked, tested and partly approved
'nautilus' backport integrated into the UCA ceph 'nautilus'.
