Re: OSD:s failing out after upgrade to 9.2.0 on Ubuntu 14.04

[Claes Sahlström <claws@xxxxxxxxxxxxx>]

Yes I upgraded from Hammer 0.94.4.

 

And "ceph-osd --version" gives the correct version 9.2.0,  I think it is a problem with the communication between my OSDs and either the MONs or the other OSDs or maybe both.

 

I will check out those archives from Sage also…

 

I have probably done something wrong, but I cannot figure out what is is. All my upgrades before was smooth and this is quite an old installation I have at home.

And if you look through the archives Sage did release a version of Infernalis that fixed if you didn’t do it that way as well.

Did some more logging and for some reason it seems like I do have some

“ceph tell osd.* version” gives two different errors that might shed

I have some quite large logs that I was going through and noticed that I
got this in the osd-log:

2015-11-16 20:27:43.432210 7f6b356a0700  1 osd.0 39502 osdmap indicates
one or more pre-v0.94.4 hammer OSDs is running



That made me check what version the OSDs were, but I get that log entry
is because it cannot check the version of the other OSDs at all.

>From which version did you upgrade?  The release notes for 0.94.4 [0] say:

"This Hammer point release fixes several important bugs in Hammer, as
well as fixing interoperability issues that are required before an
upgrade to Infernalis. That is, all users of earlier version of Hammer
or any version of Firefly will first need to upgrade to hammer v0.94.4
or later before upgrading to Infernalis (or future releases)."
