RHEL 6.5 shared library upgrade safety

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi Ceph,

In RHEL 6.5, is the following scenario possible : 

a) an OSD dlopen a shared library for erasure-code, 
b) the shared library file is replaced while the OSD is running, 
c) the OSD starts using the new file instead of the old one. 

It seems unlikely but it would explain a weird stack trace at http://tracker.ceph.com/issues/9153#note-5 so I'm double checking ;-)

Cheers
