Hi all,
When I make a fio-rbd-test, it says segmentation fault. I reckon that
there may be something wrong with the usage of libnss.
Ceph version is 11.2.0 (f223e27eeb35991352ebc1f67423d4ebc252adb7)
using AsyncMessenger.
Is libnss3.so thread safe? or other thoughts to resolve this problem?
Here is the output of #gdb /usr/bin/fio corefile
......
warning: the debug information found in
"/usr/lib/debug/usr/lib64//librados.so.2.0.0.debug" does not match
"/lib64/librados.so.2" (CRC mismatch).
