Hi Sage, We have 3 osd failed first, two of them have the same log as osd3 , the other one is osd 7. We just use it as a file system, I wrote a script to repeatedly write a 10G file and delete it. The only unusual thing I saw in the log was the journal file was fulled before the code trace log. The other thing is that when I try to restart the failed osd, more osd crashed on other node. However we didn't get the core dump :( Thanks. Regards, Leander Yu.
