[Dell] Ȥ ̷Ȳ ޾ź Ű..?

   ȸ 3298   õ 0    

최근에 점검하다가 발생한 상황인데.. 처음겪는 일이라 당황스럽네요 ㄷㄷ

Dell R440 모델에

CPU는 제온 골드 5222 4코어 * 2

메모리 32G

디스크 1.2TB 2개에 레이드1로 묶어서 쓰고있습니다.


이게 문제가.. CPU 점유율이 어느순간 보니 7~80%를 찍고있더라구요

평소 많아야 2~5%인데.. 올라가있는 서비스 전부 disable시키고 재부팅 시켜봤습니다.

재부팅 후 nmon으로 cpu 상태를 봤는데

???

CPU1번만 미친듯이 돌아가고 있네요(재부팅 직후 상황입니다 저게)

top로 프로세스를 봐도 많아야 0.3?밖에 cpu점유를 안하는데.. 왜저러는지 모르겠습니다 ㅠㅠ


idrac 로그를 봐도 전부 정상인걸로 나오고.. 희안하네요 참

조만간 바이오스랑 idrac 펌웨어 올려보고 CPU 스왑도 한번 해볼 예정입니다.


이런 비슷한 상황 겪으신분 계신가요? 있으시면 어떻게 조치했는지 궁금합니다.

There are 2 things that I know of that cause NMON to report different CPU usage stats than topas and vmstat. I believe these are design decisions in NMON rather than bugs.
The first thing is SMT. I was at a presentation that Nigel gave and he discussed the difficulties that SMT posed in determining what 100% was for a Power5 core/cpu. When SMT is turned off, the system sees 1 logical CPU for each physical (or virtual in micropartition LPARs) CPU. Lets assume that 1 logical CPU can perform 100 units of work. When it is doing 100 units of work, it is 100% busy.
