Do you have the possibility to stop/unmount cephfs clients ? If so, do that and restart the MDS. It should restart. Have the clients restart one by one and check that the MDS does not crash (by monitoring the logs) ________________________________________________________ Cordialement, *David CASIER* *Ligne directe: +33(0) 9 72 61 98 29* ________________________________________________________ Le sam. 24 févr. 2024 à 10:01, <nguyenvandiep@baoviet.com.vn> a écrit :
