Good morning, in order to post proper documentation, what logs (or log level) do I need to troubleshoot a Centos 7.6.1810 3.10.0-957.27.2.el7.x86_64 tha tis running a NFS server on top LVM on top of XFS on top of VDO on top of MDAM on a 6 SSD disk RAID6 ? This physical NFS server is servign 2 NFS v4.2 shares to 2 physical KVM virtualization hosts. When remote NFS clients start doing intensive stuff (massive writes) , the NFS server crashes and sometimes make the Linux server reboot. form KVM side this is all I get: hvm002 kernel: nfs: server 10.10.10.2 not responding, timed out thanks --------------------- Erick ---------------------
