Hi Everybody, I'm expierencing some performance problems with SSVM. /usr/local/cloud/systemvm/ssvm-check.sh shows no problems When the agent is running, I see 100% of io-wait. secondary storage is mounted, but due to the io-wait, I can not access it When I stop the agent(/etc/init.d/cloud stop), I can easily access the nfs mount. I also tried to download images manually (curl), works good. the physical host hos not IO problems /etc/exports: /storage 10.0.40.0/24(rw,async,no_root_squash,no_subtree_check) Mount in the SSVM: 10.0.40.10:/storage/secondary on /mnt/SecStorage/0405ba30-38b9-349d-9ea4-15ea09d67e09 type nfs (rw,relatime,vers=3,rsize=1048576,wsize=1048576,namlen=255,acdirmin=0,acdirmax=0,soft,proto=tcp,timeo=133,retrans=2147483647,sec=sys,mountaddr=10.0.40.10,mountvers=3,mountport=892,mountproto=tcp,local_lock=none,addr=10.0.40.10) Cloudtack: 4.4.3 on centos 7 Please advice what to check Vlad
