[kubelet-check] The HTTP call equal to 'curl -sSL http://localhost:10248/healthz' failed with error: Get http://localhost:10248/healthz: dial tcp 127.0.0.1:10248: connect: connection refused.
Solution is very simple:
SWAP must be disabled in K8S nodes
simply run those command by root and restart the machine:
sudo swapoff -a
sudo sed -i '/ swap / s/^/#/' /etc/fstab

mount.nfs: backgrounding

if you face this kind of error with your remote NFS: [root@Vertica000 ~]# mount /files/application/Rremote3 mount.nfs: backgrounding "10.0.0.2:/files/application/remoteFiles" mount.nfs: mount options: "bg,hard,nointr,rsize=65536,wsize=65536,tcp,actimeo=0,vers=3,timeo=600,addr=10.0.0.2" look for the problem in the log file: cat /var/log/messages | grep mount  mount to NFS server '10.0.0.2' failed: timed out, retrying Solution: In most of the cases, you have a problem with your iptables in the destination server login as root to dest server (10.0.0.2) in my case and type this command: iptables --flush  the go back to your origin server to try remount the problematic NFS file system of course this is in case nfs server was installed and functioning properly. Good luck.

ora-65035 while create pluggable database from another one

or : ORA-21000: error number argument to raise_application_error of -65035 is out of range Cause: this error caused because of an unrecoverable transaction in the source DB. Solution: 1. either stop and start your pluggable source DB 2. identify the open transaction and kill it if you can. use this query to do so: select * from v$transaction t,v$session  s where t.ses_addr = s.saddr;
