Hello Everyone, I have vertica 9 installed on 3 linux RHEL nodes. After a restart on the servers the database is down and can't be started. I checked the dbLog file and found this error : unable to connect via UNIX socket to /opt/vertica/spread/tmp/4803 (pid=14883): Error: No such file or directory. the file 4803 which is missing seems to be the cause of this failure. Would you please suggest any solution ? Thanks

    Hi,

    Did something change with the network? Like a subnet change?

    How are you restarting the DB? What command?

    Note that the /opt/vertica/spread/tmp/4803 file only exists when the DB is up.

    [dbadmin@SE-Sandbox-26-node1 ~]$ ps -ef | grep [4]803
