Excessive use of the disk I/O
Hi,
I am currently using Vertica version 9.2.1 in which I have hosted different schemas and projects. My problem is that from the vertica console I am seeing that the database disk usage is very high even when there are no ETLs running against the database. How can I reduce this intensive disk usage?

Check which process cause the high disk usage from Linux shell prompt: iotop -n 1 -b -o
If iotop is not installed do: yum install iotop
Does it continue after reboot?
