we have Kafka cluster with RHEL 7.6 , all Kafka are VM machines
on one of the Kafka machines , we noticed that sdb disk became read only ( when sda is the OS disk )
mount | grep sdb /dev/sdb on /var/data/kafka_DB type ext4 (ro,noatime,data=ordered)
from my point of view its little strange that DISK VMDK became read only ( because its not mechanic disk )
from red-hat I find the following
but not sure if above suggestions from redhat are the answer why disk became read only
any others opinions?
