After do the disk except error check , we found that the disk read is slow gradually after restart the system. but we have not the performance analyse before the disk except error check ,so we can't how to
lead the disk read slowly.
we found the disk read slowly by the db_verify job is slow gradually.
the db_verify command is "brbackup -u / -c force -m all -t online -w only_dbv"
now we don't know the databse reason or hardware lead to the db_verify slow.
