This is another useful script, which do a complete erase and test disk in linux.
\nThe first, we must have a tools “smartmontools”. We install it:<\/p>\n

yum install smartmontools<\/pre>\n
Maybe, we nee som usefull software:<\/p>\n
yum install epel-release.noarch\nyum install htop dstat lm_sensors.x86_64 hddtemp<\/code><\/pre>\n

This is fully automatized. We can start this script with modification of variable $test for more disks. And next day, we can examine logs. For bad blocks, for smart self-test and other.<\/p>\n ","protected":false},"excerpt":{"rendered":"
