In order to do disk rotation in a server, I need to know the current running time (online) time of a disk on a Linux CentOS release 6.3 (Final) system.
The disks are connected with SATA (e.g. /dev/sdc), are simple rotating type (Western Digital RE type disks), and are not organized in any RAID or similar.
I have tried to find it using smartctl
(as suggested in How to find out total running time of system and hard disk?), but was unable to find the information. Any suggestion for command ?
smartctl --all /dev/sdc
? You should see a section labeledVendor Specific SMART Attributes with Thresholds
. Do you see any values there? What exactly did you get?
