smartctl can very much read sas drives so I would look into that chain first. Are they behind a raid controller that is masking the smart commands? As for monitoring, we run the smartd service to keep an eye on drives. More often than not I notice weird things with ceph long before smart throws an actual error. Bouncing drives, oddly high latency on our "Max OSD Apply Latency" graph. Every few months I throw a smart long test at the whole cluster and a few days later go back and rake the results. Anything that has a failure gets immediately removed from ceph by me regardless if smart says it's fine or not. At least 90% of the drives we RMA have smart passed but failures in the read test. Never had pushback from WDC or Seagate on it. -paul ________________________________________ From: Marc <Marc@xxxxxxxxxxxxxxxxx> Sent: Thursday, October 13, 2022 4:44 PM To: ceph-users Subject: monitoring drives I was wondering what is a best practice for monitoring drives. I am transitioning from sata to sas drives which have less smartctl information not even power on hours. eg. is ceph registering somewhere when an osd has been created? _______________________________________________ ceph-users mailing list -- ceph-users@xxxxxxx To unsubscribe send an email to ceph-users-leave@xxxxxxx _______________________________________________ ceph-users mailing list -- ceph-users@xxxxxxx To unsubscribe send an email to ceph-users-leave@xxxxxxx
