I realized recently, that the Seagate Constellation.2 2.5" drives in my primary NAS have been excessively load-cycling for the past year or so due to them switching to an idle power state that parks the head too often. I noticed when one of them developed two read errors and I replaced it with one of my two cold spares, but that's mostly besides the point.
I probably should have realized what was happening sooner, as I knew the whole time that the drives would "beep" every so often - especially when accessing smart data with
In any event, these drives appear to be too old to work properly with
These drives only have about 9500 hours on them, and about 14,500 load cycles, which is really not as bad as it could have been, so I'd like to make sure they can last quite a while longer.
I probably should have realized what was happening sooner, as I knew the whole time that the drives would "beep" every so often - especially when accessing smart data with
smartctl -a
, but I didn't recognize that as the sound of the head unloading - the more you know.In any event, these drives appear to be too old to work properly with
openSeaChest
, which shows EPC as being supported and enabled, but claims that showing the current settings is not supported, and disabling idle_b
to prevent head parking doesn't seem to "stick" despite the command claiming it was successful. APM is not supported, so setting that isn't helpful either. For now I have just set the smart service to poll the drives every 60 seconds since I don't know what the idle_b
timeout is set to. Given these are enterprise drives, my best guess is it's probably similar to the 2 minutes of the Seagate Exos drives from this thread, but I am wondering if there is any reason why having smartd hit them every 60 seconds could be a bad thing.These drives only have about 9500 hours on them, and about 14,500 load cycles, which is really not as bad as it could have been, so I'd like to make sure they can last quite a while longer.
