Hi,
I recently installed FreeNAS 9.10 on a HP MicroServer Gen 8 with two Seagate Barracuda 7200.14 1TB disks in a ZFS mirror configuration.
All is fine except that in the SMART data I can see that the emergency retract count is going up for both drives each time I turn the server on/off even though I always the GUI shutdown command. Given that the server is used lightly and turned off when not in use, I am a bit concerned for the long term implications this could have. But I'm not sure FreeNAS is the culprit here because the count was already at 10 by the time I first installed it and ran smartctl.
The Microserver has a horribly labourious boot sequence that takes several minutes so I don't know if it could be power cycling them at that point for some unknown reason.
Has anybody run into this issue before?
SmartCtl Output:
Thanks,
James
