Yes - POST means POWER ON SELF TEST so after the bios screen and before the NAS-R3 loads.
This issue could be related to some hardware issue memory, disks, RAID, power hit, bad cache.... So what can happen is that the RAID may state the values are ok but our Logical Volume manager may see something different in the sector size or other that the controller is not reporting. I would be on this like hot cakes! I have seen drives go offline then places the controller in degraded mode then you better hope that you have a good hot spare (even that can bite u) or RAID 6.
Anyway I would download the logs from the controller and check them w/ there engineers to be on the safe side.
All our raids are RAID6 so at least we have that comfort. We also run everything on UPS to smooth out any power spikes/dips.
We did have a dying drive that we replaced a week ago on that raid, although I was getting those Open-E error messages before that drive was reporting a problem.
The logs in the Areca controller card don't report anything wrong either.
Is it worthwhile to send you the Open-E logs? If so, please PM me your e-mail address.
This brings up another question I've been wondering: Is there any preventative maintenance I can do to make sure my raids are as healthy as they can be?
Send the logs to link below using the support form, make sure it is registered. Many use the disk scrubbing - topics have been discussed on the forum about this.
