Drive 4 of my 5 year old DL4100 NAS failed S.M.A.R.T. with a code 3. Not surprising (I was expecting a failure for some time due to the age/usage of the device), I even ordered a new PR4100 on Friday.
What was surprising is that I didn’t know about it because the NAS has quit sending notifications. I have it set to send “Critical and Warning” alerts; but did not receive a single e-mail regarding the drive status.
I have already replaced the drive and rebuilt the RAID array; but the e-mail problem described herein persists. There are no other errors on Scan Disk or Quick Test. Tried unsuccessfully to run a Full Test, but it stops at about 10% and hangs with no progress even after 2-3 hours.
Other than adding a share or user, here and there, and firmware updates, this NAS configuration hasn’t changed in five years.
I know this functionality has worked in the past, because I still have some of the old alerts filed away from a few years ago. So, I tried sending a test e-mail, to no avail. I searched this community/site and tried the scant few suggestions, also to no avail. I tried searching the net for possible causes, to no avail.
It gets more confusing because if/when I send/resend a user’s MyCloud notification, the e-mail is sent (and received). E.g., resending a My Cloud notification to a user with the same e-mail address as the alert notifications succeeds; but sending a test notifications e-mail to the same address does not. So I know the Yahoo! mail server is not rejecting the no reply e-mail. I also tried deleting the e-mail address and adding it back, to no avail. I also tried changing the user e-mail to a different account on the same mail server, to no avail. I also tried changing it to accounts on two other mail servers, which includes G-Mail, and it [seemingly] does not send alert notifications or test e-mails.
Until the new NAS arrives, and I back up the data from this server, I did not want to try anything radical like restoring to factory settings or anything like it. I am assuming that this is something simple on my side that I can change or a bug/misconfiguration on the WD side that I cannot [change].
Does anyone have any idea what might cause this? More importantly, does anyone have any idea how to fix it?
Thanks in advance for your response.
- DL4100
- 8TB RAID 10 (16GB total–4x4TB drives)
- Current Firmware Version: 2.31.204
- Connected to a managed 802.3ad LAG/LACP switch, which is connected to a router. I can reach the Internet from the box–see My Cloud e-mail test above. I can also reach the box from the Internet via files.mycloud.com. I.e., connectivity is not the issue.
***NOTE: Current capacity is > 95%, which is the reason I bought a new PR4100. I doubt this is related; but you never know.
***NOTE: I have not tried rolling back the firmware to an earlier “known working” version; but due to the lack of posts on this issue, I doubt a firmware bug is the cause.
