NextCloudPi HDD health notification

citizenserious · April 8, 2022, 1:05pm

Hi there,

I am getting this notification in my nextcloud instance over and over again:

NextCloudPi HDD health CurrentPendingSector
Device: /dev/sda [SAT], 1 Currently unreadable (pending) sectors

NextCloudPi HDD health OfflineUncorrectableSector
Device: /dev/sda [SAT], 1 Offline uncorrectable sectors

I know, that this means that the condition of my SSD is bad, but I have a few questions though.

How bad is it really? The count of “1” did not rise since the notifications started a couple of weeks ago.
I formatted the SSD in hope that it corrects itself, but after a few days this notification showed again.
I also performed a smartctl long test, with this result:

Selective Self-tests/Logging not supported

Can I get rid of the frequent notification? I really want to know if my drives condition is bad or worsens, but if the count stays at “1” the notification twice a day is very annoying. So is there a way to calibrate this?
Any general advice? Would you change the drive immediately?

Thank you very much (:

Just in general: I’d check a bit the details of which is most critical in the smart status for a given device. And, like you already mentioned, monitor the status if it is degrading or not.

Backup your data and your system, that you won’t lose anything once the disk fails.

citizenserious · April 11, 2022, 9:51pm

Thank you for your advice (: I already do regular backups.
As I understand the output of smartctl, the power-on lifetime expired, but I could misinterpret it. The life time per se should not be an primary issue in my understanding, but I do not prefer turning of the HDD health notification, but it is getting really annoying because of the “high” frequency of it . When turning it off I will not be notified if the SSD really worsens.
