Hi,
One of my RAID 1 SSD (which contains a VM image) triggered an alert from smartd daemon tonight at 1:27AM:
Zitat von smartd daemonThis message was generated by the smartd daemon running on: host name: nas DNS domain: hidden.tldThe following warning/error was logged by the smartd daemon:Device: /dev/disk/by-id/ata-CT500MX500SSD1_1911E1F0E132 [SAT], 1 Currently unreadable (pending) sectorsDevice info:CT500MX500SSD1, S/N:1911E1F0E132, WWN:5-00a075-1e1f0e132, FW:M3CR023, 500 GBFor details see host's SYSLOG.You can also use the smartctl utility for further investigation.Another message will be sent in 24 hours if the problem persists.

It shows to be solved at 1:57AM. (I assume there is a cron every 30 minutes).
smartctl output shows:

If Selective self-test is pending on power-up, resume after 0 minute delay.

I'm quite used about reading SMART and I can't see any error here... Which is comforting. But in the same time, there was still an error, and I don't like that.
So my questions are:
Do you have any idea what would this error indicate on a SATA SSD?
Is there anything to worry about?
How can there be such an error but nothing in SMART
Any enlightment appreciated.
Best regards
