New ssd for the homeserver ordered / 2021-12-21

I noticed syslog messages I don't like:

And a number of other errors on sdb. Time to replace it! I ordered a new ssd. This time a different brand. Current configuration is with 2 Kingston drives with very close serial numbers, so maybe the other drive will give similar issues soon.

The check of the raid1 mirror was also showing differences. I'm waiting for the replacement ssd to show up, and at that moment I will remove the suspect ssd from the array and replace it.

Update 2021-12-24: Writing about the order helped speed things up: I just received notification the replacement ssd is being sent. Which will not show up until after Christmas. I also noticed the problematic Kingston still has warranty, so maybe I can get a replacement for that one too. They came in about 1.5 years ago when I upgraded the storage on the homeserver.
