Hello, We have had 12 Samsung 860 PRO 256GB SSDs in production for a week on Ubuntu 16.04.4 LTS (4.4.0-122-generic). At 06:47am on Sunday, the weekly cron job "fstrim" was run with: `/sbin/fstrim --all`. Afterwards, on 8 out of 12 SSDs, root filesystem was corrupted and remounted read-only as we are using the "errors=remount-ro" option. Any idea why this would happen? Could this be related to https://patchwork.kernel.org/patch/10310641 from March 27? For the time being, we have reinstalled all our servers and disabled the cron job in order to continue production. In the meantime, if you need more information to diagnose the problem, we could buy another Samsung 860 PRO SSD dedicated to running tests.
