--- Comment #65 from Andriy Gapon <a...@freebsd.org> --- It could be a combination of what FreeBSD 13 or, more specifically, OpenZFS/FreeBSD does (legitimately) and a bug in drives' firmware or even hardware. E.g., I have a mirror of two SSDs from different vendors. One is 100% stable, the other does the disappearing act at random intervals of time. Actually, recently I replaced the problematic SSD with a new one from yet another vendor, it's 100% stable. If I had to make a guess, then I'd bet on the problem being related to TRIM. But I am not inclined to put my time into a deep investigation of such an "exotic" problem. -- You are receiving this mail because: You are the assignee for the bug.
