https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D268005 --- Comment #3 from wbe@psr.com --- OK, reporting a problem is certainly better than ignoring it, and that expl= ains why it appeared in 13.1, but that leaves the question of why it's happening= at all and fixing that. As a user, what I see is that rsync to an msdosfs flash drive has appeared = to work for years (FreeBSD 9 - 13.0), even repeatedly to the same drive, mixed with mounting it on a Windows machine and adding and deleting files there w= ith no problems evident, so if there was corruption, it didn't cause any appare= nt problem. Yes, that's not proof. :) Now that the issue has been turned in= to an error, I get "remounting read-only due to corruption" when the error occ= urs and the rsync fails rather dramatically. If corruption really has been happening for years, maybe I've just been luc= ky. When this problem arose, I wrote a script that does "find -newer" and "cp -= p" to the flash drive: that doesn't trigger this problem, even now. rsync to a freshly formatted drive (almost all writes) generally works, too. It's rsy= nc when only some files out of many have changed that pretty consistently dies. I've only seen this with MSDOSFS flash drives. The same size and type of f= lash drive with UFS works fine. I have no data regarding non-flash MSDOSFS driv= es. While I've been using Win10 for repairs, I could try fsck(_msdosfs) if that would be more informative and helpful. -WBE --=20 You are receiving this mail because: You are the assignee for the bug.=
