https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=224479 --- Comment #24 from Mark Millard <markmi@dsl-only.net> --- (In reply to Andriy Gapon from comment #23) [Ignore if you care not for my history and opinion for swapfile usage vs. partition usage.] I will note that when I ran into the deadlock problems from using a swapfile instead of a partition, it was not obvious at the time that swapspace handling was involved at all: it was also first use of a platform as well. I was not lucky to have changed just one thing to know to revert it. For all I knew the type of platform might have been having problems in general. It was a pain to figure out that swapfile use was what I could avoid using in order to avoid the hangups that were happening. To me the discovery seemed to mean that FreeBSD violated a variation on the principle of least astonishment (but not tied to changes to historical behavior). (Having a partition with UFS and only one user-file, the swapfile, might avoid some of the issues. I had done this earlier [by an accidental choice] on powerpc64 and powerpc and had not seen any problems. This contributed to my not challenging the swapfile use earlier in trying to isolate contributions to the hangups: I did not then realize that I'd done something possibly special in that earlier use.) -- You are receiving this mail because: You are the assignee for the bug.help
