https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=228359 Warner Losh <imp@FreeBSD.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |imp@FreeBSD.org --- Comment #2 from Warner Losh <imp@FreeBSD.org> --- "To answer your question directly, no, there is currently no way to ask UFS to TRIM unused filesystem blocks. Of course, gmirror has no way to know whether a given block is used or not, so the problem cannot be solved there. Creating a large file and deleting it is probably the only reasonable workaround for now." Doesn't fsck_ufs -E do this? -- You are receiving this mail because: You are the assignee for the bug.help
