hi Is it possible to create journaled FS which is crypted with geli? I can create crypted or journaled FS, but it is complicated to me to create both in time, can you help me clue? -- С уважением, Коньков mailto:kes-...@yandex.ru ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org

You have to encrypt first and then create the gjournal device on the .eli device so you end-up with device that ends in .eli.journal. However, FreeBSD 9 supports journaled soft-updates which is much faster than full data journalling, and it can be enabled on existing filesystems. ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org
