gpt zfs booting - loader takes 25s
I've recently installed a ZFS-only system which is booting from GPT using a 'legacy' BIOS. Something I noticed straight away is that the loader takes a very long time: it pauses after enumerating the disks but before displaying information about the installed memory: BTX loader 1.0.0 BTX version is 1.02 Consoles: internal video/keyboard BIOS drive C: is disk0 BIOS drive D: is disk1 BIOS drive E: is disk2 BIOS drive F: is disk3 - pauses for 25 seconds, with the spinner occasionally moving BIOS 631kB/3666816kB available memory Is it normal for booting to take such a long time when booting from GPT? -- Bruce Cran ___ 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

I noticed my VPS takes a bit when I've done a hard reboot, but not when I let it go through all the nice sync, even though there aren't any console messages.

I'm doing a clean reboot, and I don't remember it taking this long when I had a ZFS-only system booting from a disk with an MBR scheme. -- Bruce Cran ___ 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
