https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D218026 --- Comment #1 from Chris Hutchinson <portmaster@bsdforge.com> --- OK. I use the USB3 flash stick I mentioned above, for dumps, and other important backups. Today, in an attempt to experiment with the 12-CURRENT install I have a fresh dump on the stick for. I plugged in a USB2 external drive, and bounced the box, with the intention of performing a restore(8) to the external drive. I forgot that I had an install of ghostbsd on that external drive, and given that I usually have a USB DVD plugged into that port, it booted to ghostbsd. So I simply bounced the box, and changed the boot order in the BIOS, and booted single-user to my 12-CURRENT. performed the following (to the external [usb] drive): gpart destroy -F da0 gpart create -s GPT da0 gpart add -t freebsd-boot -l usbboot -b 40 -s 512k da0 gpart bootcode -b /boot/pmbr -p /boot/gptboot -i 1 da0 gpart add -t freebsd-ufs -l usbroot -s 8G da0 gpart add -t freebsd-swap -l usbswap -s 3G da0 gpart add -t freebsd-ufs -l usbvar -s 55G da0 gpart add -t freebsd-ufs -l usbusr da0 followed by a newfs -U /dev/gpt/usbroot newfs -U /dev/gpt/usbvar newfs -U /dev/gpt/usbusr then individually mounting those to /mnt followed by a restore(8) to each. Bounce the box, change boot order in BIOS, and new usb external drive is not listed. Booting into single-user from main drive reveals secondary table is corrupt! Same is true on the usb stick I keep the dumps on. Before performing any of the above. I am forced to perform gpart recover on the usb stick && an fsck. Both return good status. What to do? I can now see this is not limited to USB3, as the external drive is on a USB2 port. This is a real problem! Thanks for anything that might fix this! --Chris FreeBSD 12.0-CURRENT #0 r314700 --=20 You are receiving this mail because: You are the assignee for the bug.=
