During boot situation resembles what was shown previously at: https://lists.freebsd.org/pipermail/freebsd-fs/2013-September/018246.html 1. Gmirror grabs partitions for two devices (swap/boot) 2. ZFS fails to mount root with error 22. 3. random: unblocking device 4. ZFS retries mount and fails again, exits to debug prompt. Setting vfs.mountroot.timeout to 300 just makes kernel output another error each ~12 seconds. There is a problem with a code, it decreases value by one second for each full timeout period. https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D208882 ^^^ Here's where I got those tunables. My kernel configuration is rather minimal and is very close to MINIMAL. Removing geom_mirror fixes the problem. Starting geom_mirror later works without any issues. Machine has UFS boot due to rather nasty Cisco firmware that only allows one single device to be available during boot. --=20 You are receiving this mail because: You are the assignee for the bug.=
