yesterday i had a strange data loss here is my configuration Freebsd 11.0p9 bhyve box (i know i should upgrade) 1x Guest with FreeBSD 10.3 file disk image (with ufs inside) 2x Guests with FreeBSD 11.1 zfs filesystems on the same zpool (mirror) like first Guest 2x Guests with FreeBSD 11.0 zfs filesystems on other zpool other mirror 128 GB RAM ... HDs are SSD Server freezes at 23:00 local time -> no login possible to bhyve box and the first guest... other guests running normal On my fault i had no access to the KVM-Console with ipmi .. so i shtudown per ipmi acpi power key After reboot the data on the first guest was reset to 16:25 local time... (no snapshots after this time) the first guest is a imap server ... i know it was working until 21:30 because a had some mail received between 19:00 to 21:30.. after reboot data is lost up to 16:24 i found the following in messages.log at the bhyve box: Jan 4 16:25:04 hv1 kernel: pid 48842 (zfs), uid 0: exited on signal 6 (core dumped) an now my question ... how can i prevent such a sick behavior?
