Re: After the FreeBSD VM crash, file system in VM got rolled back to some old previous state causing data loss
I hit this unexpected problem: my host had an ungraceful shutdown while FreeBSD 9.1 STABLE was running in the VirtualBox VM. After reboot of the host and VM, local ufs file system was missing all recent updates for at least 20 hours (!!!) My question is, how is this possible? Is this related to journaled soft-updates which were enabled in VM? not possible in FreeBSD with UFS. but if you run virtualbox under linux i cannot say much... ___ freebsd-hackers@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to freebsd-hackers-unsubscr...@freebsd.org
Re: After the FreeBSD VM crash, file system in VM got rolled back to some old previous state causing data loss
Virtualbox is very aggressive about caching writes. This is how it achieves its perceived speed. I wouldn't expect to see this happen on real hardware. I might have to try this out though and see if I can reproduce it reliably. ___ freebsd-hackers@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to freebsd-hackers-unsubscr...@freebsd.org

This happened with FreeBSD guest with UFS (journaled soft-updates) and FreeBSD host. What is out of normal, it rolled back for many hours (~20).
