I'm getting to know FreeBSD by running a 64-bit FreeBSD guest in a VirtualBox machine on my OS X Mountain Lion laptop. On occasion, when waking up from sleep, the FreeBSD virtual machine will not restart. VirtualBox marks it as "Aborted."
Maybe you should pause the guest before putting the host to sleep?
When I restart FreeBSD, I've found on a number of occasions that the `.git` directory of the project I was working on when my laptop went to sleep has become corrupted. `git` won't recognize the directory. I try to rebuild the repository with `git fsck`, but it's usually broken. My `.zsh_history` file has been corrupted at restart, which I've recovered by removing the last line which contains binary nonsense. I run a Linux guest that suffers the same abuse, but does not lose data. My question: If anyone runs FreeBSD in VirtualBox, what VirtualBox settings do you use so that UFS will work correctly and recover recent writes? I'm using UFS built by the install media. % mount /dev/ada0p2 on / (ufs, local, journaled soft-updates) devfs on /dev (devfs, local, multilabel) I'm using the disk and disk controller setup that VirtualBox suggested when when I told it I was building a FreeBSD machine. A single IDE drive on an IDE controller with "Use host I/O cache enabled." The VirtualBox documentation says that a virtual SATA controller is preferred if you choose to uncheck "Use host I/O cache enabled." http://www.virtualbox.org/manual/ch05.html#iocaching So... * How should I configure my filesystem for maximum durability, since the VirtualBox virtual drives appear to be flaky?
I think geom_journal will serve you better for this purpose. Geom journal records everything, that is data and metadata changes. I have used geom journal on my freebsd-current box and it has stood tenths of kernel panics and a few power-offs without a single failure. I haven't researched about the type of controller or other settings since it was never needed to. Occasional full fscks never revealed corruption.
