Why does UFS (FreeBSD) crash when the computer is powered off?

Question

FreeBSD

Dimitri, please help! There is a home server (Pentium3, 512 Mb RAM) on freebsd. It is used exclusively for storing all sorts of information trash and torrents, neither of which you want to lose. I would do it on a win server, fortunately, there is a little experience, but all systems hang tightly during installation or during boot (I checked the memory and HDD), but frya does not. Well, we often turn off the light, and it’s impossible to install a good UPS (it’s physically possible, but highly undesirable). And almost every time when the power is turned off, ufs crashes and you have to reinstall the system and software, at least three times a day before meals, make backups to the cloud, magnetic tape, flash drives, CDs, gramophone records, rollers for the music box and parchment. Please advise any solution. Option "

Answer 1

there is no way out - you need a UPS
with frequent power outages, you risk killing the hard, and not just the fs.

Answer 2

Dlink, oddly enough, will save you). He has many times higher survivability during jumps!

Answer 3

All this nonsense with the use of old iron will end one day when the drive dies. FreeBSD, to my great regret, does not have a recoverable file system - softupdate brings it down with just a half-kick. I myself suffer from this - all the time there is no rearrangement of the old server on FreeBSD, which, as soon as the power is lost - softupdate inconsistency and hello fsck :)
Of course, there is an option to disable softupdate in the properties of the file. But then the truth speed of its work will fall.
If you want to try it, it's done via tunefs on an unmounted file. The root, of course, cannot be configured in this way, but yes, it’s quite difficult to enable softupdate on it :)
