UFS/FFS is well tested code and won't corrupt itself, but it lacks the checksumming to detect data corruption from unreliable hardware/firmware/drivers.

I had a power outage corrupt UFS and another indecent due to a kernel panic while debugging a WiFi driver.

I've run Linux on various filesystems for significantly longer and have never seen filesystem corruption - (excluding me not reading btrfs documentation right).

Did you have softupdates turned on?

As of this update, softupdates will be a NO-OP (and has been for a while in -CURRENT). This won't help you in the near future.

I won’t go over their history, but they’ve saved me in the past.

Here’s to hoping we get a modern FS soon!
