I would prefer that the word "Warning" is reserved for cases and operations that may actually damage data (such as reformating a filesystem). [Note: in a previous job, my employer decided that the word Warning was ONLY to be used if there was a risk of harm to a human - for example, electrical safety] Also, btrfs fi usage is something that I routinely run continuously in a window (using watch) when a remove/replace/balance operation is in progress to monitor at a glance what is happening - I don't want to waste all that space on the screen. To say nothing of the annoyance of having it shouting at me for weeks on end while **I AM TRYING TO FIX THE DAMN PROBLEM!**. I would suggest a more compact layout and factual tone. Something like: Caution: This filesystem has multiple profiles for a block group type so new block groups will have unpredictable profiles. * DATA -> [raid1c3, single] * METADATA -> [raid1, single] Use of 'btrfs balance' is recommended as soon as possible to move all blocks to a single profile for each of data and metadata.
