Subject: How to organize UBI volumes and power crash
Date: Tue, 02 Oct 2018 10:42:31 +0300	[thread overview]
Message-ID: <5BB32167.1040902@ircoc.vrn.ru> (raw)

I use UBIFS at my device. I'd like 2 UBIFS volumes, first volume for 
work purposes, and second volume for logs omly. RootFS is in RAM.

Both volumes are R/W, but the first volume is not intended for permanent 
writing. The second volume is intended for permanent writing (logs and 
some data tables).

The second volume may be failured in casual power crash. But the first 
volume would work.

Will it be safe to have only 1 mfd device, and 2 UBI volume on the mtd 
device? Or I must to have 2 separate mtd devices with one UBI volume on 
each? The second approach is not suitable because of device tree 
modifications when I want to change volume sizes/
