Subject: ubiattach reserves too many BEBs for each volume attached
Date: Fri, 11 Feb 2022 16:23:46 +0100	[thread overview]
Message-ID: <> (raw)

If there is more than one volume on the device, ubiattach reserves 
amount of BEBs as for the whole device, each time. Small volumes can be 
covered mainly by reserved blocks on big devices.
With this the amount of BEBs is proportional to the volume size.
