It is a beautiful mistake before DSM6.2.4 to make those models could use Btrfs.
Same hereAnd thats why I have auto-update turned off. Also for apps...
I may not have these models, but messages like these are scary nonetheless...
According to other dutch Synology forums: Yes .Did DSM 6.2.3 allow these NAS to have btrfs volumes? Could they be created on these NAS?
My guess is performance and marketingIn which case: what's Synology's reason for not 'supporting' btrfs on these NAS? Performance? Reliability? Marketing?
There is no hack to do this. I was helping someone with a 420j and noticed "btrfs" on his Storage Manager screenshots. I figured that Synology expanded btrfs use (although I did notice that the 420j spec sheet only mentioned ext4... but who knows whether that was outdated).Did DSM 6.2.3 allow these NAS to have btrfs volumes? Could they be created on these NAS?
Absolutely. This can be a real trust killer.What is unclear is whether btrfs is unstable on these units, or whether Synology purposely removed that capability as part of their marketing segmentation strategy. There's going to be many upset owners who have been left stranded by this bungle.
There's an easier way. Synology will access your NAS and return btrfs accessibility, so that you can back up your stuff before converting to EXT4 (confirmed by Community user).SOLUTION TO GET YOUR DATA BACK
