There is good documentation 'out there' about how SD\SDHC Flash and Journaling works. The journal repeatedly written to a confined section of the filesystem.
Not all SD's are equal, either in the quality of the memory cells or in the quality of the wear-leveling algorithm. NOTE: these in-built wear-leveling algorithms can be incompatible with flash filesystems. Personal experience has demonstrated once it is 'burned' the whole SD becomes read-only. It should be the Users choice to enable journaling and risk SD destruction in preference to shutting down properly. I recommend filesystem check at boot should be enabled with journaling off and disabled with journaling on. PS: Being Raspberry Pi specific, I do not know why Raspbian does not use F2FS, but that does not exclude Devuan from using it. > _______________________________________________ > Dng mailing list > [email protected] > https://mailinglists.dyne.org/cgi-bin/mailman/listinfo/dng _______________________________________________ Dng mailing list [email protected] https://mailinglists.dyne.org/cgi-bin/mailman/listinfo/dng
