Subject: Question about power fail during file upgrade
Date: Thu, 26 Sep 2002 04:38:47 -0400 [thread overview]
Message-ID: <19E00413.60CCAB38.0265FBE9@netscape.net> (raw)
Hi,
I need some help to understand how the JFFS2 works. If I have a version 1 of software component A on JFFS2, what happen if power failed while I am in the middle of upgrading the component A to version 2 ? The question is do I have version 1 intact or a combination of version 1 and 2 ?
Does the JFFS2 filesystem only set the inodes of a file to be valid only after a complete file is written to the flash ?
Does the old file will only be deleted only after the new file is verified to be valid ?
Thanks in advanced.
regards
choo
