The free block count in the superblock is not kept up to date while the filesystem is mounted, so this is a very common situation. Also, there is absolutely no information here about what happened to the filesystem before e2fsck was run, so there isn't really anything useful that can be done here. </p> <p>e2fsck logs, kern and messages are uploaded to FTP.<br/> ftp.whamcloud.com: /uploads/LU15265</p> <p>I hope /var/log/messages and /var/log/kern is pretty enough to know what happened prior to the e2fsck test.
