Hi Ted, Whilst we were at Vault, I asked you if there was any live ext4 information that it could be useful to export through fsinfo(). I've implemented a patch that exports six superblock timestamps: FSINFO_ATTR_EXT4_TIMESTAMPS: mkfs : 2016-02-26 00:37:03 mount : 2020-03-31 21:57:30 write : 2020-03-31 21:57:28 fsck : 2018-12-17 23:32:45 1st-err : - last-err: - but is there anything else that could be of interest? Thanks, David
