The jdata flag causes all the data written to a file to be journaled. If the jdata flag is set for a directory, all files and directories subsequently created within that directory are also journaled. This behavior replaces the old inherit_jdata flag from gfs. Same as chattr +j.
The immutable flag marks the file immutable. The behavior is similar to the immutable flag in the ext2/3 filesystems. All write access is denied. Same as chattr +i.
The appendonly flag causes all data to be written at the end of the file. Same as chattr +a.
The noatime flag disables updates to the file's access time. Same as chattr +A.
The sync flag causes data written to the file to be sync'ed to stable storage immediately. Same as chattr +S.
