When a file with the 'A' attribute set is accessed, its atime record is not modified. This avoids a certain amount of disk I/O for laptop systems.
However when I am remounting a filesystem with the
noatime mount option:
[root@localhost ~]# mount -o remount,noatime /dev/sdb1 /newfs/
creating a file in it
[root@localhost ~]# cd /newfs/ [root@localhost newfs]# touch myfile
and getting its file attributes:
[root@localhost newfs]# lsattr myfile -------------e-- myfile
A file attribute is not set despite the fact.
Is this the expected behavior?
