Subject: Lazytime undone by/not working with remount?
Hi,
playing with lazytime on 4.0.4-rc1 + yesterday's fencepost patch) I noticed
something odd. Mounting secondary (non-root) partitions with lazytime works
fine, but / does not seem to retain the value from fstab - apparently because
it is remounted rw during boot, and lazytime gets swallowed/undone.
Same effect when trying to remount manually with lazytime:
tux>findmnt /
TARGET SOURCE FSTYPE OPTIONS
/ /dev/sda1 ext4 rw,noatime
tux>mount -o lazytime,remount /
tux>dmesg
[ 5208.482505] EXT4-fs (sda1): re-mounted. Opts: (null)
tux>findmnt /
TARGET SOURCE FSTYPE OPTIONS
/ /dev/sda1 ext4 rw,noatime
tux>mount --version
mount from util-linux 2.26.2 (libmount 2.26.0: assert, debug)
Newly mounting unmounted partitions works fine.
Any ideas?
Holger
