I have my /usr filesystem configured as a zfs filesystem, using a legacy mountpoint. I noticed that the system boots with atime updates temporarily turned off (and doesn't record file accesses in the /usr filesystem):
# df -h /usr Filesystem size used avail capacity Mounted on files/usr-b57 98G 2.1G 18G 11% /usr # zfs get atime files/usr-b57 NAME PROPERTY VALUE SOURCE files/usr-b57 atime off temporary That is, when a zfs legacy filesystem is mounted in read-only mode, and then remounted read/write, atime updates are off: # zfs create -o mountpoint=legacy files/foobar # mount -F zfs -o ro files/foobar /mnt # zfs get atime files/foobar NAME PROPERTY VALUE SOURCE files/foobar atime on default # mount -F zfs -o remount,rw files/foobar /mnt # zfs get atime files/foobar NAME PROPERTY VALUE SOURCE files/foobar atime off temporary Is this expected behaviour? It works if I remount with the "atime" option: # mount -F zfs -o remount,rw,atime files/foobar /mnt # zfs get atime files/foobar NAME PROPERTY VALUE SOURCE files/foobar atime on default This message posted from opensolaris.org _______________________________________________ zfs-discuss mailing list [email protected] http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
