I'm guessing this is your root fs? xfs today will silently ignore unknown mount options on remount (patches to fix that are upstream), and the root fs may get remounted w/ fstab options. So presumably that's how you got lazytime into the mount output, especially if it's looking at /etc/mtab. Look in /proc/mounts; I doubt you'll see "lazytime" for this filesystem: [root ~]# mount /dev/sdb1 /mnt/test [root ~]# mount -o remount,lazytime /mnt/test [root ~]# grep sdb1 /etc/mtab /proc/mounts /etc/mtab:/dev/sdb1 /mnt/test xfs rw,lazytime 0 0 /proc/mounts:/dev/sdb1 /mnt/test xfs rw,seclabel,relatime,attr2,inode64,noquota 0 0 -Eric _______________________________________________ xfs mailing list xfs@oss.sgi.com http://oss.sgi.com/mailman/listinfo/xfs
