Dear Ted, on my laptop with ext4 fs (on SSD) I started to try the lazytime mount option using a self compiled kernel 4.0.2 on a debian system with mount version 2.26.2. Before that, I've used the noatime mount option. After restarting the system with an adapted /etc/fstab file and the kernel parameter "rootflags=lazytime", the relatime mount option was also set. I changed that by commanding "mount -o remount,strictatime /", etc. By accident, I noticed that some files had a modified ctime and mtime although they were not changed or modified. Has anybody else experienced that? Do I miss a patch? Mount options in fstab: nobarrier,lazytime,errors=remount-ro The filesystems are ext4 on a primary partition of the SSD with default mount option journal_data_writeback. I created them in Feb 2011. By the way, the command "mount -o remount,lazytime /" does not do the switch to lazytime. And thanks for your tireless work on Linux. -- Regards, jvp. -- To unsubscribe from this list: send the line "unsubscribe linux-fsdevel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
