Hi, I check this morning, dm-snapshot.ko was yet included in initrd as show by lsinitrd. $ lsinitrd /boot/initramfs-3.10.0-1127.18.2.el7.x86_64.img | grep dm-snapshot.ko -rw-r--r-- 1 root root 20372 Jul 26 17:38 usr/lib/modules/3.10.0-1127.18.2.el7.x86_64/kernel/drivers/md/dm-snapshot.ko.xz I've rebuilt the image this morning (dracut -fv) with the snapshot "on" and I'll try a reboot next week (I work remotely these next days). An important thing is that during the kernel update (and initrd build for the new kernel), the snapshot was also available. $lvs LV VG Attr LSize Pool Origin Data% Meta% Move Log Cpy%Sync Convert data1lv1 data1vg owi-aos--- 75,00t snapdata data1vg swi-aos--- <2,93t data1lv1 1,23 homevol osvg -wi-ao---- 4,88g optvol osvg -wi-ao---- <97,66g rootvol osvg -wi-ao---- <32,23g swapvol osvg -wi-ao---- 7,81g tmpvol osvg -wi-ao---- <9,77g varvol osvg -wi-ao---- <9,77g Patrick Le 19/08/2020 à 18:18, Patrick Bégou a écrit : > Hi Gordon, > > my dracut package is the latest available for Centos7 (this occur just > after my "yum update" and reboot).
