1) What is the output of: rpm -qa | grep zfs
from that system after it boots? 2) How do those values get into the /etc/modprobe.d/zfs.conf file? Are they there before the node boots, or are modifying that file somehow during the boot process?

I had to do a echo 1 > /sys/module/zfs/parameters/options zfs zfs_prefetch_disable inside rc.local to have it working I am running RHEL7 with latest kernel and zfs 0.6.5.7-1 any hints ? thank you Riccardo _______________________________________________ lustre-discuss mailing list lustre-discuss@lists.lustre.org http://lists.lustre.org/listinfo.cgi/lustre-discuss-lustre.org _______________________________________________ lustre-discuss mailing list lustre-discuss@lists.lustre.org http://lists.lustre.org/listinfo.cgi/lustre-discuss-lustre.org
