Then rebooted and updated spl and zfs. In the past this has worked. The new kernel is 2.6.32-573.22.1.el6.x86_64. \r\n\r\nI tried completely removing zfs, spl, zfs-dkms, spl-dkms and verified with \"dkms status\" that there was nothing there. Then I did \"yum install zfs\" and it installed them all again. However, when got done it still says it can't find zfs.ko when I run \"modprobe zfs\". \r\n\r\ndkms status shows:\r\n\r\n> [root@nfs4 ~]# dkms status\r\n> Error! Could not locate dkms.conf file.\r\n> File:  does not exist.\r\n> spl, 0.6.5.6, 2.6.32-504.23.4.el6.x86_64, x86_64: installed-weak from 2.6.32-573.22.1.el6.x86_64\r\n> zfs, 0.6.5.6, 2.6.32-504.23.4.el6.x86_64, x86_64: installed-weak from 2.6.32-573.22.1.el6.x86_64\r\n> spl, 0.6.5.6, 2.6.32-504.el6.x86_64, x86_64: installed-weak from 2.6.32-573.22.1.el6.x86_64\r\n> zfs, 0.6.5.6, 2.6.32-504.el6.x86_64, x86_64: installed-weak from 2.6.32-573.22.1.el6.x86_64\r\n> spl, 0.6.5.6, 2.6.32-573.18.1.el6.x86_64, x86_64: installed-weak from 2.6.32-573.22.1.el6.x86_64\r\n> zfs, 0.6.5.6, 2.6.32-573.18.1.el6.x86_64, x86_64: installed-weak from 2.6.32-573.22.1.el6.x86_64\r\n\r\nSo, indeed, there is no zfs/spl for the current kernel for some reason. I will attach the output of the yum install command. I tried booting into the previous kernel and it didn't find zfs.ko either. possibly because of what it says at the end: installed-weak from 2.6.32-573.22.1.el6-x86_64?\r\n\r\nIf I try to do \"dkms install spl\" it says:\r\n\r\n> Module zfs/0.6.5.6 already installed on kernel 2.6.32-573.22.1.el6.x86_64/x86_64\r\n\r\nI'll try going to the previous kernel, uninstalling it all and then installing it again. \r\n\r\n"}}
