Good Morning,
I've encountered an issue updating lustre from 2.10.6 to 2.10.7 on my metadata system. I installed the updated RPMs using whamcloud's yum repository, but when I run modprobe -v lustre I get the following errors: insmod /lib/modules/3.10.0-957.1.3.el7_lustre.x86_64/extra/libcfs.ko.xz insmod /lib/modules/3.10.0-957.1.3.el7_lustre.x86_64/extra/lnet.ko.xz networks=o2ib0(bond0) insmod /lib/modules/3.10.0-957.1.3.el7_lustre.x86_64/extra/obdclass.ko.xz insmod /lib/modules/3.10.0-957.1.3.el7_lustre.x86_64/extra/ptlrpc.ko.xz insmod /lib/modules/3.10.0-957.1.3.el7_lustre.x86_64/extra/fld.ko.xz modprobe: ERROR: could not insert 'lustre': Invalid argument dmesg shows the following: [ 377.981515] fld: disagrees about version of symbol class_export_put [ 377.981518] fld: Unknown symbol class_export_put (err -22) [ 377.981529] fld: disagrees about version of symbol req_capsule_server_pack [ 377.981531] fld: Unknown symbol req_capsule_server_pack (err -22) [ 377.981537] fld: disagrees about version of symbol req_capsule_set_size [ 377.981538] fld: Unknown symbol req_capsule_set_size (err -22) [ 377.981542] fld: disagrees about version of symbol req_capsule_client_get [ 377.981543] fld: Unknown symbol req_capsule_client_get (err -22) [ 377.981555] fld: disagrees about version of symbol lu_env_init [ 377.981556] fld: Unknown symbol lu_env_init (err -22) [ 377.981562] fld: disagrees about version of symbol ptlrpc_queue_wait [ 377.981563] fld: Unknown symbol ptlrpc_queue_wait (err -22) [ 377.981571] fld: disagrees about version of symbol lu_context_key_get [ 377.981573] fld: Unknown symbol lu_context_key_get (err -22) [ 377.981604] fld: disagrees about version of symbol lu_env_fini [ 377.981606] fld: Unknown symbol lu_env_fini (err -22) [ 377.981611] fld: disagrees about version of symbol lu_context_key_degister [ 377.981612] fld: Unknown symbol lu_context_key_degister (err -22) [ 377.981623] fld: disagrees about version of symbol class_exp2cliimp [ 377.981625] fld: Unknown symbol class_exp2cliimp (err -22) [ 377.981631] fld: disagrees about version of symbol req_capsule_set [ 377.981632] fld: Unknown symbol req_capsule_set (err -22) I've tried uninstalling and reinstalling the RPMs but this is always the state I end up in. I'm using zfs for the back end, and those modules work after the upgrade Here are the RPMs currently installed. perf-3.10.0-957.1.3.el7_lustre.x86_64 lustre-resource-agents-2.10.7-1.el7.x86_64 lustre-osd-zfs-mount-2.10.7-1.el7.x86_64 kernel-headers-3.10.0-957.1.3.el7_lustre.x86_64 lustre-2.10.7-1.el7.x86_64 kernel-3.10.0-957.1.3.el7_lustre.x86_64 perf-debuginfo-3.10.0-957.el7_lustre.x86_64 lustre-zfs-dkms-2.10.7-1.el7.noarch kernel-debuginfo-common-x86_64-3.10.0-957.el7_lustre.x86_64 kernel-devel-3.10.0-957.1.3.el7_lustre.x86_64 bpftool-3.10.0-957.el7_lustre.x86_64 Thank you, Kurt J.
