You need to re-run autogen.sh, configure, then rebuild the Lustre modules against the version of ZFS installed on the node.

Re: [lustre-discuss] Upgraded Lustre client now has SElinux failure
Hi Kevin We've hit the same issue, and reported it up to Whamcloud support. It's being actively worked on. The public LU and patch is being tracked on LU-13742 (https://jira.whamcloud.com/browse/LU-13742). Initially we bypassed the issue by setting SELinux to explicitly disabled to get the client mount working on a particular host. The mount fails if SELinux is set to permissive or targeted. This approach may or may not be appropriate for your environment of course :D Regards, Daniel. -- Daniel Rodwell Manager, Data Storage Services National Computational Infrastructure The Australian National University Canberra ACT 2601 Australia > On 5 Aug 2020, at 4:01 am, Kevin M.

[lustre-discuss] Upgraded Lustre client now has SElinux failure
Hi, I just updated a RedHat machine from RHEL8.1 to RHEL8.2, and Lustre from 2.12.4 to 2.12.5. I've built the lustre client from source, using Mellanox OFED 5.0-2.1.8.0. After the update, I can no longer mount my Lustre filesystem- I'm getting the following error: # mount /lustre [ 1482.866631] Lustre: Mounted scratch-client [ 1482.882120] SELinux: (dev lustre, type lustre) has no security xattr handler [ 1483.048469] Lustre: Unmounted scratch-client Has anyone else seen this issue?

[lustre-discuss] Can not mount ZFS-based device
Hi, I can not mount a ZFS-based device when install the lustre servers. Information in syslog is, # kernel:osd_zfs: Unknown symbol zfs_refcount_add (0) # kernel:LustreError:158-c: Can't load module 'osd-zfs' And the message when insmod osd_zfs.ko manually is: # kernel:osd_zfs: Unknown symbol zfs_refcount_add (0) System information: distribution name | centos 7.6 Linux kernel | 3.10.0-957.27.2_el7 Architecture | x86_64 Lustre version | 2.12.5 ZFS version | 0.8.1 What should i do for this situation? Sincerely thanks! ___ lustre-discuss mailing list lustre-discuss@lists.lustre.org http://lists.lustre.org/listinfo.cgi/lustre-discuss-lustre.org

Andreas, I was in contact which Chris Coffey and was able to verify that he got the systemd scripts working. It seems one of the key parts was also adding a lustre-client service to ensure lustre was mounted/unmounted in the right order. I will try to get a patch submitted this week for the lnet service script. —Rick ___ lustre-discuss mailing list lustre-discuss@lists.lustre.org http://lists.lustre.org/listinfo.cgi/lustre-discuss-lustre.org
