Re: [lustre-discuss] dkms-2.8.6 breaks installation of lustre-zfs-dkms-2.12.7-1.el7.noarch
thanks a lot, and thanks for the corrections.
Anyway I never use more than one dkms module built for different kernel
versions and usually I build the lustre dkms module always on the
current version of the running kernel, but yes your fixes will address
correctly the issues you mentioned and it is a more general approach.

This is my patch to make things works and build the lustre-dkms rpm
Thank you! I just ran into the exact same problem. Two comments on the
patch:
- ZFS_VERSION=$(dkms status -m zfs -k $3 -a $5 | awk -F', ' '{print $2;
exit 0}' | grep -v ': added$')
+ ZFS_VERSION=$(dkms status -m zfs | awk ' { print $1 } ' | sed -e
's/zfs\///' -e 's/,//')
This produces an incorrect result if the dkms module is already built
for multiple kernel versions. I would suggest picking the largest zfs
version for simplicity's sake:
+ ZFS_VERSION=$(dkms status -m zfs | awk ' { print $1 } ' | sed
-e 's/zfs\///' -e 's/,//' | sort -V | tail -n1)
Secondly,
+ SERVER="--enable-server $LDISKFS \
+- --with-linux=$4 --with-linux-obj=$4 \
+- --with-spl=$6/spl-${ZFS_VERSION} \
+- --with-spl-obj=$7/spl/${ZFS_VERSION}/$3/$5 \

++ --with-zfs=/usr/src/zfs-${ZFS_VERSION} \
++ --with-zfs-obj=/var/lib/dkms/zfs/${ZFS_VERSION}/$3/$5"
This fails if we're building for a newly installed kernel we haven't
rebooted to yet (or rather, any kernel version other than the one
that's currently booted). Also, we might want to keep open the
possibility of building for non-x86 that was present in the original
(though I don't now whether Luster even supports non-x86). So:
+ --with-zfs-obj=/var/lib/dkms/zfs/${ZFS_VERSION}/$3/$5"
To be honest, I don't understand why this second block of changes is
necessary at all; but I currently don't have the time to do any more
experiments..

Re: [lustre-discuss] Lustre Client on Ubuntu 20.04
Hi, Thanks for the info. Our server side will get upgraded to 2.12.7 LTS in a few months so looking for a more modern OS than redhat 6.7! Does the 2.14 client work with the 2.12.7 LTS...and even with 2.7? Many thanks, Emyr James Head of IT CRG - Centre for Genomic Regulation C/ Dr. Aiguader, 88 Edif.

The most recent kernel it's known to build for is Linux 4.4.x, and Ubuntu 20.04 is at least 5.4.x. The only version which officially has support for 20.04 is Lustre 2.14 (and the upcoming 2.15). For Ubuntu builds, the instructions here give the basic steps: https://wiki.lustre.org/Compiling_Lustre And the other sections have instructions which will help you with adding in MOFED.

[lustre-discuss] project quota way off
We have a weird problem with project quotas. We have a project contained in a specific directory. A du of that directory returns 71T. However lfs project shows only 1.8 TB used. Just to make sure everything was assigned correctly we ran lfs project -p -s -r on the directory to try to recalculate. That did not change any of the numbers. Any ideas as to why these numbers could be so different? Thanks in advance.
