Hallo,

for example, i get this error:


rpm -ivh kmod-lustre-osd-ldiskfs-2.15.5-1.el8.x86_64.rpm
error: Failed dependencies:

    kernel(jbd2_journal_clear_features) = 0xce987084 is needed by kmod-lustre-osd-ldiskfs-2.15.5-1.el8.x86_64

It could be a kernel version incompatibility issue...but i am using the RHEL 4.18.0-553.5.1.el8_10.x86_64

Hallo all,


I was able to reach this point:

i have mounted the modules for lustre...(also is it okay if the modules are in weak-updates)


[###### ~]$ sudo modprobe -v lustre
insmod /lib/modules/4.18.0-553.5.1.el8_10.x86_64/weak-updates/lustre/net/libcfs.ko
insmod /lib/modules/4.18.0-553.5.1.el8_10.x86_64/weak-updates/lustre/net/lnet.ko networks="o2ib3(ib0)"

insmod /lib/modules/4.18.0-553.5.1.el8_10.x86_64/weak-updates/lustre/fs/fld.ko
insmod /lib/modules/4.18.0-553.5.1.el8_10.x86_64/weak-updates/lustre/fs/fid.ko
insmod /lib/modules/4.18.0-553.5.1.el8_10.x86_64/weak-updates/lustre/fs/osc.ko
insmod /lib/modules/4.18.0-553.5.1.el8_10.x86_64/weak-updates/lustre/fs/lov.ko

insmod /lib/modules/4.18.0-553.5.1.el8_10.x86_64/weak-updates/lustre/fs/lustre.ko

but i cannot mount for ldiskfs:

[####### ~]$ sudo modprobe -v ldiskfs
modprobe: FATAL: Module ldiskfs not found in directory /lib/modules/4.18.0-553.5.1.el8_10.x86_64

I understand i do not have the correct ldiskfs rpm:

[###### ~]$ sudo dnf list installed | grep lustre

kmod-lustre.x86_64                          2.15.5-1.el8                              @@System
lustre-osd-ldiskfs-mount.x86_64             2.15.5-1.el8                              @@System

Could you please tell me, which rpm should i use from whamcloud, to correctly install ldiskfs.
This is the whamcloud repo: https://build.whamcloud.com/job/lustre-b2_15/94/arch=x86_64,build_type=server,distro=el8.10,ib_stack=inkernel/artifact/artifacts/RPMS/x86_64/

You have a mismatched version
But the error was clear it needs the version shown in the error that is all

You have installed and  E2 fsprogs different

Just to clarify things a bit more, if you look at what is provided by the standard RHEL e2fsprogs package, you get something like this:

#> rpm -q --provides e2fsprogs
config(e2fsprogs) = 1.46.5-5.el9
e2fsprogs = 1.46.5-5.el9
e2fsprogs(x86-64) = 1.46.5-5.el9
e4fsprogs = 1.46.5-5.el9

But if you do the same for the lustre-patched version of e2fsprogs, you get this:

#> rpm -q --provides e2fsprogs
config(e2fsprogs) = 1.46.5.cr1.8-1.el8
e2fsprogs = 1.46.5.cr1.8-1.el8
e2fsprogs(x86-64) = 1.46.5.cr1.8-1.el8
e4fsprogs = 1.46.5.cr1.8-1.el8
ldiskfsprogs = 1.46.5.cr1.8

This is why the lustre-osd-ldiskfs-mount package has a requirement for ldiskfsprogs and not just e2fsprogs.  It is trying to ensure that the installed version of e2fsprogs on the system has any needed lustre patches.

Hallo 😊,
I need another help in understanding this issue.
I am trying to install lustre 2.15.5 on 4.18.0-553.5.1.el8_10.x86_64...and when i am trying to install the rpm binary "lustre-osd-ldiskfs-mount", i get the following error..


[######~]$ sudo rpm -i lustre-osd-ldiskfs-mount-2.15.5-1.el8.x86_64.rpm
error: Failed dependencies:
ldiskfsprogs >= 1.45.6.wc1 is needed by lustre-osd-ldiskfs-mount-2.15.5-1.el8.x86_64

Please note, i already have e2fsprogs on my machine....which is what ldiskfsprogs is called after 1.45.6

[###### ~]$ sudo dnf list installed | grep e2fsprogs
e2fsprogs.x86_64 1.45.6-7.el8_10 @anaconda
e2fsprogs-devel.x86_64 1.45.6-7.el8_10 @gsi-rocky-base
e2fsprogs-libs.x86_64 1.45.6-7.el8_10 @anaconda

Please let me know what my mistake here is....
I have already installed lustre-ldiskfs-dkms-2.15.5-1.el8.noarch.rpm

MfG
Abhilasha

I guess you need to explain whether you are trying to install the binary RPM modules (Lustre 2.15.5 RPM packages are available for 4.18.0-553.5.1 at
https://build.whamcloud.com/job/lustre-b2_15/94/arch=x86_64,build_type=server,distro=el8.10,ib_stack=inkernel/artifact/artifacts/RPMS/x86_64/ <https://build.whamcloud.com/job/lustre-b2_15/94/arch=x86_64,build_type=server,distro=el8.10,ib_stack=inkernel/artifact/artifacts/RPMS/x86_64/> <https://urldefense.us/v2/url?u=https-3A__build.whamcloud.com_job_lustre-2Db2-5F15_94_arch-3Dx86-5F64-2Cbuild-5Ftype-3Dserver-2Cdistro-3Del8.10-2Cib-5Fstack-3Dinkernel_artifact_artifacts_RPMS_x86-5F64_&d=DwMGaQ&c=v4IIwRuZAmwupIjowmMWUmLasxPEgYsgNI-O7C4ViYc&r=SpEwA4Pnyq7nH7aMGq8KpA&m=jEYBshGHHqRQKLtZ18b8GCMqu6Gpms6toj6gWEjIusqR3VMLZeYGgdyhdPUvdUaF&s=M-BQDbZkp6zOa9LBDk6HcN-8_cD_o2JqQvAi-2ml0tM&e=> <https://urldefense.us/v2/url?u=https-3A__build.whamcloud.com_job_lustre-2Db2-5F15_94_arch-3Dx86-5F64-2Cbuild-5Ftype-3Dserver-2Cdistro-3Del8.10-2Cib-5Fstack-3Dinkernel_artifact_artifacts_RPMS_x86-5F64_&amp;d=DwMGaQ&amp;c=v4IIwRuZAmwupIjowmMWUmLasxPEgYsgNI-O7C4ViYc&amp;r=SpEwA4Pnyq7nH7aMGq8KpA&amp;m=jEYBshGHHqRQKLtZ18b8GCMqu6Gpms6toj6gWEjIusqR3VMLZeYGgdyhdPUvdUaF&amp;s=M-BQDbZkp6zOa9LBDk6HcN-8_cD_o2JqQvAi-2ml0tM&amp;e=>>)
or if you are trying to build your own packages using DKMS?


Installing the binary RPMs is *much* easier, in which case you don't need
the DKMS packages at all.


If you are building your own packages then you should use 2.15.8 since it
contains a lot more fixes than installing 2.15.5 on a new system.


Cheers, Andreas
