[gpfsug-discuss] depmod: ERROR: fstatat(4, mmfs26.ko): No such file or directory

[Wei Guo]

Hi, All,

We are testing to upgrade our clients to new RHEL 7.3 kernel with GPFS 4.2.1.0. When we have 3.10.0-514.26.2.el7, installing the gplbin has the following errors:

# ./mmbuildgpl --build-package -v

# cd /root/rpmbuild/RPMS/x86_64/

# rpm -ivh gpfs.gplbin-3.10.0-514.26.2.el7.x86_64-4.2.1-0.x86_64.rpm
Running transaction
  Installing : gpfs.gplbin-3.10.0-514.26.2.el7.x86_64-4.2.1-0.x86_64        1/1
depmod: ERROR: fstatat(4, mmfs26.ko): No such file or directory
depmod: ERROR: fstatat(4, mmfslinux.ko): No such file or directory
depmod: ERROR: fstatat(4, tracedev.ko): No such file or directory


depmod -a also show the three kernel extension not found.

However, in the following directory, they are there.
# pwd
/lib/modules/3.10.0-514.26.2.el7.x86_64/extra

# ls
kernel  mmfs26.ko  mmfslinux.ko  tracedev.ko

The error does not show in a slightly older kernel -3.10.0-514.21.2 version. From https://www.ibm.com/support/knowledgecenter/en/STXKQY/gpfsclustersfaq.html Table 29<https://www.ibm.com/support/knowledgecenter/en/STXKQY/gpfsclustersfaq.html%20Table%2029>, both versions should be supported.

For technical reasons, this test node will not be added to production. A previous thread  http://www.spectrumscale.org/pipermail/gpfsug-discuss/2016-April/001529.html  indicated that this will be OK. However, it is better to get a clear conclusion before we update other client nodes. Shall we recompile the kernel? Thanks all.
