On Dell PowerEdge R730XD servers running CentOS 7.2 when the new version of dell-system-update (Ver 1.3.1) was installed, using yum, a library symbolic link for openblas got changed and caused issues on an application running on our servers.
The link that specifically got changed is located in /usr/lib64 and appears as lrwxrwxrwx 1 root root 33 Jan 13 20:24 libblas.so.3 -> /usr/lib64/libopenblas-r0.2.18.so After DSU is installed using yum, the link is changed to: lrwxrwxrwx 1 root root 16 Feb 14 21:34 libblas.so.3 -> libblas.so.3.4.2 We believe the root cause to be a command that is part of the post install that is embedded in the rpm. The last command run is /sbin/ldconfig This command is causing the library link to change. Examining the post installation of the dell-system-update rpm it was noted that the last command run is /sbin/ldconfig As a test we reset the link to the libopenblas-r0.2.18.so and ran the /sbin/ldconfig as a standalone command. The result was that the link was changed again to point to libblas.so.3.4.2 Has anyone run into this, or does anyone have a resolution to the library being changed? Thanks for your replies, S.
