OCI – Problem with glibc libraries - relocation error

Applies to:

Oracle Cloud Infrastructure - Version N/A and later

Linux x86-64

Symptoms

$ sudo ls -ltr /lib64l/ibc.so.6*
ls: relocation error: /lib64/libc.so.6: symbol _dl_audit_symbind_alt, version GLIBC_PRIVATE not defined in file ld-linux-x86-64.so.2 with link time reference

Cause

The instance is running Oracle Linux 7, and the "libc.so.6" was copied from an Oracle Linux 8 system and replaced a specific library file in the Oracle Linux 7 system.

Solution

An attempt to boot from single user mode failed because the instance crashed before jumping the bash prompt in Single User Mode.

To recover the instance, the boot volume will need to be detached and attached to a temporary instance running the same version as the "faulted" instance.
