Booted a Centos 7 DVD (all I had on hand) and went into the rescue mode. All the disks look OK (SMART values good) and the RAID (PERC H310) filesystems all fsck OK. However, doing this:
Code: Select all
In other words, it behaves exactly like this:
but I don't have a subscription so cannot read the solution there.

Some other posts suggest that this is the phenotype a system shows after the incorrect installation of glibc for the wrong architecture.
Anyway, it is not in great shape. The boot loader seems to be intact, it gives the option of selecting from various kernels, and it lets me edit the options. But all of them segfault at the same place.
Anybody been through this before? I think the rescue disk needs to check that all of the installed RPMs are valid, but since I cannot chroot into that system, I'm not sure how to make rpm do that.
