It took a little while since it's a 2.4TiB filesystem. Here is the last line of the "-v debug" restore (path names scrubbed for anonymity): xfsrestore: restoring UNIX domain socket ino 128004852 backup/secondary/backups/firefly/root/backups/[...]/etc/socket Segmentation fault (core dumped) [root@betelgeuse ~]# dmesg | tail -n 1 xfsrestore[18838]: segfault at 10 ip 00000033fd8478de sp 00007fcad10a0e00 error 4 in libc-2.12.so[33fd800000+189000] So it appears that a socket is causing the problem.
