I'm having trouble reproducing this on a Bionic nspawn container on arm64; what host release, and container release, are you using? Are you using the latest glibc and systemd?

The former is apparently not used, and glibc calls the latter whenever a userspace program calls sync_file_range. I'm guessing systemd-nspawn doesn't know this, because the follow code consistently fails in an nspawn container on ARM: #define _GNU_SOURCE #include <fcntl.h> #include <unistd.h> #include <stdio.h> #include <errno.h> void main() { int f = open("/tmp/syncrange.test",O_CREAT|O_RDWR,0666); int r=sync_file_range(f, 0, 0, 0); if (r) perror("sync_file_range"); close(f); } This seems to be causing problems specifically for borg(backup) and postgres: https://github.com/borgbackup/borg/issues/4710 https://www.postgresql.org/message-id/flat/CA%2BhUKG%2BydOUT4zjxb6QmJWy8U9WbC-q%2BJWV7wLsEY9Df%3Dmw0Mw%40mail.gmail.com#ac8f14897647dc7eae3c7e7cbed36d93 The solution should be to cherrypick https://github.com/systemd/systemd/pull/13352, I am currently waiting for systemd to rebuild on a slow ARM box. Any chance of an SRU?
