Hello Justus, I had to revert your commit:
“ commit f05b6bae5cbdf3c221eba05987dea7ab14e6524f Author: Samuel Thibault <samuel.thiba...@ens-lyon.org> Date: Mon Jan 15 22:00:11 2018 +0100 Revert "libdiskfs: Shutdown pagers on startup_dosync." This reverts commit 89a49ec8b3a847f3b770cff6a4a80b98b94ad7bf. There was a typo in diskfs_shutdown (FSYS_GOAWAY_FORCE || FSYS_GOAWAY_RECURSE) which was making it FSYS_GOAWAY_NOWAIT, and thus not actually syncing if there happens to be clients (it was then returning EBUSY). Fixing this into FSYS_GOAWAY_FORCE | FSYS_GOAWAY_RECURSE then makes it wait for clients (and NOWAIT is not supported), and there are very often some left, thus not syncing either. ” I don't know if the pager actually supports the operation that we want? (just crashing clients) Samuel
