Hi folks, I did a little testing with the persistent write-back cache (*1) we run ceph quincy 17.2.1 qemu 6.2.0 rbd.fio works with the cache, but as soon as we start we get something like error: internal error: process exited while connecting to monitor: Failed to open module: /usr/lib/x86_64-linux-gnu/qemu/block-rbd.so: undefined symbol: aio_bh_schedule_oneshot_full 2022-06-30T13:08:39.640532Z qemu-system-x86_64: -blockdev so my assumption is that we need to do a bit more to have it running with qemu, if you have some more information on how to get it running please let me know! Thanks a lot, Ansgar (*1) https://docs.ceph.com/en/pacific/rbd/rbd-persistent-write-back-cache/#rbd-persistent-write-back-cache _______________________________________________ ceph-users mailing list -- ceph-users@xxxxxxx To unsubscribe send an email to ceph-users-leave@xxxxxxx
