There is no active development on LU-4009 ("Add ZIL support to osd-zfs")
so there is no ETA.
The only available workaround is LU-10460, which can be enabled with either
a module parameter:
options osd-zfs osd_txg_sync_delay_us=0
or at runtime via:
echo 0 > /sys/module/osd_zfs/parameters/osd_txg_sync_delay_us
This is available out-of-the box in Lustre 2.11 and Lustre 2.10.4 (when it is
released, which should be soon), or you can download and build b2_10 today.
Cheers, Andreas
