Fixing txg commit frequency
Hi All,
I''d like to ask about whether there is a method to enforce a certain txg
commit frequency on ZFS. I''m doing a large amount of video streaming
from a storage pool while also slowly continuously writing a constant
volume of data to it (using a normal file descriptor, *not* in O_SYNC).
When reading volume goes over a certain threshold (and average pool load
over ~50%), ZFS

Single-disk rpool with inconsistent checksums, import fails
...tried preparing the system tunables as well:
:; echo "aok/W 1" | mdb -kw
:; echo "zfs_recover/W 1" | mdb -kw
and sometimes adding:
:; echo zfs_vdev_max_pending/W0t5 | mdb -kw
:; echo zfs_resilver_delay/W0t0 | mdb -kw
:; echo zfs_resilver_min_time_ms/W0t20000 | mdb -kw
:; echo zfs_txg_synctime/W0t1 | mdb -kw
In this case I am not very hesitant to recreate the rpool
and reinstall the OS - it was mostly needed to server the
separate data pool. However this option is not always an
acceptable one, so I wonder if anything can be done to
repair an inconsistent non-redundant pool - at least...
