I'll suggest trying something completely different, like, dd if=/dev/zero
bs=1024k | pv | ssh othermachine 'cat /dev/null' ... Just to verify there
isn't something horribly wrong with your hardware (network).
In linux, run ifconfig ... You should see errors:0
Make sure each machine has
A couple of notes: we know the Pool_sata is resilvering, but we're concerned
about the performances of the other pool (Pool_sas). We also know that we're
not using jumbo frames as for some reason it makes the linux box crash. Could
that explain it all? What sort of drives are these? It

If you have a single SSD for dedicated log, that will

for you.

Hi,
what is the right way to check versions of zfs and zpool ??
I am writing piece of code which call zfs command line further. Before actually

Are we living in the past?
In the bad old days, UNIX systems spoke NFS and Windows systems spoke
CIFS. The cost of creating a file system was expensive -- slices, partitions,
etc.
With ZFS, file systems (datasets) are relatively inexpensive.
So, are we putting too many constraints into a

Regardless, nothing beats raidz3 based on computable statistics.
Well, no, not really. It all depends on the number of sets and the MTTR.
Consider the case where you have 1 set of raidz3 and 2 sets of 3-way
mirrors. The raidz3 set can only
