Looking at the first link he clearly states that ZIL is written to in a round
robin fashion, I was under the impression that 2 log devices would then be
faster than 1…unless mirrored of course.
If this is not true, what is the point of allowing more than 1 vdev as log
device at all?
How can I
Hello,
OmniOS v11 r151010
Can somebody help determine the cause of the growth of the file to this
size 1.6P?
Without reasons happened increasing file to unbelievably large size
This is qcow2 image of the virtual machine. The KVM hypervisor.
I copied normal file from a snapshot, but a few day

This could be a mistaken impression. The slog commits
Well that sucks... I guess one more reason to move to NV-Dimms to replace slow
SLC cards.

Is there a way to stripe two block devices and use them as log?
I tried following this one
https://blogs.oracle.com/bilke/entry/raid_0_stripe_on_solaris
But I cannot use the device in ZFS - getting the following error: cannot use
'/dev/md/rdsk/zil1d0': must be a block device or regular file
Br,
I get only about half the bandwidth with Sync=Always compared to Sync=Disabled.
Using an SLC device that should perform better, its rated as 750 MB/sec, I only
get something like 60% of that at best of times. If there is a way to stripe a
ZIL it would be great. I have enough to mirror two stripe
