Hello everybody,
is there any known way to configure the point-in-time *when* the time-slider
will snapshot/rotate?
With hundreds of zfs filesystems, the daily snapshot rotation slows down a big
file server significantly, so it would be better to have the snapshots rotated
outside the usual
ZFS never does update-in-place and UFS only does update-in-place for
metadata and where the application forces update-in-place.
ufs always updates in place (it will rewrite earlier allocated locks).
The only time when it does is when the file is growing and it may move

The only way you will know of decrypting and decompressing causes a
problem in that case is if you try it on your systems. I seriously
doubt it will be unless the system is already heavily CPU bound and
your
backup window is already very tight.
That is true.
My understanding of the

I see. T1C is a monster to have if possible ;-).

Hi,
I have a query regarding the zfs rename command.
There are 5 zones and my requirement is to change the zone paths using

Even the data compressed/encrypted by ZFS will be decrypted? If it is true,

Processing the request just means flagging the blocks, though, right?
And the actual benefits only acrue if the garbage collection / block
reshuffling background tasks get a chance to run?
I think that's right. TRIM just gives hints to the garbage collector that
