hi
I am currently running a linux box as my fileserver at home.
It's got eight 250 gig sata2 drives connected to two sata pci controllers and
configured as one big raid5 with linux software raid.
Linux is (and solaris will be) installed on two separate mirrored disks.

We are using zfs compression across 5 zpools, about 45TB of data on
iSCSI storage. I/O is very fast, with small fractional CPU usage (seat
of the pants metrics here, sorry). We have one other large 10TB volume
for nearline Networker backups, and that one isn't compressed. We

Let's say, if it were possible to detect the remote compression support,
couldn't we send it compressed? With higher compression rates, wouldn't

In pre-ZFS era, we had observable parameters like scan rate and anonymous
page-in/-out counters to discover situations when a system experiences a lack
of physical memory. With ZFS, it's difficult to use mentioned parameters to
figure out situations like that. Has someone any idea what we can us

I was presenting to a customer at the EBC yesterday, and one of the
people at the meeting said using df in ZFS really drives him crazy (no,
that's all the detail I have). Any ideas/suggestions?

I suspect that this is related to the notion
Apparently with zfs boot, if the zpool is a version grub doesn't
recognize, it merely ignores any zfs entries in menu.lst, and
apparently instead boots the first entry it thinks it can boot. I ran
into this myself due to some boneheaded mistakes while doing a very
manual zfs / install at the summi
Hey Guys,
Its not possible yet to fracture a snapshot or clone into a
self-standing filesystem is it? Basically, I'd like to fracture a
snapshot/clone into is own FS so I can rollback past that snapshot in
the original filesystem and still keep that data.
Thank you in advance.
Best Regards,
Jaso

Hey all -
Time for my silly question of the day, and before I bust out vi and

If there a simple, existing way I can observe the read / write / IOPS on
a per-zvol basis?
If not, is there interest in having one?
Cheers!
