The device tree for your 250 might be different, so you may need to
hack the path_to_inst and /devices and /dev to make it boot sucessfully.

Hi,
I'm using 6 SATA ports from the motherboard but I've now run out of SATA ports,
and so I'm thinking of adding a Supermicro AOC-SAT2-MV8 8-port SATA controller
card.
What is the procedure for migrating the drives to this card?
Is it a simple case of (1) issuing a 'zpool export pool_name' com
Hi,
I have a ZFS storage pool consisting of a single RAIDZ2 vdev of 6 drives, and I

The Dell SAS controller probably have on-board write cache which helps with

Based on my limited understanding, the 7110 does not have write cache on SAS

That's a good question if it's meant genuinely, and not to be
obstructionist. It's hard to report one bug with clear information
because the problem isn't well-isolated yet.

I've got a Thumper running snv_57 and a large ZFS pool. I recently noticed a

no, it isn't. Not all the bugs are visible, and after submitting a
bug it has to be approved. Neither is true of the mailing list.

Kees,
is it possible to get at least the contents of /export/home ?
that is supposedly a separate file system. is there a way to look for files
using some low level disk reading tool. If you are old enough to remember the
80s there was stuff like PCTools that could read anywhere on the disk. I
Generally, yes. Test it with your workload and see how it works out for you.

Hi all.
Because the property compression could decrease the file size, and the file IO
will be decreased also.
So, would it increase the ZFS I/O throughput with compression?
for example:
I turn on gzip-9，on a server with 2*4core Xeon, 8GB RAM.
It could compress my files with compressratio 2.5x+

So how are folks getting around the NFS speed hit? Using SSD or battery backed
RAM ZILs?
Regarding limited NFS mounts, underneath a single NFS mount, would it work to:
* Create a new VM
* Remove the VM from inventory
* Create a new ZFS file system underneath the original
* Copy the VM to that fi
