In the last few days my performance has gone to hell. I'm running:

(I'll upgrade as soon as the desktop hang bug is fixed.)
The performance problems seem to be due to excessive I/O on the main
disk/pool.
The only things I've changed recent
Running zdb on my broken system, one of the things I see is the hostname.
I'm not sure why zfs needs to know about the hostname of the system it's
on, but...
The thing I did that started all my problems was I changed the hostname
of my system. Do I need to do something with zfs to tell it the new
I upgraded my machine to snv_101a_rc1 and now that machine is broken.

The problem seems to be some low level zfs files

Despite the error message, the recv does seem to work.
Is it a bug that it prints the error message, or is it a bug that i
I'm trying to figure out how to restore a filesystem using zfs recv.
Obviously there's some important concept I don't understand. I'm
using my zfsdump script to create the dumps that I'm going to restore.
Here's what I tried:
Save a "level 0" dump in d.0:
datsun# zfsdump 0 home/tckuser > d.0
zfs
I wrote a simple script to dump zfs snapshots in a similar way to
what I did with ufsdump. In particular, it supports dump levels.
This is still very crude, but I'd appreciate comments. Does what
I'm doing make sense, or do I misunderstand zfs?
Thanks.

Is there a zfs recv-like command that will list a table of contents
for what's in a stream?

I just wanted to follow up on this issue I raised a few weeks ago.
With help from several of you, I had all the information and tools
I needed to start debugging my problem. Which of course meant that
my problem disappeared!
At one point my theory was that ksh93 was updating my .history file

What's the best way to backup a zfs filesystem to tape, where the size
of the filesystem is larger than what can fit on a single tape?
ufsdump handles this quite nicely. Is there a similar backup program
for zfs? Or a general tape management program that can take data from
a stream and split it a

Because then I have to compute yesterday's date to do the incremental dump.
I don't suppose I can create symlinks to snapshots in order to give them

I recently converted my home directory to zfs on an external disk drive.
Approximately every three seconds I can hear the disk being accessed,
even if I'm doing nothing. The noise is driving me crazy!
I tried using dtrace to find out what process might be accessing the
disk. I used the iosnoop p
I've just started using zfs. I copied data from a ufs filesystem on
disk 1 to a zfs pool/filesystem on disk 2. Can I add disk 1 as a mirror
for disk 2, and then remove disk 2 from the mirror, and end up with all
the data back on disk 1 in zfs (after some amount of time, of course)?
