--- Comment #9 from Peter Wemm <peter@FreeBSD.org> ---
"dedup: DDT entries 1415219, size 2676 on disk, 540 in core"
-> 728MB of ram to cache this. Fortunately that's a relatively small portion
of your system ram.
I would still be doing a zfs set dedup=off anywhere it's on. While it won't
fix the on-disk dedup corruption, at least you won't risk adding to it any
more.
Your system is crashing trying to parse the on-disk dedup records. That's what
the *_ddt_* functions are about in the traces. I can't imagine this ending
well.
Does a scrub find the problem? or does the scrub trigger the assertions?

Rebuilding ports -- no more assertions on a non-modified kernel.
Thanks Peter Wemm for the input on dedup.
I think we can close this one out.

Looks like an OLD dedup corruption/mis-feature -- rebuilding the entire system
from scratch cleaned it up.

Hello,
I have a disk with ZFS which always writes something every
'vfs.zfs.txg.timeout' seconds. By default that is 5 seconds. If I make it
30 I see writing in gstat every 30 seconds.
I only do a backup by zfs send | zfs recv hourly on this disk. So I don't
understand why it still writes something every 5 seconds while I am not
doing anything to this disk.
How can I debug what is being written every 5 seconds?
Some info:
I am running FreeBSD 10-STABLE. The disk is an external disk connected by
USB.
ugen3.2: <Philips> at usbus3
umass0: <Philips SPE3030CC, class 0/0, rev 2.00/0.00, addr 2> on usbus3
umass0: SCSI over Bulk-Only; quirks = 0x4100
umass0:4:0:-1: Attached to scbus4
da0 at umass-sim0 bus 0 scbus4 target 0 lun 0
da0: <Hitachi HDT725032VLAT80 V54O> Fixed Direct Access SCSI-0 device
da0: 40.000MB/s transfers
da0: 305245MB (625142448 512 byte sectors: 255H 63S/T 38913C)
da0: quirks=0x2<NO_6_BYTE>
Occasionally I have a message like this, but it does not seem to hurt
anything, so it is probably unrelated.
# bzgrep da0 /var/log/messages*
/var/log/messages.0.bz2:Sep 2 16:49:45 sjakie kernel:

I just created a zpool on da0 so there is no partition table.

the documentation for using the fuse library seems a bit light..
I want to stop a fuse filesystem from getting cached by the buffer cache.
(the data is dynamic)
mount_fuse(8) says I need to add the direct-io mount option,
but the mount is being done by the library call fuse_mount().
I've been hunting around for examples of how to use this argument
when using the library call.
the code curently looks like:
[...]
char *mp = arg; /* mountpoint */
struct fuse_args *farg = NULL;
#ifdef DP_DEBUG
/* enable fuse debugging */
struct fuse_args fa;
char *argv[3];
argv[0] = "dp";
argv[1] = "-d";
argv[2] = NULL;
fa.argc = 2;
fa.argv = argv;
fa.allocated = FALSE;
farg = &fa;
#endif /* DP_PROC_DEBUG */
/* unmount root (if stale) */
dp_proc_unmount(mp);
/* record load time */
dp_proc_create_time = time(NULL);
/* mount fuse filesystem */
fc = fuse_mount(mp, farg);
if (!fc) {
printk("%s: fuse_mount() failed\n", __FUNCTION__);
ASSERT(!"fuse_mount failed");
return -1;
}
======
dp -d seems to be the arguments to the daemon supplying data.
So I'm not really seeing a place to add "-o direct-io"
Our current work-around is to simply hack the fuse kernel module to just
disable the calls to the buffer cache. I'd rather 'turn it off' than
hack it off.
documetation of this library seems really thin on the ground. As are
examples.
any help appreciated.

Greetings,
So this is odd. I followed the instructions at
http://www.bsdnow.tv/tutorials/pefs
on one system, and as a regular user it works fine.
But I try it on my laptop, and I get the following:
rcarter@knuth> kldstat -m pefs
Id Refs Name
27 1 pefs
rcarter@knuth> mkdir ~/docs
rcarter@knuth> pefs addchain -f -Z ~/docs
Enter parent key passphrase:
Reenter parent key passphrase:
rcarter@knuth> pefs mount ~/docs ~/docs
pefs mount: /home/rcarter/docs: Operation not permitted
rcarter@knuth> sudo pefs mount ~/docs ~/docs
rcarter@knuth> pefs unmount ~/docs
pefs unmount: unmount of /usr/home/rcarter/docs failed: Operation not
permitted
rcarter@knuth> sudo pefs unmount ~/docs
rcarter@knuth> /bin/rm -rf ~/docs
rcarter@knuth>
So it works as root but not as $USER. I don't see anything different
about /etc/group on either system.
Any ideas?
Thanks,
Russell
