Refactor zfs_zget()
Hi,
Since almost all operations in the FUSE low-level API identify files by inode
number, I''ve been using zfs_zget() to get the corresponding znode/vnode in
order to call the corresponding VFS function in zfs_vnops.c.
However, there are some cases when zfs_zget() behaves slightly different than
I need:
1) If zp->z_unlinked != 0 then zfs_zget() returns ENOENT. I need it to return

Improper use of atomic_add_64().
Hi.
I noticed that when non-64bit variable is given as a second argument to
atomic_add_64() function, the result is invalid.
I found few places where such situation occurs. I wonder how this got
unnoticed with ztest, which fails on me within a few seconds (after I
started to use Solaris atomic operations) on assertions. Maybe this
only doesn''t work when compiled with gcc? Not sure, but

Preparing to compare Solaris/ZFS and FreeBSD/ZFS performance.
Hi.
I''m all set for doing performance comparsion between Solaris/ZFS and
FreeBSD/ZFS. I spend last few weeks on FreeBSD/ZFS optimizations and I
think I''m ready. The machine is 1xQuad-core DELL PowerEdge 1950, 2GB
RAM, 15 x 74GB-FC-10K accesses via 2x2Gbit FC links. Unfortunately the
links to disks are the bottleneck, so I''m going to use not more than 4
disks, probably.

Centos6 Migration glitch - ZFS-FUSE
Folks
My experiments with installing ZFS-FUSE in a Centos 6 system reveal
behavior different from that observed in Centos 5.6.
The version of ZFS-FUSE is that provided on the EPEL repository, and
was installed on a 32-bit machine. I use it because of its
deduplication facility.
In Centos 5.6, the facility worked as advertised.
In Centos 6, however, the system "hung" in

Help:Is zfs-fuse''s performance is not good
I wonder if this is the right place to ask, as the Filesystem in User Space implementation is a separate project. In Solaris ZFS runs in kernel. FUSE implementations are slow, no doubt. Same goes for other FUSE implementations, such as for NTFS.
Regards,
Tonmaus

libguestfs and zfs-fuse
I'm wondering whether or not anyone has tried to use guestmount on an
image with a ZFS partition (MBR partition table). I can't seem to find
much on the internet regarding it, but I do see hints that may lead me
to a solution. I'm under the impression that libguestfs can use what
ever is available to the kernel on the host -- in my case I have zfs-use
installed and running. I

X86 does not follow -fuse-init-array
Hi Devs,
consider below testcases,
$cat test.cc
class B {
public:
B(int t) {
j=t;
}
int j;
};
B b(1);
==============
$clang test.cc -target -i386 -c -fuse-init-array
$llvm-objdump -h test.o |grep ctors
7 .ctors 00000004 00000000 DATA
8 .rel.ctors 00000008 00000000
As you can see it ignores the -fuse-init-array options.It happens for
x86,Other target like aarch64 is doing fine.

Files are duplicated after renaming (with glusterfs+zfs-fuse)
Hi all,
I installed glusterfs (version 3.1.3) with zfs-fuse (0.6.9) as the
underlying filesystem.
After renaming a file, I found the file duplicated.
Following is my test scenario.
root at ubuntu:/# zpool create tank /dev/sdb
root at ubuntu:/# gluster volume create test-volume ubuntu:/tank/exp1
ubuntu:/exp2
root at ubuntu:/# gluster volume start test-volume
root at ubuntu:/# mount -t glusterfs

ZFS for Linux?
Hello,
A college friend of mine is using Debian Linux on his desktop,
and wondered if he could tap into ZFS goodness without adding
another server in his small quiet apartment or changing the
desktop OS. According to his research, there are some kernel
modules for Debian which implement ZFS, or a FUSE variant.
Can anyone comment how stable and functional these are?

ZFS Scalability/performance
Hello,
I''m quite interested in ZFS, like everybody else I suppose, and am about
to install FBSD with ZFS.
On that note, i have a different first question to start with. I
personally am a Linux fanboy, and would love to see/use ZFS on linux. I
assume that I can use those ZFS disks later with any os that can
work/recognizes ZFS correct? e.g. I can install/setup ZFS in FBSD, and

LZO compression?
Hi,
I don''t know if this has been discussed before, but have you thought
about adding LZO compression to ZFS?
One zfs-fuse user has provided a patch which implements LZO compression,
and he claims better compression ratios *and* better speed than lzjb.
The miniLZO library is licensed under the GPL, but the author
specifically says that other licenses are available by request.

[PATCH ubuntu] ubuntu: Remove two FUSE packages from the default list.
Previously:
http://www.redhat.com/archives/libguestfs/2009-December/msg00044.html
we had to disable a lot of packages which were missing in Ubuntu Karmic.
However with the patch I just posted:
https://www.redhat.com/archives/libguestfs/2010-May/msg00132.html
we don't need to remove packages just because they are missing.
But there is still one package which is present but doesn't install

ZFS Evil Tuning Guide
Tuning should not be done in general and Best practices
should be followed.
So get very much acquainted with this first :

ZFS and memory usage.
ZFS works really stable on FreeBSD, but I''m biggest problem is how to
control ZFS memory usage. I''ve no idea how to leash that beast.
FreeBSD has a backpresure mechanism. I can register my function so it
will be called when there are memory problems, which I do. I using it
for ARC layer.
Even with this in place under heavy load the kernel panics, because
