Hello,
I have a test server were I was using zfs-fuse.
It was slow but it worked.
Now I switched to kqzfs but I have two problems:
- the first, obvious, if I import zfs-fuse pools I have the same
problems of people that try to import bsd or solaris pools (chmod
000...);
- the second, more serious is that if I try a bonnie++ benchmark (with
a new pool created with kqzfs) with size 4000 it complete the test,
with size 30000 it hangs the system (kernel oops).
I have checked system ram and it is ok. With zfs-fuse all benchmarks
are fine.
What can I do?
Thanks,
Mario

The first thing that you can do is to post here all of the informations
that you have about the error, exact text included!
At worst a screen photo is better than nothing, but only if you really
can't save the log with dmesg >logfiletoposthere.

Hi,
first problem of chmod 000.. might created because of different version of zfs-fuse and kq zfs file system.
you can upgrade the zpool and zfs to the current version after importing pool which created by zfs-fuse
e.g:
#zpool upgrade -V 28 <poolname>
#zfs upgrade -V 5 <fsname>
#zfs upgrade -V 5 <poolname>
#zfs get all <fsname> -- to check version
it might solve your first problem.

I have upgraded pool and zfs following your instructions.
Now for old files permission are maintained. New files are created
again with 000 permissions, but now I can change them and even with
permission 000 I can read and write the files.

Well, I cannot give you the stack trace of a full system hang.
Anyway I have done some tests and it seems that to complete tests you
should not have nay zfs-fuse filesystem imported.
Even if you do not use it, it causes problems.
With only two pools created with kqzfs I was able to finish several
bonnie++ benchmarks.
But anyway I have this worrying log in syslog (where sda3 is a kqzfs
pool)

I hope it can be useful to you.
Anyway I have done some tests and it seems that to complete tests you
should not have nay zfs-fuse filesystem imported.
Even if you do not use it, it causes problems.
With only two pools created with kqzfs I was able to finish several
bonnie++ benchmarks.
But anyway I have this worrying log in syslog (where sda3 is a kqzfs
pool)

I can second that. I am seeing this error too on my system with bonnie+

Ok I made a mistake. I have upgraded pool to version 28 but it has not
helped me. So now I have uninstalled kqzfs and installed zfs-fuse. But
zfs-fuse 0.7.0 supports only pool version 26. Is there a chance to go
back to version 26?
Thanks,
Mario

No. Destroy the pool and restore the backup on an older version

Since I have read in the forum that zfs server needs 4 gb of ram and
because my test server had only 2giga I exported the hdd containing
zfs pools as an iscsi target to another server with 4giga of ram.
The only result after bonnie++ and rsync test is that with more ram it
needs more time to hang but the result is the same.
Can you try to do a bonnie++ or rsync stress test on yours
filesystems?

Which os does support pool version 28?
I have tried to import pools with freebsd8.2 and with nexentastor
(based on solaris) and they say that pool version is too new for them.
It seems strange to me!

Yes you are correct. We have observed the problems. The one of the reason the why this happens is, in the write code (zfs_write) path, the code allocates memory using __vmalloc(). One of the parameter to the this function is the allocation flags (__GFP_NOFS). It is expected that when the memory is allocated using GFP_NOFS, the Linux Kernel will not callback the file system functions incase of memory pressure. Unfortunately there is a BUG in Linux Kernel see (https://bugzilla.kernel.org/show_bug.cgi?id=30702) for more details.
Anyway the Linux Kernel BUG fix will only be available in the new kernel release. We are also working on a workaround for the current kernels. I have a patch which solves this problem, but the change is taking more CPU resources than expected. I will send you a mail as soon as the changes are committed to the repository.
Thanks and Regards,
Prasad
