zpool errors without fmdump or dmesg errors
Hi all,
I am running S11 on a Dell PE650. It has 5 zpools attached that are made
out of 240 drives, connected via fibre. On thursday all of the sudden
two out of three zpools on one FC channel showed numerous errors and one
of them showed this:
root at solaris11a:~# zpool status vsmPool01
pool: vsmPool01
state: SUSPENDED
status: One or more devices is currently being resilvered. The pool

SAS/short stroking vs. SSDs for ZIL
Hi,
as I have learned from the discussion about which SSD to use as ZIL
drives, I stumbled across this article, that discusses short stroking
for increasing IOPs on SAS and SATA drives:
http://www.tomshardware.com/reviews/short-stroking-hdd,2157.html
Now, I am wondering if using a mirror of such 15k SAS drives would be a
good-enough fit for a ZIL on a zpool that is mainly used for file

Can I "upgrade" a striped pool of vdevs to mirrored vdevs?
Hi,
once I created a zpool of single vdevs not using mirroring of any kind. Now I wonder if it''s possible to add vdevs and mirror the currently existing ones.
Thanks,
budy

How to rename rpool. Is that recommended ?
Hello,
I have a situation where a host, which is booted off its ''rpool'', need
to temporarily import the ''rpool'' of another host, edit some files in
it, and export the pool back retaining its original name ''rpool''. Can
this be done ?
Here is what I am trying to do:
# zpool import -R /a rpool temp-rpool
# zfs set mountpoint=/mnt

ZFS slows down over a couple of days
Hi all,
I have exchanged my Dell R610 in favor of a Sun Fire 4170 M2 which has
32 GB RAM installed. I am running Sol11Expr on this host and I use it to
primarily serve Netatalk AFP shares. From day one, I have noticed that
the amount of free RAM decereased and along with that decrease the
overall performance of ZFS decreased as well.
Now, since I am still quite a Solaris newbie, I seem to

Running on Dell hardware?
I have a Dell R710 which has been flaky for some time. It crashes about
once per week. I have literally replaced every piece of hardware in it, and
reinstalled Sol 10u9 fresh and clean.
I am wondering if other people out there are using Dell hardware, with what
degree of success, and in what configuration?
The failure seems to be related to the perc 6i. For some period around the

NFS performance issue
Hi!
I searched the web for hours, trying to solve the NFS/ZFS low performance issue on my just setup OSOL box (snv134). The problem is discussed in many threads but I''ve found no solution.
On a nfs shared volume, I get write performance of 3,5M/sec (!!) read performance is about 50M/sec which is ok but on a GBit network, more should be possible, since the servers disk performance

zpool import panics
Hi,
I just had my Dell R610 reboot with a kernel panic when I threw a couple
of zfs clone commands in the terminal at it.
Now, after the system had rebooted zfs will not import my pool anylonger
and instead the kernel will panic again.
I have had the same symptom on my other host, for which this one is
basically the backup, so this one is my last line if defense.
I tried to run zdb -e

copy complete zpool via zfs send/recv
Hi,
I want to move all the ZFS fs from one pool to another, but I don''t want
to "gain" an extra level in the folder structure on the target pool.
On the source zpool I used zfs snapshot -r tank at moveTank on the root fs
and I got a new snapshot in all sub fs, as expected.
Now, I want to use zfs send -R tank at moveTank | zfs recv targetTank/...
which would place all zfs fs

[PATCH]Add address overflow check
Pointers are unsigned so this shouldn't be an issue. I suspect you're
being hit by something else. That or your compiler is really broken.

[PATCH]Add address overflow check
Hi,
I came into a crash when using 32-bit `speexdec` and found that there's an
address overflow in function `print_comments()`:
static void print_comments(char *comments, int length)
{
char *c=comments;
int len, i, nb_fields;
char *end;
if (length<8)
{
fprintf (stderr, "Invalid/corrupted comments\n");
return;
}
end = c+length;

Using lib Rstreams and gzfile()
Hi all,
in the last time I've intensively used Rstreams to read and write from
binary files. Now I'm wondering if it is possible to use Rsteams
functions with gzipped files. But I haven't found the trick:

> readBin(p1c.gzip, integer(), n=64,size=2)

Dear Jean-Marc and Peter:
Thank you both very much for your time and advice. I did not realize that Lame MP3 code has a -r option (without reading its code). I have tried the suggested command lines verbatim with the added -r option, along with other combination of option settings. I could not figure out how to eliminate the distortion in the result, like voice turning either high or low

Performance drop during scrub?
Hi all
I have a test system with snv134 and 8x2TB drives in RAIDz2 and currently no Zil or L2ARC. I noticed the I/O speed to NFS shares on the testpool drops to something hardly usable while scrubbing the pool.
How can I address this? Will adding Zil or L2ARC help? Is it possible to tune down scrub''s priority somehow?
Best regards
roy

Binary file functions in R
This is just to let people know that I'm going to try to put together
a little package of binary file read/write functions for R, along the
lines described in my message in r-help. I'm going to do it first in
R for Windows using a DLL written in Delphi; I'll let people comment
on that, and once the design settles down, I'll redo the external code
in C so that it should be portable

Do you have the sha1 hashes for any of those patches? I might be able
