change uid/god below 100
Hi.
Only indirectly related to zfs. I need to test diskusage/performance
on zfs shared via nfs. I have installed nevada b64a. Historically
uid/gid for user www has been 16/16 but when I try to add uid/gid www
via smc with the value 16 I''m not allowed to do so.
I''m coming from a FreeBSD backgroup. Here I alter uid using vipw and
edit /etc/group afterwards.

Vista and "System error 53 has occurred"
Hi,
Problem:
Out of the blue Vista on my laptop decides it doesn't want to mount a share over PPTP VPN connection. I can mount the share in the local network but I can't do it over VPN. When trying to access the server, using "net view \\172.16.1.71" it shows the error in the subject.

Windows Vista password dialog keeps coming up
Hi,
I have come to my wits end again (lately, it's a very short trip). I have been trying to connect to Samba 3.0.21b but Windows keeps throwing up the logon dialog. I'm using "Map network drive" to try to mount this share.
It seems the problem is only on the Windows side since I have tested the connection through the Unix account. Both user id and password work fine.

ZFS extended ACL
What is wrong with this?
# chmod -R A+user:webservd:add_file/write_data/execute:allow /var/apache
chmod: invalid mode: `A+user:webservd:add_file/write_data/execute:allow''
Try `chmod --help'' for more information.
This works in a zone, works on S10u5, does not work on OpenSolaris2008.11.

Pfilestat vs. prstat
[Just starting out with DTrace and was hoping to get some guidance.]
I have a "benchmark" program that I monitored with both prstat (prstat -mL -P <PID>) and pfilestat (from the DTrace toolkit). Prstat reports LAT values in the 0.1-0.2% range, but pfilestat reports "waitcpu" values in the 6-10%. Since those two numbers supposedly represent time waiting for the CPU,

memory allocation
hello!
First of all thank you for all your information you give us on this sites. It is a great help to learn for example dtrace.
i''ve a little script in work, which shows the cpu utilization per process in percent. this output is refreshed every 2 seconds for example.
now i want to extend this script with the output of the allocated bytes of memory per process.
how could i display this

prstat -Z and load average values in different zones give same numeric results
Folks,
Perplexing question about load average display with prstat -Z
Solaris 10 OS U4 (08/07)
We have 4 zones with very different processes and workloads..
The prstat -Z command issued within each of the zones, correctly displays
the number of processes and lwps, but the load average value looks
exactly the
same on all non-global zones..I mean all 3 values (1,5,15 load averages)
are the same

With RAID-Z2 under load, machine stops responding to local or remote login
Hi world,
I have a 10-disk RAID-Z2 system with 4 GB of DDR2 RAM and a 3 GHz Core 2 Duo.
It''s exporting ~280 filesystems over NFS to about half a dozen machines.
Under some loads (in particular, any attempts to rsync between another
machine and this one over SSH), the machine''s load average sometimes
goes insane (27+), and it appears to all be in kernel-land (as nothing

What has been swapped out?
I have a SunRay server that I am looking at to determine some sizing requirements in my department. The machine has 16G of ram and 10G of swap. Currently, I have about 4G of swap used. I am wondering if dtrace/mdb can be used to find out what lwp/processes have been swapped out?
Any hints?

Dtrace scripts for performance data gathering
I am looking for Dtrace scripts that can be used to
collect data during performance tests. I am especially
interested in IO but CPU, memory, threads, etc are needed
as well.

master/config rewrite
I've finally got it to work, kind of .. It should allow you to log in,
but several settings don't work yet and there are probably many bugs.
Anyway, I thought I'd show this already in case someone is interested
of looking how it works :)
One thing I'm still wondering a bit is if I should show process names
as:

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

find thread that is causing high cpu usage
Hello,
Using one of Brendan''s dtrace script prusage and prstat, I was able to find the process that is consuming high cpu. I also have a test case that can trigger this high cpu usage.
Questions are
a) how do I proceed from here?
b) how do I figure out which thread is using this high cpu?
c) how do I figure out which piece of code is causing this problem?
Thanks

VPN and NetBIOS aliases
Hi,I'm wondering if anyone has run into this but I found out that I can't use Window's VPN connection and logon to Samba using Aliases. I can log into the server using the server's main NetBIOS name but I can't use any of the aliases. Whilst inside the network the aliases work fine.Any ideas on how to get around this?# Samba config file created using SWAT
