FreeBSD and ISCSI, Strange Problem

2008-09-25 Thread Daniel Dias Gonçalves

I'm with a very strange problem in the FreeBSD 7.0R
I use the iscsi_initiator to mount two devices of a Dell MD3000i, the 
file system is UFS.
The problem occurs when I make a copy of a great directory for inside of 
the /data/email directory, passed some minutes of beginning of copy, the 
SSH connection stops to answer, when trying to open a new connection  
Password:  it isn't requested, in the console, when typing the user 
root e to press enter,  Password:  also it isn't requested. The only 
way to come back is restarting the FreeBSD.


When press CTRL+T during the freeze it is shown:
# ssh [EMAIL PROTECTED]
load: 0.76  cmd: ssh 86930 [sbwait] 0.00u 0.01s 0% 2076k

In another freeze it showed state [ufs]
During freeze, send and receive pings work fine, but no service runing work.

I already verified for some related LOG, however not see nothing related.

MOUNT:
/dev/da0s1g on /home (ufs, local, soft-updates)
/dev/da0s1f on /tmp (ufs, local, soft-updates)

Understanding Flags, Refs, Use, Expire in Routing Table

2008-03-27 Thread Daniel Dias Gonçalves
I would like an explanation on each field it command netstat - rn, 
example:

Flags,Refs,Use,Expire
In Flags: UGS, UC, UHLW, UH
Somebody can explain me ?

Thanks,

DEVICE_POLLING IF_EM CPU usage

2008-02-09 Thread Daniel Dias Gonçalves

Hi,

I activated polling in 8 interfaces em0... em7 (ifconfig em* polling) to 
carry through performance tests, when activating, it had a significant 
reduction of CPU usage, load average measured of 0,50, 0,69, 0,52 for 
0,43, 0,39, 0,21 and the CPU usage (SNMP Graphic) measured of 35% for 
5%. Passed some hours I disactivated polling (ifconfig em* - polling) 
and CPU usage continues low.

Somebody could explain this to me?

Some information:

FreeBSD 6.3-RELEASE

CPU: Intel(R) Xeon(TM) CPU 3.20GHz (3200.13-MHz 686-class CPU)
Logical CPUs per core: 2
FreeBSD/SMP: Multiprocessor System Detected: 2 CPUs
SMP: AP CPU #1 Launched!

Interfaces if_em:
  vendor = 'Intel Corporation'
  device = '82546EB Dual Port Gigabit Ethernet Controller'


Thanks.

Daniel
