Hi experts, I have implemented squid for my school environment. How to testing it for the security? ingoing and outgoing? Thanks before. Regards,

Hi all, I have problem with my servers. I use two of HP Blade Servers and RHEL 4.6 installed on them, and have IBM DS4700 connected to them. In those servers are running RHCS (Red Hat Cluster Suite) with GFS for handling Oracle Database. Yesterday, I had missing one partition from the storage, suddenly. I called IBM and they suggested to use RDAC. The question is, Why should use IBM RDAC for

Hi All, I have 2 LAN interfaces, and just added a new one, but it wouldn't configure. when I finished configure and I run command ifup eth2 appeared error message : netmask: Host name lookup failure Need your help soon. Thanks,

Here is a sample of running iostat on a server that has a LUN from a SAN with multiple paths. I am specifying a device list that just grabs the bits related to the multi path device: $ iostat -dxkt 1 2 sdf sdg sdh sdi dm-7 dm-8 dm-9 Linux 2.6.18-371.8.1.el5 (db21b.den.sans.org) 06/20/2014 Time: 02:30:23 PM Device: rrqm/s wrqm/s r/s w/s rkB/s wkB/s avgrq-sz avgqu-sz await

I updated an i386 system to b39 yesterday, and noticed this when running iostat: r/s w/s kr/s kw/s wait actv wsvc_t asvc_t %w %b device 0.0 0.5 0.0 10.0 0.0 0.0 0.0 0.5 0 0 c0t0d0 0.0 0.5 0.0 10.0 0.0 0.0 0.0 0.6 0 0 c0t1d0 0.0 65.1 0.0 119640001.5 0.0 0.0 0.0 0.3 0 2 c0t2d0 0.0 65.1 0.0 119640090.2 0.0

Hello, We are planning to moving most of our servers to ESX but before buying our SAN, we want to do some I/O stats to see if iSCSI is enough or if we have to go with FC. So I found a plugin for Nagios that can log I/O stats with iostat. So far it's fine with single disk/one partition servers, but on our Oracle Database 10g server, we have two drives in RAID 1 (/dev/sda) and 4 other

on Solaris 10 5.10 Generic_118822-23 sun4v sparc SUNW,Sun-Fire-T200 I run #iostat -xn 5 to monitor the IO statistics on SF T2000 server. The system also have a heavy IO load, for some reason iostat donot refresh (no any update). It seems like iostat is calling pause() and stucked there. Also my HBA driver''s interrupt stack trace indicates there is a lot of swtch(), the overall IOPS

Hi All, I am learning iostat command to understand disk I/O statistics. We have 2 Centos 4 servers running where oracle is installed.We installed them 2 weeks ago. @ that time, These Servers performed well. But, Now We have come to know that these 2 Machines are quite slow when comparing to the first week. So, Some say, run iostat to see statictics. I am not familiar with comamnd well. I

What is the best way to tell if your bound by the number of individual operations per second / random io? "zpool iostat" has an "operations" column but this doesn''t really tell me if my disks are saturated. Traditional "iostat" doesn''t seem to be the greatest place to look when utilizing zfs.

Is there anyway to tell with top or iostat which process is hogging all the disk I/O? Matt

I''m trying to write a SLAMD (http://www.slamd.com/) resource monitor that can be used to measure the I/O throughput on a ZFS pool, and in particular to be able to get the read and write rates. In order to do this, I''m basically executing "zpool iostat {interval}" and parsing the output to capture the values in the "bandwidth read" and "bandwidth

Hi gurus, I like zpool iostat and I like system monitoring, so I setup a script within sma to let me get the zpool iostat figures through snmp. The problem is that as zpool iostat is only run once for each snmp query, it always reports a static set of figures, like so: root at exodus:snmp # zpool iostat -v capacity operations bandwidth pool used avail read

Greetings, I've hit this exact 'bug': https://bugzilla.redhat.com/show_bug.cgi?id=491311 I need to remove the mappings manually. I assume this is done via 'multipath -F' followed by a 'multipath -v2' ? Has anyone experienced doing this on a production system? We can do it during hours of low activity, but we would prefer to keep the databases on this host online at

Hey guys, I need to use iostat to diagnose a disk latency problem we think we may be having. So if I have this disk partition: [root at uszmpdblp010la mysql]# df -h /mysql Filesystem Size Used Avail Use% Mounted on /dev/mapper/MysqlVG-MysqlVol 9.9G 1.1G 8.4G 11% /mysql And I want to correlate that to the output of fdisk -l, so that I can feed the disk

Hello ZFSland, Is there any significance in the fact that the bandwidth/read figures for a simple cpio into a ZFS filesystem should be multiples of 21.3K (when non-zero) as follows? What could determine this figure? Do I need to read a manpage? ;-) Thanks... Sean. ----- [root at global:/36g2] # zpool iostat 3 capacity operations bandwidth pool used avail read

Just started messing with multipath against an iSCSI target with 4 nics. What should one expect as behavior when paths start failing? My lab setup was copying some data on a mounted block device when I dropped 3 of 4 paths and the responsiveness of the server completely tanked for several minutes. Is that still expected? Thanks, jlc

I''m trying to set up a iscsi connection (with MPXIO) between my Vista64 workstation and a ZFS storage machine running OpenSolaris 10 (forget the exact version). On the ZFS machines, I have two NICS. NIC #1 is 192.168.1.102, and NIC #2 is 192.168.2.102. The NICs are connected to two separate switches serving two separate IP spaces. On my Vista64 machine, I also have two NICs connected in

hi all We have a rh linux server connected to two HP SAN controllers, one an HSV200 (on the way out), the other an HSV400 (on the way in).
