our oracle(oracle 10G) server got a serious problem, the OS is SLES 9 SP4, two HBA adapters(QLogic 2340) with NetApp FC Storage(FAS3140), we have installed multipath-tools on this server and ensure that physical connection and swith configuration are correct, but we only can see a path
:~ # multipath -ll

[size=200G][features=0][hwhandler=0]
[code]....
i want to remove a path, but is in use.. How can i kill the zombie processes?
[Code]....
I guess i was wrong deleting first the disks that formed the path, but now how could i kill those zombie processes without a reboot?
[Code]....
Could you please advice how to clone CentOS with all installed software to another box.
What tools should be used?
Is there a firewall installed and running in 10.04? If so are there any gui tools for configuring it and where are they? If there is not a firewall, what should I install to get one properly up and running?
View 2 Replies View RelatedIt used to be that the dvd menu offered an option to "repair the installed system". THis was really very convenient. The openSUSE 11.3 dvd for x86 now only gives a "system rescue" option which leads to command line directl. Where have been "the repair the installed system" tools? How can we access them now? What is a reasonable set of tips that's supposed to be used after logging into "system rescue"?

I need to set up 1 disk, the disk is presented to the server on both fibre paths from the SAN. This is the current setup seen:
[Code]..
I have and RHEL5.4 conecceted to an SAN HSV200. When I present a LUN to it, In system-confg-lvm gui appears a device like /dev/mapth/mapth0 (that�s the correct device to multipath) and other like /dev/sda or /dev/dm-N, as uninitialized entities. How could I configure to not display this device (/dev/sda) and prevent human errors?
This is the things I need:
1- I want (if it is posible...) to disappear the part where it says "uninitialized entities"
2- Is It necesary mantain the partitioning done to default (like /dev/mapper/mpath0p1) with device-mapper-multipath (kpartx command)? or Can I delete it without future problems?
This is the actual configuration that I have:
1- /etc/lvm/lvm.conf
Code:
preferred_names = [ "^/dev/mpath/", "^/dev/mapper/mpath", "^/dev/[hs]d" ]
filter = [ "a/dev/mapper/mpath.*/","a/dev/cciss/.*/","r/.*/" ]
2- /etc/multipath.conf

I upgraded a DL580 G4 server from Red Hat 4.4 to 5.2 (2.6.18-92.el5 #1 SMP Tue Apr 29 13:16:15 EDT 2008 x86_64 x86_64 x86_64 GNU/Linux) and now when I run the multipath - l command I only see one path. There are 4 LUNs being presented on each fibre channel, so I should see sda - sdh in /dev, but I only see sda - sdd.

There is a server with two HBA QLA2460, connected via SAN to the SE9980 disk array. RHEL 5.4 (x86_64) is running on the server. In the SAN two zones are set up: HBA1-port1 9980; HBA2 - port2 SE9980. As a result, the server can see:

We have few servers and we need to monitor mysql and ping (port 80) on our servers to send us email notification and also we need sms notification when something is wrong, we can ask our developer to write sms notification (which is very important for us) because we already have the API and only need a output from a good monitoring tools to show to our developer and ask him to write the notification program.
Our primary sever is centos with WHM installation and hosts about 600 websites.(need to monitor mysql & port 80 on this.)The secondary one is windows server with virtuzzu installation and host about 15 windows VPS (The server crashing some times and we need to findout its out of service ASAP .)Should we use monitoring websites such as hypersins.com or siteuptime.com (which is a little expensive for us especially because of international sms rates.) or there is nice tools we can easily configure and use !
After mapping iscsi storage from my netapp and scanning for new devices I run multipath -v2 to create the multipath device handle under /dev/mapping/. This normally takes about 2 seconds or less on every other linux distribution I use. On Stretch it takes a little over 3 minutes. I have tried several different versions of multipath.conf but the result is always the same.
My most recent multipath.conf file is available here : [URL] ....

I have a linux machine, attached to a fibre channel SAN.
We're in the testing phases and we're attempting to get all of the bugs worked out before this goes live.
If i have my host streaming data to the storage device on the san (or from the device on the san) and simulate a path failure (by shutting down one of the host's ports on the FC switch), multipath does not pick up on another path until about 45 seconds have passed.
I can verify this by watching the statistic graph (which updates once per second) on the storage system.
I see iops running along rather nicely, and then they drop to 0 for 45 seconds, then pick right up to normal again.
This is a RehHat EL 5.5 system, with qlogic HBA's.
Am i being too picky? I'd expect multipath to recover in under 30 seconds, so as to not alarm host applications running on the linux host... 45 seconds seems like a long time to wait for a disk operation to complete.
Any tips on tuning Multipath, or the qlogic card? As it is, i've got the following options in my modprobe.conf.

View 1 Replies View RelatedI've been busy with configuring Samba with the 389-Directory Server (former Fedora Directory Server) for the past weeks and I almost have everything working. The last thing (I hope) that I haven working are the smbldap-tools which I'd like to use for adding computers and users to the domain. The part where I'm stuck is with the security certificates. I don know how to get the client certificates out of my installation.
My smbldap.conf file contains this:

I used the setupssl2.sh script to setup ssl for my 389-ds, which seemed to have worked fine. I however simply have no clou how to get client certificates out of this.
