Subject: Generic fencing command that Continues - msg#00159

List: linux.redhat.cluster

Date: Prev Next Index Thread: Prev Next Index
I'm setting up several "example" Clusters whith vmware.
The problem I have is that I don,t have a generic fencing tool.

If I give a demo to management ;-), my "very important" xclock service does
not recover after a killed server.
(I need to take manual actions :-(

What I need would be fencing command that does following:

- send an alert. (ex "mail -s Cluster operating@xxxxxxxxxxx")
- Wait for defined time ("sleep 15")
- Do some confirmation check.
- Execute a "Kill server" script, that doesn't stop
- Continue cluster and start de service on a working node.

If you have something like that or a part of it.....

If I'm doing something wrong, please correct me
(Or even correct way to disable fencing.)

Re: failover domain ip address hidden?

Greg, I had the very same doubt as you had. After digging into the manual, I could find a paragraph that instructed me to issue the following command to check the virtual IP addresses in the kernel: ip addr list Looking at the "ip" man page, I found that there is possible to make a "label" appear when you type "ifconfig", but for some reason the virtual IP scripts don't make use of this. For the developers: how about adding a text field where the user could type a short descriptive label for using together with the "ip addr add x.x.x.x dev INTERFACE label LABEL"? This way the label would appear when the user typed "ifconfig", right? Best regards, Celso. Greg Forte escreveu: Can anyone explain to me how failover ip addresses are bound to interfaces in the kernel, or why they don't seem to show up in 'ifconfig' output?  I've got one configured and it worked like a charm first try (unlike my fencing setup, heh), I'm just confused as to why it doesn't appear in ifconfig. -g Greg Forte gforte@xxxxxxxx IT - User Services University of Delaware 302-831-1982 Newark, DE -- Linux-cluster mailing list Linux-cluster@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/linux-cluster -- Celso Kopp Webber celso@xxxxxxxxxxxxxxxx Webbertek - Opensource Knowledge (41) 8813-1919 (41) 3284-3035

GFS6.1 and CS4.0 fencinfg RSA II

Hi. CS 3 and GFS 6.0 fencing ibm servers with RSA II adapter was done with fence_xcat, in CS 4.0 and GFS 6.1 there is no fence_xcat command. Is there some other mechanism to fence nodes which have RSA II adapters. Thanks for advance. ...................................................................

Basic question on CLVMD / GFS

Hi, I am confused about the usage of clvmd. On a blank 80 GB disk I created a logical volume using the following commands (after the cluster was started with "ccsd; cman_tool join; fence_tool join" on all nodes): # overwrite a former partition table: dd if=/dev/zero of=/dev/hdb bs=512 count=1 # initialize the physical volume: pvcreate /dev/hdb # create a volume group "vg301": vgcreate vg301 /dev/hdb # create a 40 GB logical volume "lvol0" inside vg301: lvcreate -L 40G vg301 # start clvmd clvmd # mark the volume group as "clustered" (there are no other vg's): vgchange -cy # activate the volume group with/without cluster locking vgchange -aey ...or... vgchange -aly vgchange prints a notice if on some other node of the cluster clvmd is not running and activates the logical volume. Is this enough to use "vg301" or "vg301/lvol0" on the other nodes? If yes, how do I access vg301 from another (than the local) node? vgscan, executed on the other nodes, does not report anything. Distributing the local vg301/lvol0 (with GFS on it) with GNBD 'nearly' worked: At some point, the I/O was blocked on nodes accessing a specific directory. gfs_mkfs -p lock_dlm -t Isabella:lvol0_301 -j 4 /dev/vg301/lvol0 gnbd_export -v -e exp301_0 -d /dev/vg301/lvol0 Is there any information / documentation about clvmd? The lvm-HOWTO does not cover this topic :-( Many thanks! -- Michael Weitzel

Cluster Suite v3 software watchdog

Hello, I'm having some difficulties with the software watchdog feature when configuring a Red Hat Cluster Suite v3 with Dell hardware. Notably I had problems with Dell PowerEdges 2650 and 2850. After setting up the cluster nodes and selecting the "enable software watchdog" check box under every member of the "Members" tab, I can run the cluster with no problems, but the machines reboot from time to time. I've tried passing the following parameters to the kernel by editing grub.conf: nmi_watchdog=1 Does anyone has had this issue before? Or am I missing any step on configuring the software watchdog feature? Another question for the Red Hat people on the list: does this "software watchdog" works ok? I ask because it's enabled by default when you add a new member to the cluster. The Cluster Suite v3 manual tells nothing about this resource either. I could only find some information about soft watchdog in the Cluster Suite v2.1 manual, but that version seems to be somewhat different from v3 and v4. Thanks in advance. Regards, Celso. -- Celso Kopp Webber
