I'm following Falko 's "Xen Cluster Management With Ganeti On Debian Lenny" and run to kinda simple problem but cannot resolve it. At the point "7 Adding node2.example.com To The Cluster" : --------------------------------------------------------------- vili3:~# gnt-node add vili4.domain.fi -- WARNING -- Performing this operation is going to replace the ssh daemon keypair on the target machine (vili4.domain.fi) with the ones of the current one and grant full intra-cluster ssh root access to/from it Failure: command execution error: Node 'vili4.domain.fi' claims it has a different hostname than the one the resolver gives: hostname mismatch, got vili4. Please fix and re-run this command. vili3:~# --------------------------------------------------------------- I have 2 nodes installed from scratch with same hardware. Reverse dns names are correct in nameservers, and /etc/hosts also. "ssh [email protected]" works ok also. Any ideas ?
Era necessario I have resolved: Was necessary also, the file /etc/hostname which configures the hostname of the system should contain node1.example.com and not just node1. Hello
followed the how-to and just can't figure out why the command gnt-cluster verify gives me following output: * Verifying global settings * Gathering data (1 nodes) * Verifying node emotion1.EMOTION - ERROR: ssh communication with node 'emotion1.EMOTION': hostname mismatch, got emotion1 * Verifying orphan volumes ... more than this - if i add an instance it just "seems" to work, but is in ERROR_down state if i try to connect. tia for any help emo
hell yes ... hostname / uname -n was emotion1 although it should have been emotion.EMOTION ... i'm so had tripple checked that but didn't realize it big thx for that anyway - now that the cluster is up and running - i can't add an instance. gnt-instance add -t drbd -n emotion1.EMOTION:emotion2.EMOTION -o debootstrap -s 2500 --swap-size 256 -m 64 --kernel /boot/vmlinuz-2.6.26-1-xen-686 --ip 192.168.1.111 inst1.EMOTION the * creating instance disks... part takes years (*g*) and than finally fails and exits. i looked at the lvm (with lvdisplay) and can see that those two disks are being created at node2 (emotion2) but nothing happens on node1 (emotion1). seems strage to me - has anyone a clue of what i'm missing ... error - (gnt-instance add) ########## Unhandled error in Deferred: Traceback (most recent call last): File "/usr/lib/python2.5/site-packages/twisted/spread/pb.py", line 526, in expressionReceived method(*sexp[1:]) File "/usr/lib/python2.5/site-packages/twisted/spread/pb.py", line 895, in proto_answer d.callback(self.unserialize(netResult)) File "/usr/lib/python2.5/site-packages/twisted/internet/defer.py", line 243, in callback self._startRunCallbacks(result) File "/usr/lib/python2.5/site-packages/twisted/internet/defer.py", line 312, in _startRunCallbacks self._runCallbacks() --- <exception caught here> --- File "/usr/lib/python2.5/site-packages/twisted/internet/defer.py", line 328, in _runCallbacks self.result = callback(self.result, *args, **kw) File "/var/lib/python-support/python2.5/ganeti/rpc.py", line 94, in cb_done tb)) ganeti.errors.RemoteError: Remote procedure error calling blockdev_create on emotion2.EMOTION: Traceback (most recent call last): File "/usr/sbin/ganeti-noded", line 87, in perspectiveMessageReceived state = method(*args, **kw) File "/usr/sbin/ganeti-noded", line 104, in perspective_blockdev_create return backend.CreateBlockDevice(bdev, size, owner, on_primary, info) File "/var/lib/python-support/python2.5/ganeti/backend.py", line 839, in CreateBlockDevice " daemon logs" % errorstring) BlockDeviceError: Can't assemble device after creation, very unusual event - check the node daemon logs failed to create volume sda (<DRBD8(hosts=emotion1.EMOTION-emotion2.EMOTION, port=11006, configured as 192.168.1.101:11006 192.168.1.100:11006, backend=<LogicalVolume(/dev/xenvg/76cd733a-2b01-4c5c-a60b-49beabd04ad1.sda_data, not visible, size=2500m)>, metadev=<LogicalVolume(/dev/xenvg/49369ca3-930f-426f-b023-8e408afd744e.sda_meta, not visible, size=128m)>, visible as /dev/sda, size=2500m)>) on secondary node emotion2.EMOTION!
