Error when try to open hardware tab in nodes

[afrugone]

When I try to create a KVM guest or open the hardware tab on a existing KVM guest on any node server I get this error:

[5708]ERR: 24: Error in Perl code: 500 read timeout

I've looked for in the forum, but I didn't find anything useful for this error:

The configuration is a 3 nodes cluster PVE1 (master) and Nodes PVE2 and PVE0. I guess is something related with storage, as show in pvesm list -a (see bellow).

Any help is wellcome,

Thanks
Alfredo

Hi,
if you mount your nfs-share or remove them from the storage (gui, or /etc/pve/storage.conf) your error will gone.

Ok, I understand that, but on Master server is working without problem and /etc/pve/storage.conf is the same in all servers, And all backups are going to the NFS share, so I'll have to reconfigure all my backups. If there is not other solution I'll do it.

Thanks for your Help.

So why does it fail on the node? Maybe a permission problem on the NFS server?

 

[afrugone]

Dietmar,

Thanks for you help, but I don't think that is a permission problem, the NFS server is open. Anyway I'll remove the NFS and configure again, if the problem persist I'll tell you.

Thanks and Regards
Alfredo

I delete the NFS from config, now I can access the hardware tab, and seems to work without problem, but when I execute the pvesm list -a in a node I get the following, unfortunatelly I can not remode this iSCSI share because we have some KVMs running on it, and is running in the same node PVE02

Hi,
this messages shows, that your iscsi-disk are usable on two path - e.g. multipathing?! sdb and sdc are the same disks but connected over different networks?!
You can enable multipath on linux - search in the forum, some time ago someone has post a successfully usecase (if i'm right).

Hi guys,

I have the same issue. My cluster includes 1 master and 2 nodes. I've created a volume group within the master and when I try to access hardware tab on the others nodes I get the error message :

[1733]ERR: 24: Error in Perl code: command '/sbin/vgchange -aly drbdvg2' failed with exit code 5

hampton:/etc/pve# pvesm list -a

Volume group "drbdvg2" not found
command '/sbin/vgchange -aly drbdvg2' failed with exit code 5

Hi,
in a cluster (1.x) must be all shared storage reachable on all nodes. In your case the drbd-volumes are only accessible on two nodes.
You can do an hack - create simply on the other node the same named volumegroup on a usb-stick.
