[DRBD-user] Error message: Failed to create meta-data for DRBD volume

Wed Apr 17 20:32:59 CEST 2019

Hi Gianni:

Thanks for your reply.

I added the filters in the lvm.conf file (I hope properly)

     global_filter = [ "r|/dev/zd.*|", "r|/dev/mapper/pve-.*|", "r|/dev/drbd.*|" ]

but the error is the same.

It only happens in the controller node:

linstor r l

One step which people usually miss, or misconfigure, is to setup lvm filters properly in /etc/lvm/lvm.conf file. Make sure that you have correctly added into lvm scan only devices that are really needed and remove  all the rest.

Hi everybody:

I have installed a cluster of 3 nodes with proxmox and all the Linstor components in each node.

I follow the steps of the guide "The DRBD9 and LINSTOR User's Guide" without any problems.

- linstor node create bravo 10.43.70.3

- vgcreate vg_ssd / dev / nvme0n1 / dev / nvme1n1 [...]

- linstor storage-pool create lvm alpha pool_ssd vg_ssd

- linstor resource-definition create backups

- linstor volume-definition create backups 500G

But when I try to do:

- linstor resource create alpha backups --storage-pool pool_hdd

I get the following error:

Error message: Failed to create meta-data for DRBD volume backups / 0

If the resource is created from the proxmox web interface, the error is:

Error: unable to create VM 100 - error with cfs lock 'storage-drbdstorage'. Could not place vm-100-disk-1 exit code 10

Any help would be appreciated

Regards,

Daniel
