It will be nice to include this in https://docs.linbit.com/docs/users-guide-9.0/#ch-proxmox chapter. But, I got a lot of messages on my syslog about PVE storage about every ten seconds : > Mar 19 18:54:02 dmz-pve1 pvestatd[1984]: Use of uninitialized value in > split at /usr/share/perl5/PVE/Storage/Custom/DRBDPlugin.pm line 217. > Mar 19 18:54:02 dmz-pve1 pvestatd[1984]: Use of uninitialized value > $free_space in multiplication (*) at > /usr/share/perl5/PVE/Storage/Custom/DRBDPlugin.pm line 220. > Mar 19 18:54:02 dmz-pve1 pvestatd[1984]: Use of uninitialized value > $total_space in multiplication (*) at > /usr/share/perl5/PVE/Storage/Custom/DRBDPlugin.pm line 221. > Mar 19 18:54:12 dmz-pve1 pvestatd[1984]: Use of uninitialized value in > split at /usr/share/perl5/PVE/Storage/Custom/DRBDPlugin.pm line 217. > Mar 19 18:54:12 dmz-pve1 pvestatd[1984]: Use of uninitialized value > $free_space in multiplication (*) at > /usr/share/perl5/PVE/Storage/Custom/DRBDPlugin.pm line 220. > Mar 19 18:54:12 dmz-pve1 pvestatd[1984]: Use of uninitialized value > $total_space in multiplication (*) at > /usr/share/perl5/PVE/Storage/Custom/DRBDPlugin.pm line 221. > Mar 19 18:54:22 dmz-pve1 pvestatd[1984]: Use of uninitialized value in > split at /usr/share/perl5/PVE/Storage/Custom/DRBDPlugin.pm line 217. > Mar 19 18:54:22 dmz-pve1 pvestatd[1984]: Use of uninitialized value > $free_space in multiplication (*) at > /usr/share/perl5/PVE/Storage/Custom/DRBDPlugin.pm line 220. > Mar 19 18:54:22 dmz-pve1 pvestatd[1984]: Use of uninitialized value > $total_space in multiplication (*) at > /usr/share/perl5/PVE/Storage/Custom/DRBDPlugin.pm line 221. In proxmox interface I have no idea of free space on my drbdpool VG. Initialize the cluster create /dev/drbdpool/.drbdctrl_0 and /dev/drbdpool/.drbdctrl_1. For the moment no cluster are created for drbd and for proxmox.
/etc/drbdmanaged.cfg contain : [LOCAL] storage-plugin = drbdmanage.storage.lvm_thinlv.LvmThinLv force=1 and /etc/pve/storage.cfg : dir: local path /var/lib/vz content iso,vztmpl,backup drbd: drbdstorage content images,rootdir redundancy 3 Any Ideas ? Thanks in advance Regards, JdT
