Hello, So to continue with my experiments with drbdmanage and thinlv plugin :
drbdmanage 0.91 (same thing seems to happen with 0.50). storage-plugin = drbdmanage.storage.lvm_thinlv.LvmThinLv I create a VM with proxmox, 10 GB disk. Right after, I got this free pool space with drbdmanage list-nodes : > +------------------------------------------------------------------------------------------------------------+ > | Name | Pool Size | Pool Free | > | State | > |------------------------------------------------------------------------------------------------------------| > | vm4 | 523264 | 521066 | > | ok | > | vm5 | 523264 | 521066 | > | ok | > +------------------------------------------------------------------------------------------------------------+ This is right for vm4 (thin pool is 511 GB) with thin provisionned : --- Logical volume --- LV Name drbdthinpool LV Size 511.00 GiB Allocated pool data 0.00% Allocated metadata 0.43% but can't be considered as right for vm5 : --- Logical volume --- LV Name drbdthinpool LV Size 511.00 GiB Allocated pool data 1.96% Allocated metadata 1.43% AFAIK, drbdmanage should report 511*1024*(1-1.96/100)= 513008 MB free. (almost my 10GB disk size from 523264 MB). Now, I created an 5GB disk : > +------------------------------------------------------------------------------------------------------------+ > | Name | Pool Size | Pool Free | > | State | > |------------------------------------------------------------------------------------------------------------| > | vm4 | 523264 | 521013 | > | ok | > | vm5 | 523264 | 505525 | > | ok | > +------------------------------------------------------------------------------------------------------------+ Wow, so that WAS updated, even before the initial sync finish. Let's wait for sync to finish and delete this new 5GB disk : still the same report. So I'm wondering how and when 'pool free' value is calculated. Is it recalculated only when a new ressource is created ? deleted ? Is there a way to force it to rescan free space ? (with a dbus command perhaps ?) That could perhaps be done by a cron job running at defined frequency ? Regards, Julien
