Issue with drbd (bm_rw_range.constprop) during resource migration 9.2.12 #107
Description
Hello,
We use Linstor and are trying to migrate a resource from one node to another. During the migration drbd spits out a trace & the volume is corrupted on the destination node.
Any help with this is appreciated!
Pools are ZFS_THIN
Nodes (Ubuntu 22.04):
cstdsc0-0 - controller & satellite
cstdsc1-0 - satellite
cstdsc1-1 - satellite
Resource is created on cstdsc0-1 (Diskless) & cstdsc1-1 (Diskfull)
We create the Diskless resource on cstdsc0-0 & migrate from cstdsc1-1
