[Linux-cluster] dlm_resdir(s)': Can't free all objects

[Andriy Galetski]

Hi!
Can anyone explain ?
2 node cluster working.
When I  remove GFS modules from kernel on one node - get next messages :

Sep 10 11:53:26 cl20 gfs: Umount GFS filesystems:  succeeded
Sep 10 11:53:27 cl20 kernel: CMAN: we are leaving the cluster
Sep 10 11:53:28 cl20 gfs: ccsd shutdown succeeded
Sep 10 11:53:28 cl20 kernel: slab error in kmem_cache_destroy(): cache
