Hi, I created an encrypted volume which appears to be working fine with FUSE but the volume is supposed to store VM images (master key in place). I noticed some references in libgfapi source code to encryption so I decided to try it out. While attempting to create an image: # qemu-img create -f qcow2 gluster://gluster01/virt0/testing.img 30G Formatting 'gluster://dalpinfglt01/virt0/testing.img', fmt=qcow2 size=32212254720 encryption=off cluster_size=65536 lazy_refcounts=off refcount_bits=16 [2017-06-02 18:30:37.489831] E [mem-pool.c:579:mem_put] (-->/lib64/libglusterfs.so.0(syncop_lookup+0x4e5) [0x7f2abbe66d35] -->/lib64/libglusterfs.so.0(+0x59f02) [0x7f2abbe62f02] -->/lib64/libglusterfs.so.0(mem_put+0x190) [0x7f2abbe54a60] ) 0-mem-pool: mem-pool ptr is NULL [2017-06-02 18:30:37.490715] E [mem-pool.c:579:mem_put] (-->/lib64/libglusterfs.so.0(syncop_lookup+0x4e5) [0x7f2abbe66d35] -->/lib64/libglusterfs.so.0(+0x59f02) [0x7f2abbe62f02] -->/lib64/libglusterfs.so.0(mem_put+0x190) [0x7f2abbe54a60] ) 0-mem-pool: mem-pool ptr is NULL [2017-06-02 18:30:37.492255] E [mem-pool.c:579:mem_put] (-->/lib64/libglusterfs.so.0(syncop_lookup+0x4e5) [0x7f2abbe66d35] -->/lib64/libglusterfs.so.0(+0x59f02) [0x7f2abbe62f02] -->/lib64/libglusterfs.so.0(mem_put+0x190) [0x7f2abbe54a60] ) 0-mem-pool: mem-pool ptr is NULL ........ Am I to understand that libgfapi doesn't support encryption at rest?
