I'm testing ceph in my enviroment, but the feature exclusive lock don't works
fine for me or maybe i'm doing something wrong.
I testing in two machines create one image with exclusive-lock enable, if I
understood correctly, with this feature, one machine only can mount and write
in image at time.
But When I'm testing, i saw the lock always is move to machine that try mount
the volume lastly
Example if i try mount the image in machine1 i see ip the machine1 and i mount
the volume in machine1 :
#rbd lock list test-xlock3
There is 1 exclusive lock on this image.
Locker
ID
Address
client.4390 auto XXXXXXXXXXXXXXXX 192.168.0.1:0/2940167630
But if now i running rbd map and try mount image in machine2, the lock is
change to machine2, and i believe this is one error, because if lock already in
machine one and i write in image, the machine2 don't should can mount the same
image in the same time.
If i running in machine2 now, i see :
#rbd lock list test-xlock3
There is 1 exclusive lock on this image.
Locker
ID
Address
client.4491 auto XXXXXXXXXXXXXXXXXX 192.168.0.2:0/1260424031
Exclusive-lock enable in my image :
rbd info test-xlock3 | grep features
features: exclusive-lock
i'm doing some wrong ? Existing some conf, to add in ceph.conf, to fix this, if
one machine mount the volume, the machine2 don't can in the same time, i read
about command rbd
lock, but this command seem deprecated.
Thanks, a lot.
