Hi, I created an EXT4 partition on an RBD volume (0.72.1) on Ubuntu
(3.8.0-33) and noticed TRIM seems to be unsupported:
$ sudo fstrim /mnt/ceph
fstrim: /mnt/ceph: FITRIM ioctl failed: Operation not supported
It seems this is an open issue: http://tracker.ceph.com/issues/190
Is there some workaround or custom patch available to enable discard
support in the kernel driver?
