Nevermind, was not having discard='unmap' in libvirt -----Original Message----- To: ceph-users Subject: rbd lvm xfs fstrim vs rbd xfs fstrim If I do an fstrim /mount/fs and this is an xsf directly on a rbd device. I can see space being freed instantly with eg. rbd du. However when there is an lvm in between, it looks like this is not freed. I already enabled issue_discards = 1 in lvm.conf but as the comment says, probably only in case of lvremove. Is it possible to get fstrim working with lvm? _______________________________________________ ceph-users mailing list -- ceph-users@xxxxxxx To unsubscribe send an email to ceph-users-leave@xxxxxxx _______________________________________________ ceph-users mailing list -- ceph-users@xxxxxxx To unsubscribe send an email to ceph-users-leave@xxxxxxx
