Hi Ranjan, Which kernel did you downgrade to? Looking at the changelog, disco's 5.0.0-32 kernel has the botched backport mentioned in the coreos issue you linked to. Downgrading to 5.0.0-31 should help, until disco picks up the fix (either just the revert or the revert plus the new backport). Revert "ceph: use ceph_evict_inode to cleanup inode's resource" ceph: use ceph_evict_inode to cleanup inode's resource Thanks, Ilya _______________________________________________ ceph-users mailing list -- ceph-users@xxxxxxx To unsubscribe send an email to ceph-users-leave@xxxxxxx
