Hi, we're trying to run our database package with CephFS as the backing store and we're seeing constant freezes on filesystem accesses, apparently due to deadlocks in Ceph (all versions tested on 5.x kernels, 16.2.6 up to 18.2.2). I've made an issue on the tracker for it here with the details I've found so far: https://tracker.ceph.com/issues/67008 But if that's the wrong place to raise it, or if there are any additional details I could provide, please let me know. *********************************************************************************************************************************************************************** This email, its contents and any files attached are a confidential communication and are intended only for the named addressees indicated in the message.
