Hi Dejan, This is a known issue and please see https://tracker.ceph.com/issues/61009. For the workaround please see https://tracker.ceph.com/issues/61009#note-26. Thanks - Xiubo On 5/8/24 06:49, Dejan Lesjak wrote:
Hello, We have cephfs with two active MDS. Currently rank 1 is repeatedly crashing with FAILED ceph_assert(p->first <= start) in md_log_replay thread. Is there any way to work around this and get to accesible file system or should we start with disaster recovery?
