Re: [ceph-users] mds.0.journaler.pq(ro) _finish_read got error -2

Hi, I'm trying to help someone with a broken CephFS. We managed to recover basic ceph functionality but the CephFS is still inaccessible (currently read-only). We went through the disaster recovery steps but to no avail. Here's a snippet from the startup logs: ---snip--- mds.0.41 Booting: 2: waiting for purge queue recovered mds.0.journaler.pq(ro) _finish_probe_end write_pos = 14797504512 (header had 14789452521). recovered. mds.0.purge_queue operator(): open complete mds.0.purge_queue operator(): recovering write_pos monclient: get_auth_request con 0x55c280bc5c00 auth_method 0 monclient: get_auth_request con 0x55c280ee0c00 auth_method 0 mds.0.journaler.pq(ro) _finish_read got error -2 mds.0.purge_queue _recover: Error -2 recovering write_pos mds.0.purge_queue _go_readonly: going readonly because internal IO failed: No such file or directory mds.0.journaler.pq(ro) set_readonly mds.0.41 unhandled write error (2) No such file or directory, force readonly... mds.0.cache force file system read-only force file system read-only ---snip--- I've added the dev mailing list, maybe someone can give some advice how to continue from here (we could try to recover with an empty metadata pool). Or is this FS lost?
