export administration regulations issue for ceph community edition

by Peter Parker

Does anyone know of any new statements from the ceph community or foundation regarding EAR? I read the legal page of ceph.com and mentioned some information. https://ceph.com/legal-page/terms-of-service/ But I am still not sure, if my clients and I are within the scope of the entity list, whether the use of ceph community edition complies with the corresponding laws. Whether it affects the current release and future releases.

pg stuck in unknown state

by Michael Thomas

On my relatively new Octopus cluster, I have one PG that has been perpetually stuck in the 'unknown' state. It appears to belong to the device_health_metrics pool, which was created automatically by the mgr daemon(?). The OSDs that the PG maps to are all online and serving other PGs. But when I list the PGs that belong to the OSDs from 'ceph pg map', the offending PG is not listed. # ceph pg dump pgs | grep ^1.0 dumped pgs 1.0 0 0 0 0 0 0 0 0 0 0 unknown 2020-08-08T09:30:33.251653-0500 0'0 0:0 [] -1 [] -1 0'0 2020-08-08T09:30:33.251653-0500 0'0 2020-08-08T09:30:33.251653-0500 0 # ceph osd pool stats device_health_metrics pool device_health_metrics id 1 nothing is going on # ceph pg map 1.0 osdmap e7199 pg 1.0 (1.0) -> up [41,40,2] acting [41,0] What can be done to fix the PG? I tried doing a 'ceph pg repair 1.0', but that didn't seem to do anything. Is it safe to try to update the crush_rule for this pool so that the PG gets mapped to a fresh set of OSDs? --Mike

iSCSI gateways in nautilus dashboard in state down

by Willi Schiegel

Hello All, I have a Nautilus (14.2.11) cluster which is running fine on CentOS 7 servers. 4 OSD nodes, 3 MON/MGR hosts. Now I wanted to enable iSCSI gateway functionality to be used by some Solaris and FreeBSD clients. I followed the instructions under https://docs.ceph.com/docs/nautilus/rbd/iscsi-target-cli-manual-install and https://docs.ceph.com/docs/nautilus/rbd/iscsi-target-cli/ I setup two iSCSI targets and they both show up with gwcli on both gateways: [root@osd1 ~]# gwcli ls ... o- gateways ..................... [Up: 2/2, Portals: 2] | o- osd1.mydomain.pri ......... [172.29.1.171 (UP)] | o- osd2.mydomain.pri ......... [172.29.1.172 (UP)] ... tcmu-runner, rbd-target-gw and rbd-target-api are active (running) on both gateways, there is no firewall and SELinux is disabled but on the dashboard the state of the gateways is "down". and ceph-mgr.mon2.log shows mgr[dashboard] iscsi REST API failed GET req status: 403 Any hints? Thank you. Best Willi

Data from the StorageClass mostly gets translated and sent via the "parameters" argument and data from the Secret gets translated and sent via the "secrets" argument of various gRPC requests.

anyone using ceph csi

by Marc Roos

I was wondering if anyone is using ceph csi plugins[1]? I would like to know how to configure credentials, that is not really described for testing on the console. I am running ./csiceph --endpoint unix:///tmp/mesos-csi-XSJWlY/endpoint.sock --type rbd --drivername rbd.csi.ceph.com --nodeid test Connection is fine [ ~]# csc identity plugin-info "rbd.csi.ceph.com" "canary" However I have no idea how to configure the clientid, pool etc in the volumes [1] https://github.com/ceph/ceph-csi Ps. I am not using kubernetes.
