I have a strange error when trying to map via krdb on a RH (alma8) release / kernel 4.18.0-372.13.1.el8_6.x86_64 using ceph client version 14.2.22 (cluster is 14.2.16) the rbd map causes the following error in dmesg: [Tue Jul 19 07:45:00 2022] libceph: no match of type 1 in addrvec [Tue Jul 19 07:45:00 2022] libceph: problem decoding monmap, -2 I am able to map this rbd to a cent7 / 3.10.0-1160.71.1.el7.x86_64 machine using the same client and commands. Of note, on the RH8 node I can fetch info about the rbd and list rbds in the pool check ceph status etc. It seems purely limited to the mapping of the RBD: Info about the RBD: [root@alma8rbdtest ~]# rbd --id profilerbd info win-rbd-test/originalrbdfromsnap rbd image 'originalrbdfromsnap': size 5 GiB in 1280 objects order 22 (4 MiB objects) snapshot_count: 0 id: 2c5f465fa134c0 block_name_prefix: rbd_data.2c5f465fa134c0 format: 2 features: layering, exclusive-lock op_features: flags: create_timestamp: Mon Jul 18 13:58:39 2022 access_timestamp: Mon Jul 18 13:58:39 2022 modify_timestamp: Mon Jul 18 13:58:39 2022 anybody seen something like this Respectfully, *Wes Dillingham* wes@xxxxxxxxxxxxxxxxx LinkedIn <http://www.linkedin.com/in/wesleydillingham> _______________________________________________ ceph-users mailing list -- ceph-users@xxxxxxx To unsubscribe send an email to ceph-users-leave@xxxxxxx
