Hay

Ceph version 10.2.5

i have had an Ceph cluster going for a few months, with iscsi servers that
are linked to Ceph by RBD.

All of an sudden i am starting the ESXI server will louse the isscsi data
store (disk space goes to 0 B) and i only fix this by rebooting the ISCSI
server

When checking syslogs on the iscsi server i get a loads of errors like

SENDING TMR_TASK_DOES_NOT_EXIST for ref_tag: XXXX
like 100+ lines

i looked at the logs and cant see anything saying hung io or an OSD come
out and back in.

does any one have any susgestions on whats going on??


Thanks
