Hello,
![]()
I'm trying to understand the output of the dump_historic_ops admin sock command.
I can't find information on what are the meaning of the different states that an OP can be in.
For example, in the following excerpt:
{
"description": "MOSDPGPush(1.a5 421/239 [PushOp(1:a534ca1b:::rbd_data.cb0f2fd796ae.000000000000317e:head, version: 230'121959, data_included: [20480~4096,40960~4096,102400~4096,110592~4096,122880~4096,147456~4096,266240~4096,274432~4096,434176~4096,593920~4096,65

}
},
Seems like I have an operation that was delayed over 2 seconds in queued_for_pg state.
What does that mean? What was it waiting for?
