Description

when I mounted ceph-fuse, I setted the flag of '--localize-reads'. I found during the test that read_num count was Inaccurate,the local_read was not counted.

History

when set the flag of '--localize-reads', maybe peer_pg will complete read task, but peer_pg will not count read_num. the count will be modify when the Primary_pg writing

#2 Updated by Greg Farnum almost 5 years ago

  • Project changed from Ceph to RADOS
  • Subject changed from pg stats count error when the fuse flag '--localize-reads' was setted to localize-reads does not increment pg stats read count
  • Category deleted (OSD)

Yeah, localize_reads has some issues. This is the least of them and would be hard to fix in the current architecture since non-primary OSDs don't have any write ability.
