Subject: os/FileStore: print error to log on eio
X-Git-Tag: v10.0.4~128^2
X-Git-Url: http://git-server-git.apps.pok.os.sepia.ceph.com/?a=commitdiff_plain;h=c69a2aace459a4d07f1088b08679bac4a6e43f72;p=ceph.git

os/FileStore: print error to log on eio

when osd do backfillings, once read one file failed
osd will assert failed, and never up again.
so we need locate this file from log at level-0,
delete it manully,start osd and let backfill go again.
