Re: OSD suicide

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]



Hello Wido,

Yesterday I built from git: $ ceph -v
ceph version 0.44.1-149-ge80126e
(commit:e80126ea689e9a972fbf09e8848fc4a2ade13c59)

The messages are a bit different but the problem seems to be the same.
Below is a part of the osd.48.log. Should I turn debug osd mode more
verbose or give any other information?

Regards,
Vladimir.
