Re: crash of osd using cephfs jewel 10.2.2, and corruption

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

 



Looks like the OSD didn't like an error return it got from the
underlying fs.  Can you reproduce with

debug filestore = 20
debug osd = 20
debug ms = 1

on the osd and post the whole log?
