If i remove ( or shutdown ) this OSD, it's can solved my problem ?You want to figure out why they're inconsistent (if they're still going inconsistent, or maybe just need to be repaired), but this shouldn't be causing your MDS troubles. Can you dump the MDS journal and put it somewhere accessible? (You can use ceph-post-file to upload it.) John has been trying to reproduce this crash but hasn't succeeded yet. -Greg Software Engineer #42 @ http://inktank.com | http://ceph.com
Hi, I try to do :cephfs-journal-tool journal export ceph-journal.bin 2> cephfs-journal-tool.log
But the program crash. I upload log file : e069c6ac-3cb4-4a52-8950-da7c600e2b01
There is a mistake in http://ceph.com/docs/master/cephfs/cephfs-journal-tool/ in "Example: journal inspect". The good syntax seems to be :
# cephfs-journal-tool journal inspect2014-07-17 00:54:14.155382 7ff89d239780 -1 Header is invalid (inconsistent offsets)
Overall journal integrity: DAMAGED Header could not be decoded Regards -- ---------------------------------------------- Pierre BLONDEAU Administrateur Systèmes & réseaux Université de Caen Laboratoire GREYC, Département d'informatique tel : 02 31 56 75 42 bureau : Campus 2, Science 3, 406 ----------------------------------------------
