Hi,
I have a problem starting a couple of OSDs because of the journal being
corrupt. Is there any way to replace the journal and keeping the rest of the
OSD intact.
-1> 2015-01-11 16:02:54.475138 7fb32df86900 -1 journal Unable to read past
sequence 8188178 but header indicates the journal has committed up through
8188206, journal is corrupt
0> 2015-01-11 16:02:54.479296 7fb32df86900 -1 os/FileJournal.cc: In
function 'bool FileJournal::read_entry(ceph::bufferlist&, uint64_t&, bool*)'
thread 7fb32df86900 time 2015-01-11 16:02:54.475276
os/FileJournal.cc: 1693: FAILED assert(0)
I ended up in this situation when osd.9 on host "orange" went down, and then I
had a powerfailure on the host "purple" which made 2 of my journals corrupt.
-3 6 host purple
4 1 osd.4 up 1
5 1 osd.5 down 0
7 2 osd.7 down 0
6 2 osd.6 up 1
-4 6 host orange
8 1 osd.8 up 1
9 1 osd.9 down 0
The filesystem was not in use by users, but it was replicating when the host
went down and I figure that I still have the data on the OSD-disks, they are
still mountable and the XFS-filesystem on them seems to be intact.
Thanks,
Claes
