Hi,
On a 0.80.7 cluster I'm experiencing a couple of OSDs refusing to start
due to a crash they encounter when reading the PGLog.
A snippet of the log:

The backing XFS filesystem seems to be OK, but isn't this a leveldb
issue where the omap information is stored?
Anyone seen this before? I have about 5 OSDs (out of the 336) which are
showing this problem when booting.
