Hello,
We had a power failure and after some trouble 2 of our OSDs started crashing
with this error:
"FAILED assert(last_e.version.version < e.version.version)"
I know what's the problematic PG, and searching the ceph lists and the web I
saw that ultimately I should fix that PG using ceph-kvstore-tool, but I can't
find an example of how to use it.
Can anybody give me a hint?
Should I ask in ceph-devel?
Thanks in advance.
An extract from a debug log, can provide more if needed:
