Hi,
due a harware failure during expanding ceph, I'm in big trouble
because the cephfs doesn't mount anymore.
I was adding a couple storage nodes, but a disk has failed and after a
reboot the OS (ubuntu 12.04) renamed the remaining devices, so the
entire node has been screwed out.
Now, from the "sane new node", I'm taking some new osd up and in
because the cluster is near full and I can't revert completely the
situation as before
*I can* afford data loss, but i need to regain access to the filesystem
My setup:
3 mon + 3 mds
4 storage nodes (i was adding no. 5 and 6)
Ceph 0.56.4
