Hi Everyone,
My ceph instance was too slow and I tried to benchmark it with bonnie++.
Benchmark finished with error message and Ceph died.
I cannot mount ceph on any computers:
root@s3-2core:~# mount -t ceph -o
name=admin,secretfile=/etc/ceph/mycluster.secret 192.168.2.11:/ /root/mnt/
mount error 5 = Input/output error
I have 250Gb data in ceph, I can generate this data again but it will
take around 2 weeks.
The question how can I reanimate ceph? I like the idea of ceph but
unfortunately I am not alone in the project an we are close to give up
on using it.
I just recently start to use it and don't know what kind of information
I should submit. Here are what I know:
