Hi guys,
I have got a problem. I created a new 1TB RBD device and mapped in on the
box. I tried to create a file system on that device but it failed:
root@export01:~# mkfs.ext4 /dev/rbd/pool/server1

The funny thing is I tried to change the RBD size to something like 100GB
and it was the same. However when I mapped that RBD on another box file
system creation was successful. When I mapped that back to the export01 box
(with the file system already created) I got:
root@export01:~# fdisk -l /dev/rbd/pool/server1
root@export01:~# dmesg |tail

But on the other box it is working absolutely fine.
Any ideas ?
Thank you.
Regards.
