I have a machine at a datacenter with 3HDDs and running Debian Wheezy, at one of them I have an ext4 filesystem mounted on /data that has ran out of inodes (I've chosen an inappropriate inode size at install/had more tiny files than expected).
There's no problem in copying the partition content to another one, but I want to know which preventive measures should I have to do this process in a "production environment" (nothing serious btw).
I need to avoid rebooting the machine and make the new filesystem -recreated- mountable at boot
Thanks! -Rodrigo
