Need help with increasing inodes
So I have an unmanaged dedicated with a 1TB hard drive. I have recently hit the inodes limit. After looking through google it seems the only fix is to reformat the drive with a higher inodes limit.
What I haven't been able to find through google is exactly how to do this and what impact a higher inode limit has. Why doesn't the drive format with a higher inode limit by default?
Here's the info,
System is Centos 6.5 with ext4
Filesystem Inodes IUsed IFree IUse% Mounted on
3276800 58534 3218266 2% /
tmpfs 3074543 1 3074542 1% /dev/shm
/dev/sda1 128016 44 127972 1% /boot
56967168 52227992 4739176 92% /home
I'd really appreciate it if someone could walk me through doing this with the least amount of downtime possible. The server isn't mission critical, however I do run websites on it that provide income. Can I reformat just the /home directory since it's a logical volume to increase the inodes? How many inodes should I set and will it decrease performance or something?
