inode lvm and interface question

1)how do you check how many interfaces your systems has (machine is remotely located)

2) What to do if the root filesystem is out of inode (apart from deleting files )

3) Is it possible to increase a root filesystem if created under LVM if yes how?

Thanks you.

1) ifconfig -a will show you all the interfaces that have been correctly detected by the kernel

2) You have two options
- Quick Fix = Grow the LVM but you only increase the number of inodes by the amount of new filesystem you add, so you will always be short.
- Proper Fix - Recreate the LVM (in other words mkfs)
You could boot from a rescue disk and create a new LVM then mirror it and the break it and the destroy the old LVM, updating your boot configuration and not forgetting to do a backup !

3) Yes you can do it on line.
- See ext2online for growing the filesystem
- and lvextend -L {size} mountpoint
lvextend -L +5G /dev/OSvg/ROOT which will extend the ROOT volume on the Volume group OSvg by 5G.

- Remember to grow the LVM first then grow the filesystem.

Hope that helps let me know how u go.

The might be a few alternatives as what I was proposing would take a fair time and rely upon you having the same amount of free space that the root volume has and would not be easy to, it would be easy to screw it up and loss the lot.
The Question is why have you run out of Inodes, I assume it was a standard installtion and that you did not customize the filesystem (which you can do when you create the filesystem by hand)
Normally Inodes will fill up because you have lots of little files (each file requires an Inode), therefore running out of inodes first but leaving you with plenty of free space.
You could locate the these small files and create a new filesystem with additional inodes using the mkfs command and the move the files to the new filesystem. Or alternativly backup your important data and re-install.
Normally best practice suggest that you have a sperate / /var /home, and then also create other filesystems for your data / users etc.
