Simple concept: Each 4K block is 1 node. lets say you have 1TB volume, the number of inodes you can have is: (1024 * 1024 *1024)/4= 268435456 inodes. The best practice is use upto 75 to 85% of nodes of a volume. If you further need the inodes, you better increase the size of the volume and increase the inodes after the threshold is reached (85% inodes consumption).
First 1024 is GB and second 1024 is mb and third 1024 is KB - This is just a note.
Hii scott, I have a question..In my earlier company we went till 95% aggr capacity and we dint go beyond that. In my new one, they are saying we cant go beyond 85% which affects performance. Is this true..If not whats the best practice..Does it depend on disk types?.
Thanks guys...So all our aggregates on a box reached 85%, and a new volume has to be created, I cant delete snapshots as they are important, I cant add more disks as there are only two spares left..i reduced snap reserve to 0% on aggregate already..i cant reduce inode count too as it is already 92%...Does reducing the quota limits on the qtres will provide space on aggregate as our volumes are thick provisioned…so now what am I supposed to do other than putting that volume on other storage box.
