We are getting alerts from UM about volumes running low on inodes. We have volumes that have 10's of millions of documents and we generally just increase the inode count by 20% in proportion to the volume size. Earlier this month, my co-worker called Netapp support and asked for guidance on this same exact thing. He was told the following:
increasing the iNode count should be option #2, whereas option #1 would be to create a new volume and/or move data off of the volume. With that said, increasing the iNode count is supported, and it is OK to increase the iNode count 2 times, by 20% each time.
Have any of you have had issues increasing inode count more than twice. Anyone know why option 2 which is increasing inodes is not recommended.
