Is this really, possibly, wonderfully true??!! Which version of ONTAP fixed this? The reason I ask is that on all our filers (mostly F760 and some F840's), the total number of folders at any one directory level was a function of the inode limit of a 2 bit, unsigned pointer - thus limited it to just under 65k directories at any one level. Since we have 9.5 million user directories spread across those filers, we had to write scripts to check when that threshold was being reached to create a new one.
9.5 million!!! Jeepers.
A quick sh script verifies 2^16 - 1 directory entries are possible, no more:
mkdir: Failed to make directory "65533"; Too many links
(0-65532 directories, plus "." and ".." equals 65,535)
It's exactly linear; every 128 entries, the size of the directory grows by 4,096 bytes. Cool. Linearity is good, and predictable.
Until next time...
