[gpfsug-discuss] Inode reuse on AFM cache eviction

[Venkateswara R Puvvada]

Hi,

AFM does not support inode eviction, only data blocks are evicted and the 
file's metadata will remain in the fileset.

eviction

Hi,
Does anyone here know if cache eviction on a AFM cache also make the 
inodes used by the evicted files available for reuse?
Basically, I'm trying to figure out if it is enough to have sufficient 
inode space in my cache filesets to keep the maximum expected 
simultaneously cached files, or if I need the same inode space as for the 
total amount of files that will reside in the home of the cache. 

Regards,
Andreas Mattsson
