Hello Frederik,
Just some addition, maybe its of interest to someone: The number of max open
files for Ganesha is based on maxFilesToCache. Its. 80%of maxFilesToCache up to

NFSv3 doesn't have open/close requests, so nfs-ganesha opens a file for
read/write when there is an NFSv3 read/write request. It does cache file
descriptors, so its open count can b
Hello Frederik,
Thank you. I now see a similar behavior: Ganesha has 500k open files while the

We have some issues with ganesha (on spectrum scale protocol nodes) reporting
NFS3ERR_IO in the log. I noticed that the affected nodes have a large number of
Heiner,
we are seeing similar issues with CES/ganesha NFS, in our case it
exclusively with NFSv3 clients.
What is maxFilesToCache set to on your ganesha node(s)? In our case
ganesha was running into the limit of open file descriptors because
maxFilesToCache was set at a low default and for
