Hi Peter, I've always been under the impression that this is a ball park figure that changes some of the on disk data structures to help parallel access to the filesystem I try to estimate the number of clients and then add ~10% (depending on the cluster size ofc). I have tested the default 3

Loic, mmafmctl prefecth expects encoded list file, and it is not documented correctly. Issues like memory leak, file descriptor leak, and fileset going into Unmounted state were fixed in later releases (4.2.1/4.2.2). All your points are correct with respect to AFM migration. There is manual i

2016-10-24 Thread Eric Horst
The recent conversation about AFM has been interesting. I've read the documentation several times and this is my question. Can AFM be used to migrate between two filesystems in the same cluster? There are examples of moving between clusters with NFS or native protocol but I've got a simple situatio

Yes you can use AFM to move data within a cluster. If you are using the NSD protocol the target needs to be a separate file system, if you are using NFS it needs to be an NFS export. Scott Fadden Spectrum Scale - Technical Marketing Phone: (503) 880-5833 sfad...@us.ibm.com http://www.ibm.com

Loic, It is good to hear that migration is completed. Did you find any prefetch errors in mmfs.log for the files which are different between cache and home ? Not all errors are logged, there is a plan to generate the list of read failed file names after prefetch completion. Informaion about fi
