Hello, I'm running afr on two storage servers, with three clients. For the moment, we have copied over 500 million small files on it, splitting into each directory which contains 1000 files. When doing ls in directory containing 1000 directory's we have the following issue: - Ls is taking more then 15 minutes to complete in a directory with 1000 folders. (this will be split also to 100 folders later, but it's now a big problem) -> Yes, for now its ls --color=auto by default on debian :D - When doing copies from other clients, those copies halt until that ls is complete. Is there a way to 1) Do a ls faster (ok, I know it can be that fast like on the filesystem itself, but on the filesystem (or an nfs system) it takes max 15 seconds) 2) When someone is doing an ls, the other processes are not freesing. (checking on the storage servers, we have a load of 0.00) The filesystems we use are based on xfs. An example of a server config: volume sas-ds type storage/posix option directory /sas/data end-volume volume sas-ns type storage/posix option directory /sas/ns end-volume volume sata-ds type storage/posix option directory /sata/data end-volume volume sata-ns type storage/posix option directory /sata/ns end-volume volume sas-backup-ds type protocol/client option transport-type tcp/client option remote-host x.x.x.x option remote-subvolume sas-ds end-volume volume sas-backup-ns type protocol/client option transport-type tcp/client option remote-host x.x.x.x option remote-subvolume sas-ns end-volume ... volume sas-unify type cluster/unify subvolumes sas-ds-afr option namespace sas-ns-afr option scheduler rr end-volume volume sata-unify type cluster/unify subvolumes sata-ds-afr option namespace sata-ns-afr option scheduler rr end-volume volume sas type performance/io-threads option thread-count 16 option cache-size 256MB subvolumes sas-unify end-volume volume sata type performance/io-threads option thread-count 16 option cache-size 256MB subvolumes sata-unify end-volume .. I hope to fix this, because we want to double this next year :) Regards, Tom
