Hi, I've seen that EXT4 has better random I/O performance than XFS, especially on small reads and writes. For large sequential reads and writes XFS is a little bit better. For really large sequential reads and write EXT4 and XFS are about the same. I used to format XFS using this: mkfs.xfs -l size=64m (notes from http://everything2.com/title/Filesystem+performance+tweaking+with+XFS+on+Linux) but realized that it doesn't seem to effect performance for me. You should definitely try mounting with this : mount -t xfs -o rw,noatime,nodiratime,logbufs=8 HTH, Sabuj On Thu, Oct 20, 2011 at 8:18 AM, Gerald Brandt <gbr at majentis.com> wrote: > Hi, > > Are there any 'optimal' settings for XFS formatting under GlusterFS? ?The storage will be used for Virtual Disk storage, virtual disk size from 8GB to 100 GB in size. > > One of the VM's (separate gluster volume) will be running MSSQL server (4K reads and writes). ?The other will be running file servers, etc). > > Thanks, > Gerald > _______________________________________________ > Gluster-users mailing list > Gluster-users at gluster.org > http://gluster.org/cgi-bin/mailman/listinfo/gluster-users >
