Apple yesterday released Xsan Update 1.0.1 which delivers overall improved reliability for Xsan and is recommended for all systems. It includes improvements for:
– using the ‘mv’ command to move files from Xsan (ACFS) to Mac OS Extended (HFS+) volumes
– saving files over 4GB via SMB/CIFS to an Xsan volume hosted on Mac OS X Server
– greater server stability when resharing Xsan volumes via NFS
– eliminating spontaneous metadata controller failovers that can result in slow file performance
