Apple has posted Xsan Update 1.0.1, the first update to its enterprise-class storage networking solution. Version 1.0.1 “delivers overall improved reliability for Xsan and is recommended for all systems,” according to the release notes. 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; and eliminating spontaneous metadata controller failovers that can result in slow file performance.
