Ok, now more seriously:<\/p>\n<p>&nbsp;<\/p>\n<p>* From the very beginning this FS is target for multi-core, multi-threaded disk operations\u00a0= extremely good transfer rate (including concurrent), mature, quick file system designed for pure performance.<\/p>\n<p>* Fast (=delayed :-D) allocation (by extents) &#8211; very useful with daily work with virtualization tools and spending hundreds of GB. It\u00b4s connected with online defragmentation.<\/p>\n<p>* <a href=\"http:\/\/linux.die.net\/man\/8\/xfs_fsr\">xfs_fsr<\/a>, <a href=\"http:\/\/linux.die.net\/man\/8\/xfs_repair\">xfs_repair<\/a> and other <a href=\"http:\/\/www.linuxfromscratch.org\/blfs\/view\/svn\/postlfs\/xfsprogs.html\">xfs utility<\/a>.<\/p>\n<p>* Supporting TRIM and option for place journal into another disk.<\/p>\n<p>* fsck (point of many criticism within XFS) is placed into connecting device = no more 30th start of system or period of time.<\/p>\n<p>* Data security &#8211; I\u00b4m maybe unusual user, but xfs_check is scheduled, any repair\/restore\/partition copy was done without any issues. Again &#8211; I\u00b4m just BFU testing these features in my environment.<\/p>\n<p>* Exceptional performance while using ANY database and ANY virtualization solution. Simply &#8211; if your work consist of creating more or less big files, XFS is dominating.<\/p>\n<p>-a-<\/p>\n","protected":false},"excerpt":{"rendered":"<p>I must admit I\u00b4m really conservative person in many ways.
