Hi All, Trying to run fsck on a local linux raid partition gave the following. [root at ... /]# fsck.ext4 /dev/md0 e2fsck 1.41.12 (17-May-2010) /dev/md0 has unsupported feature(s): 64bit e2fsck: Get a newer version of e2fsck! Odd as the server is 64bit running latest kernel and using latest "e2fsprogs.x86_64". Any ideas awould be much appreciated. Cheers Steve k
