Date: Tue, 15 May 2007 11:35:57 +0200 From: Tomasz Chmielewski <mangoo@...g.org> To: linux-kernel@...r.kernel.org Subject: what does e2fsck's "non-contiguous" really say? What does e2fsck's "non-contiguous" really say? I always thought it may give a clue about how a filesystem is fragmented. However, I had set up a filesystem on a 365 GB RAID-5 array: /dev/sdao 365G 195M 347G 1% /mnt/1 The filesystem contains only one directory (lost+found). I ran e2fsck on that filesystem, and it says "9.1% non-contiguous": # e2fsck -f part e2fsck 1.39 (29-May-2006) Pass 1: Checking inodes, blocks, and sizes Pass 2: Checking directory structure Pass 3: Checking directory connectivity Pass 4: Checking reference counts Pass 5: Checking group summary information part: 11/48594944 files (9.1% non-contiguous), 1574757/97187200 blocks "9.1% non-contiguous" - what meaning does it really have? -- Tomasz Chmielewski http://wpkg.org - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
