Does anyone know which to believe, 116Gb or 24Gb is free? I have diagnostic details appended below. Also, if the volume was created with logvol() (see #4) with the maxsize parameter used, does that affect later growth of the file system beyond maxsize (see #3)? My superficial understanding of inodes and blocks does not extend to lvm() and how that affects creation-time parameters shown by tune2fs. Thanks in advance, Van Ly -- # 1 # this comes close to 116Gb free <- `Available: 30246714` # stat -f /common File: "/common" ID: 0 Namelen: 255 Type: ext2/ext3 Block size: 4096 Fundamental block size: 4096 Blocks: Total: 60944400 Free: 33391866 Available: 30246714 Inodes: Total: 62914560 Free: 62037005 # 2 # free blocks suggests there is 24Gb free tune2fs 1.39 (29-May-2006) Filesystem volume name: <none> Last mounted on: <not available> Filesystem UUID: b78a127a-80d9-43e2-8f9c-143a82137eb8 Filesystem magic number: 0xEF53 Filesystem revision #: 1 (dynamic) Filesystem features: has_journal ext_attr resize_inode dir_index filetype needs_re\ covery sparse_super large_file Default mount options: user_xattr acl Filesystem state: clean Errors behavior: Continue Filesystem OS type: Linux Inode count: 62914560 Block count: 62914560 Reserved block count: 3145152 Free blocks: 6417762 Free inodes: 15443849 First block: 0 Block size: 4096 Fragment size: 4096 Reserved GDT blocks: 1009 Blocks per group: 32768 Fragments per group: 32768 Inodes per group: 32768 Inode blocks per group: 1024 Filesystem created: Thu Dec 18 12:06:47 2008 Last mount time: Sun Feb 1 07:25:25 2009 Last write time: Sun Feb 1 07:25:25 2009 Mount count: 3 Maximum mount count: -1 Last checked: Thu Dec 18 12:06:47 2008 Check interval: 0 (<none>) Reserved blocks uid: 0 (user root) Reserved blocks gid: 0 (group root) First inode: 11 Inode size: 128 Journal inode: 8 First orphan inode: 30212898 Default directory hash: tea Directory Hash Seed: 15dea504-b626-476b-8513-fdc11b43abaf Journal backup: inode blocks # 3 # volume has since been grown to 233Gb # df -h /common Filesystem Size Used Avail Use% Mounted on /dev/mapper/vg0-commonlv 233G 105G 116G 48% /common # 4 # redhat kickstart created volume logvol /common --fstype ext3 --name=commonlv --vgname=vg0 --size=512 --grow --maxsize=61440 </BODY> </HTML>
