resize2fs on LVM on MD raid on Fedora Core 3 - inode table conflicts in fsck
Hi.
I'm attempting to setup a box here to be a file-server for all my data.
I'm attempting to resize an ext3 partition to demonstrate this
capability to myself before fully committing to this system as the
primary data storage. I'm having some problems resizing an ext3
filesystem after I've resized the underlying logical volume. Following
the ext3 resize, fsck spits out lots of errors like:
Pass 1: Checking inodes, blocks, and sizes
Group 49's inode table at 1605636 conflicts with some other fs block.
Relocate<y>? no
I believe that I'm following the correct procedure for resizing the
filesystem. Any pointers greatly appreciated. Thanks.
A complete transcript demonstrating this problem follows:

It seems that resize2fs isn't taking these reserved blocks into account when it is allocating the inode table.> root at SEVERN:~# e2fsck -f /dev/severn_vg0/test > e2fsck 1.35 (28-Feb-2004) > Pass 1: Checking inodes, blocks, and sizes > Group 49's inode table at 1605636 conflicts with some other fs block. > Relocate<y>? no > > Group 1: block bitmap at 33089, inode bitmap at 33090, inode table at > 33091 > 31933 free blocks, 16384 free inodes, 0 used directories > Group 3: block bitmap at 98625, inode bitmap at 98626, inode table at > 98627 > 31933 free blocks, 16384 free inodes, 0 used directories > Group 5: block bitmap at 164161, inode bitmap at 164162, inode table > at 164163 > 31933 free blocks, 16384 free inodes, 0 used directories > Group 7: block bitmap at 229697, inode bitmap at 229698, inode table > at 229699 > 31933 free blocks, 16384 free inodes, 0 used directoriesAll of these groups have backup group descriptors, as do all groups numbered {3,5,7}^n. Note free blocks count.> Group 49: block bitmap at 1605634, inode bitmap at 1605635, inode > table at 1605636 > 32252 free blocks, 16384 free inodes, 0 used directoriesThis is the first group with backup descriptors created by resize2fs. It doesn't have the reserved group blocks (about 300 or so) and e2fsck is likely complaining about this. This is obviously a bug that needs to be fixed. The good news is that instead of resizing your filesystem while it is unmounted you can resize it while it is mounted, and that shouldn't suffer from any of these problems (and is much more convenient). You need the ext2resize RPM from sourceforge (don't know why it isn't in FC2 if they have also applied the patch to mke2fs): ftp://rpmfind.net/linux/sourceforge/e/ex/ext2resize/ext2resize-1.1.19-1.i386.rpm Then you can mke2fs a new filesystem, mount it, lvextend, and run "ext2online /dev/severn_vg0/test" and it will grow to fill the LV. There is also a tool that ships with LVM called "e2fsadm" which does this for you, like "e2fsadm -L +5G /dev/severn_vg0/test" should do both the lvextend and ext2online step at once. You should also be able to properly resize it while unmounted with ext2resize, but that is far less interesting...
