Hi all,
I have a development box I am playing around with lvm on. I had
successfully extended a VG using e2fsadm.
Command was:
e2fsadm -L+24G /dev/vg1/lvol1
I then wanted to reduce it by the same amount:
drsvr02:/root# e2fsadm -L-24G /dev/vg1/lvol1
e2fsck 1.32 (09-Nov-2002)
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
/dev/vg1/lvol1: 818050/11960320 files (13.1% non-contiguous),
15412825/23920640 blocks

Begin pass 4 (max = 37732)
Updating inode references XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXThe
filesystem on /dev/vg1/lvol1 is now 17629184 blocks long.
lvreduce -- WARNING: reducing active logical volume to 67.25 GB
lvreduce -- THIS MAY DESTROY YOUR DATA (filesystem etc.)
lvreduce -- ERROR "No such device or address" reducing logical volume
"/dev/vg1/lvol1" in kernel
After the error, I tried to e2fsck and even mount, but:
drsvr02:/root# e2fsck /dev/vg1/lvol1
e2fsck 1.32 (09-Nov-2002)
e2fsck: Attempt to read block from filesystem resulted in short read while
trying to open /dev/vg1/lvol1
Could this be a zero-length partition?
drsvr02:/root# mount /mail
mount: wrong fs type, bad option, bad superblock on /dev/vg1/lvol1,
or too many mounted file systems
Vgdisplay still gives me the following:
drsvr02:/root# vgdisplay
--- Volume group ---
VG Name vg1
VG Access read/write
VG Status available/resizable
VG # 0
MAX LV 256
Cur LV 1

MAX LV Size 2 TB
Max PV 256
Cur PV 2
Act PV 2
VG Size 92.19 GB
PE Size 32 MB
Total PE 2950
Alloc PE / Size 2152 / 67.25 GB
Free PE / Size 798 / 24.94 GB
VG UUID g4xXEb-TpOU-TNBM-TZSc-fbIm-NPw4-wHKrkM
Is there any recovery possibility? Or how do I go about blowing everything
away and starting over?
Thanks for any help,
Diane
