Guys , thanks much for your time on the issue, really appreciate it . I had tried everything suggested so far (lvresize/extend) updated filesystem tools etc
@Stuart D Gathman , YOU ARE THE MAN SIR :) and nailed it down .
I wanted to reproduce the same issue again and i did that not know how ignorant I was being ..
# lvextend -L +40G /dev/vg0/bin-logs
Extending logical volume bin-logs to 110.00 GB
Logical volume bin-logs successfully resized

LV VG Attr LSize Origin Snap% Move Log Copy% Convert
bin-logs vg0 -wi-ao 110.00G

resize2fs /dev/vg0/bin-logs
resize2fs 1.39 (29-May-2006)
resize2fs: Filesystem has unsupported feature(s) while trying to open /dev/vg0/bin-logs
Couldn't find valid filesystem superblock.
#this is where I would get psyched , i did the same thing to all my ext2/3 filesystems and have extended file systems online without an issue for years ..but did I fforget the file system type this time , yes indeed I for got we have started doing ext4 on all our new servers and didn't realise ext4 fancies it's own bells and whistles ..
I ran the all new resize4fs as suggested by Stuart , and it made my day in fact it made for the whole week's frustration :)
resize4fs /dev/vg0/logs
resize4fs 1.41.12 (17-May-2010)
Filesystem at /dev/vg0/logs is mounted on /bin-logs; on-line resizing required
old desc_blocks = 7, new_desc_blocks = 9
Performing an on-line resize of /dev/vg0/logs to 37408768 (4k) blocks.
The filesystem on /dev/vg0/logs is now 37408768 blocks long.

PS: I am raving fan of lvm all over again :)
thanks everyone and issue closed !

The resize2fs on RHEL5 does not support ext4. Your error message is the one reported when you try to resize an ext4 filesystem with ext2/ext3 tools. You need to either install e4fsprogrs and use resize4fs (and e4fsck), or do the resize in the virtual machine you are apparently running a newer OS in.On 08/23/2012 11:18 AM, tariq wali wrote:
lvresize to extend an lvm ? how
also I cant create a new lvm don't have that much space and the to extend the new one and it would mean downtime . don't think it's an issue with filesystem tools , lvm has NEVER been consistent in my case .
