On the data partition I had 86G free that I needed to use elsewhere.
All the following have been done from a recovery disk so the data is all still intact.
When I tried to resize to 400G it wouldn't let me stating below mjnimum size...
sudo resize2fs -p /dev/pathto/lvmdevice 400G
However mounting it df -h reports
Size Used Free
/dev/pathto/lvmdevice 487G 377G 86G
or in 4k blocks
/dev/pathto/lvmdevice 127571672 98643758 22449438
So I was forced to run the resize2fs in tye default 4k mode
sudo resize2fs -p /dev/pathto/lvmdevice 105000000
This should give me a sufficient overhead and finished correctly
I then did
sudo lvresize -L /dev/pathto/lvmdevice
This also appeared to be successful.
However I can't mount it as it's reporting wrong fs type, bad option etc error.
I think I've identified the problem as a mismatch on ghe block count.
Even though I resized to 105000000 blocks I now see that df -h reported the size as 103352144 before I did the lvresize (I didn't notice at the time)
So I think the discrepancy between the block count size reported by df at 103352144 and tune2fs at 105000000 is the error.
How can I change the block count number reported by tune2fs from 105000000 to 103352144 that will then allow me to run e2fsck again?
Thanks
