[linux-lvm] LVM Problems :)

[Heinz Mauelshagen]

Christian,

the size of your filesystem and logical volume differs already.
That's why e2fsadm fails.
Did you eventually run resize2fs in order to shrink the filesystem ?

Your logical volume size is 1091456MB (32MB/PE * 34108 PE) but your
filesystem size is 963584GB (941GB * 1024MB/GB; check with
"tune2fs -l" and look for the block count and block size to calculate
this correctly).

In case the result shows, that your filesystem is already smaller than the LV,
lvreduce the logical volume appropriately.

Use the block count * block size result and round it up to the next PE!

Regards,
Heinz    -- The LVM Guy --

*** Software bugs are stupid.
    Nevertheless it needs not so stupid people to solve them ***
