Re: [linux-lvm] Pvmove fails... No free PE's (and lvextend does not work...)



I currently use RedHat 7.2 with kernel 2.4.18-4, but I have tested most kernel versions from 2.4.16. I am also using lvm 1.0.1.

I have tried to move all extents and just a few (or even one) extents with no luck... Could it be that this disk is 120GB (114,44) and there would be some problems with that?
