So each pv wll be 1TB (12 TB / 12 partitoins per above), hence each vg and lv will initially be 1TB. As the FS grows on an lv, we'd add another 1TB PV. |What blocksize are you using? Default - how does it matter in terms of the errors? The first few times I built everything it worked fine. Now when I create the partitions and try to make each one a PV, some fail as above. If I nuke them and start over, I get more failures-- maybe the same ones fail the same way, maybe not. Somewhere a config or resource has gotten corrupt, but for the life of me I can't find it. |What research have you done? I've gone through a half dozen docs on the web to set things up. I googled for the error messages, but couldn't find anything useful.
