It seems that what is wrong with my 'flakey' drive is not that it has bad sectors, but that it has a tendency to heat up when used, and then fail all operations until its cooled down. So, I went out and managed to borrow a sata card for my server so that I could hook up all five drives at once, and actually have an active system while working on it, and now I would like to pvmove all of the PE's from the old flakey drive to the replacement. pvmove typically reports getting somewhere around 7% done before the drive fails, but I would like to know what that represents in terms of checkpointed data. The man pages are frustratingly vague on a large number of points: 1) how do you get a list of PEs on a PV? 2) how often are checkpoints made, and can you control that in any way? 3) can you request a given number of PEs to be moved? (I googled and found someone who claimed to do that in a similar situation, but I could find no further details). 4) the man page for pvmove says that you can reference a physical volume with PhysicalVolume[:PE[-PE]..., but it doesn't say what those suffixes mean, nor could I find any man page which explained it. Basically, I want to attempt to optimize my uses of pvmove to transfer as much as possible in as few attempts as possible. Any help would be appreciated. -- Stirling Westrup Programmer, Entrepreneur. https://www.linkedin.com/e/fpf/77228 http://www.linkedin.com/in/swestrup http://technaut.livejournal.com _______________________________________________ linux-lvm mailing list linux-lvm@redhat.com https://www.redhat.com/mailman/listinfo/linux-lvm read the LVM HOW-TO at http://tldp.org/HOWTO/LVM-HOWTO/
