Unusual amount of overhead on large volume group

2008-09-29 Thread Scott Rohling
I'm confused about how much overhead seems to be involved in creating a volume group that approaches a terabyte with ECKD devices (A mix of some 3390-27 and mostly 3390-9): dxxxml01: ~ df -h FilesystemSize Used Avail Use% Mounted on /dev/mapper/sysvg-root

Thanks, Mark -- I forgot all about -m 0 when doing the mkfs.ext3 -- and using tune2fs -m0 got us back to 897G! Scott Rohling On Mon, Sep 29, 2008 at 10:53 AM, Mark Post [EMAIL PROTECTED] wrote: On 9/29/2008 at 12:49 PM, in message [EMAIL PROTECTED], Scott Rohling [EMAIL PROTECTED] wrote:
