The problem was that when i created the lvm volume i've used: lvcreate -L 6.75G -n vol1 infrac
with that line, the volume was created linear by default, so i've removed the volume and re-created it with: lvcreate -i3 -I4 -L 6.75G -n vol1 infrac the problem now is that, with linear mode, i've 25-30% utilization with ONE volume only, and now i have 10% utilization in the three devices. thanks On Thu, 27 Nov 2003, John Summerfield wrote: > On Wed, 26 Nov 2003, Alejandro Leyva Rabinovich wrote: > > > Date: Wed, 26 Nov 2003 12:57:53 -0600 > > From: Alejandro Leyva Rabinovich <[EMAIL PROTECTED]> > > Reply-To: Linux on 390 Port <[EMAIL PROTECTED]> > > To: [EMAIL PROTECTED] > > Subject: Re: postgres + lvm + i/o rate > > > > i've created it following the information from > > http://publib-b.boulder.ibm.com/Redbooks.nsf/RedbookAbstracts/tips0128.html?Open > > > > I never trust answers like that.
