topic algorithm for stripe size allocation in Operating System - HP-UX https://community.hpe.com/t5/operating-system-hp-ux/algorithm-for-stripe-size-allocation/m-p/3658351#M620764 Hi,<BR /><BR />As you see the example of LVM kilobyte-stripe following<BR /><BR /># lvcreate -i 24 -I 64 -L 1024 /dev/vgabc <BR /><BR />The stripe size are available to assign like 4,8,16,32,64k up to 32MB.(default 16k)<BR /><BR />Q1) I wonder what is the source or algorithm of determining the value of sequencial stripe size by hp-ux 11i?<BR /><BR />Q2) <BR />from the example, can I make LV 1024MB 64k striping per 24PVs?<BR /><BR />when I tried to do that, couldn't make the size(1024MB)and got a warning mesage "1538MB" I needed for that. why?<BR /><BR /><BR /><BR /><BR />Thanks for advance<BR /><BR />- Kim <BR /> Wed, 26 Oct 2005 12:21:13 GMT KCS_1 2005-10-26T12:21:13Z algorithm for stripe size allocation https://community.hpe.com/t5/operating-system-hp-ux/algorithm-for-stripe-size-allocation/m-p/3658351#M620764 Hi,<BR /><BR />As you see the example of LVM kilobyte-stripe following<BR /><BR /># lvcreate -i 24 -I 64 -L 1024 /dev/vgabc <BR /><BR />The stripe size are available to assign like 4,8,16,32,64k up to 32MB.(default 16k)<BR /><BR />Q1) I wonder what is the source or algorithm of determining the value of sequencial stripe size by hp-ux 11i?<BR /><BR />Q2) <BR />from the example, can I make LV 1024MB 64k striping per 24PVs?<BR /><BR />when I tried to do that, couldn't make the size(1024MB)and got a warning mesage "1538MB" I needed for that. why?<BR /><BR /><BR /><BR /><BR />Thanks for advance<BR /><BR />- Kim <BR /> Wed, 26 Oct 2005 12:21:13 GMT https://community.hpe.com/t5/operating-system-hp-ux/algorithm-for-stripe-size-allocation/m-p/3658351#M620764 KCS_1 2005-10-26T12:21:13Z Re: algorithm for stripe size allocation https://community.hpe.com/t5/operating-system-hp-ux/algorithm-for-stripe-size-allocation/m-p/3658352#M620765 Choosing a stripe size of 64k over 24 volumes means at least 1 stripe has to be allocated on all 24 volumes.<BR /><BR />64 * 24 = 1536 Wed, 26 Oct 2005 12:57:53 GMT https://community.hpe.com/t5/operating-system-hp-ux/algorithm-for-stripe-size-allocation/m-p/3658352#M620765 Pat Lieberg 2005-10-26T12:57:53Z
