For example assuming 10 drives, drives a-e are in group 1 and drives f-j are in group 2. Using System A with drives a-e connect to /dev/sda-e create a parittion that spans the entire drive for each drive. Create a PV on each partition (/dev/sd[a-e]1). Create a VG named test with all partitions (/dev/sd[a-e]1). Create a <st1:City w:st="on"><st1:place w:st="on">LV</st1:place></st1:City> that covers all of the VG test. Mount the <st1:City w:st="on"><st1:place w:st="on">LV</st1:place></st1:City> and format it (ext3 in this case). Umount and vgexport the vg test. Repeat the steps with drives f-j with same VG and <st1:City w:st="on"><st1:place w:st="on">LV</st1:place></st1:City> names. Connect group 1 to System B and vgimport VG test, create <st1:City w:st="on"><st1:place w:st="on">LV</st1:place></st1:City> with it and mount the filesystem. Umount the filesystem and disconnect group1. Connect group 2 to System B and vgimport VG test and mount the filesystem (using <st1:place w:st="on"><st1:City w:st="on">LV</st1:City></st1:place> previously created)?<o:p></o:p> <o:p> </o:p> Raid is unavailable due to already deployed hardware, and I realize that LVM is not Raid and will not give me a means to recover the data on the failed HDD.<o:p></o:p> <o:p> </o:p> Thanks, Nick<o:p></o:p> </div> <div> This email and any files transmitted with it are confidential and are intended solely for the use of the individual or entity to whom they are addressed.
