Wondering if anyone has any comments.<div><br></div><div>A home system has N number of 1.5TB drives, running in RAID5.</div><div>At one point, these drives stopped becoming available, so the last time I extended the array, I used a 2TB drive.</div>
<div><br></div><div>That drive is formatted with:</div><div><br></div><div><div>/dev/sdg1            2048   976735943   488366948   8e  Linux LVM</div><div>/dev/sdg2       976735944  3907029160  1465146608+  fd  Linux RAID autodetect</div>
</div><div><br></div><div>The LVM system in question holds my root/home, etc.</div><div><br></div><div>Now that a 1.5TB drive has failed, I&#39;m replacing it with another 2TB drive, and wondering the best way to use the remainder 500GB</div>
<div>My first thought is to set up a RAID1 array, and put my PV on there.</div><div>Is there a better plan?</div><div>Are there going to be any issues, such as booting?</div><div>I presume grub2 will be fine, and will just add an &#39;insmod raid&#39; before the &#39;insmod lvm&#39; line in my grub.cfg</div>
<div><br></div><div>As for the procedure, my vague plan is:</div><div><br></div><div>sfdisk -d /dev/sdg | sfdisk /dev/sdh</div><div>mdadm --create /dev/md1 --level=1 --raid-devices=2 /dev/sdh1 missing</div><div>pvcreate /dev/md1</div>
<div>vgextend system /dev/md1</div><div>pvmove -v /dev/sdg1</div><div>pvremove /dev/sdg1</div><div>mdadm --manage /dev/md1 --add /dev/sdg1</div><div><br></div><div>mount /, chroot into it, run grub-install</div><div><br></div>
<div>Can anyone see any flaws in logic, places to improve?</div><div><br></div><div>cheers,</div><div><br></div><div>     / Brett</div>
