boot - unsure where to install grub on hardware RAID10 after upgrading ubuntu 14.04 - Ask Ubuntu


after upgrading packages on ubuntu 14.04 system, grub-pc configuration tool asks me install grub.

  • /dev/sda (500107 mb; st9500530ns)
  • /dev/sdb (500107 mb; st9500530ns)
  • /dev/sdc (500107 mb; st9500620ns)
  • /dev/sdd (500107 mb; st9500530ns)
  • /dev/sde (500107 mb; st9500530ns)
  • /dev/dm-0 (1973860 mb; data1--vg-root)

i did not configure server, know has hardware raid configuration.

where should grub installed?

based on comments:

sudo pvs [sudo] password coen: pv         vg       fmt  attr psize   pfree /dev/sda5  pindi-vg lvm2 a--  697.88g 45.96g

and

for szdisk in $(ls /dev/sd?); echo "$szdisk"; dd if="$                      szdisk" bs=1 count=4 skip=392; done  /dev/sda grub4+0 records in 4+0 records out 4 bytes (4 b) copied, 0.0139631 s, 0.3 kb/s

i think suggests should choose /dev/sda install grub ?
