A useful tool I came across last night (thanks Rodrigo) – sfdisk – “Partition table manipulator for Linux”.
Good for copying partition tables when replacing a failed hard disk in a (md Linux Software Raid) RAID. For example, to copy the partition table from sdb to sda:
sfdisk –d /dev/sdb | sed –e s/sdb/sda/ | sfdisk /dev/sda
Of course you’d also be doing the usual **mdadm –fail, –remove, physically swap disk, –add, cat /proc/mdstat, –detail, **and installing grub on the new hard drive:
grub> device (hd0) /dev/sdb grub> root (hd0,0) grub> setup (hd0) grub> quit
(Unmercifully plagiarised from Rodrigo’s notes).comments powered by Disqus
