My ‘system disk’ (\/dev\/sda) started to show bad sectors, recently, and so I decided to replace it.\u00a0\u00a0\u00a0 The disk was around 8 years old, and had been in almost-continuous use..<\/p>\n
I have not had to do this for some considerable time, and I think the last time was in the late-90s, and using LILO!\u00a0 (No convoluted grub2 commands and UUIDs back then..)<\/p>\n
I found – after some trials – that one successful way of doing this is mentioned in an article here, and thanks to Arif<\/strong><\/em> for the information:\u00a0\u00a0\u00a0 https:\/\/ask.fedoraproject.org\/en\/question\/31666\/how-do-you-install-grub2-on-a-replacement-hard-drive\/<\/a><\/p>\n I created a (Fedora 23) netinst image on a USB stick, and booted from this, and ran the ‘rescue’ utility…\u00a0\u00a0\u00a0 The system only had a USB2 connection, so the utility was very sluggish, but I found that I could get a command prompt by typing alt\/tab<\/em>.. I mounted the ‘new’ root partition (\/dev\/sda2) under \/mnt\/sysimage (\/run\/media\/liveuser\/newdiskroot in the example), and mounted the (separate) boot partition (\/dev\/sda1) under \/mnt\/sysimage\/boot..\u00a0\u00a0\u00a0 I had decided to use btrfs for the ‘new’ root partition, but – being over-cautious – kept the boot partition as ext4..<\/p>\n After running the (modified<\/em>) commands mentioned in the article – and remembering to update \/etc\/fstab<\/strong> – the system booted correctly..<\/p>\n This is – of course – rather Fedora-specific, but it is possible to get dracut<\/strong> on other Distros..<\/p>\n Robert Gadsdon.\u00a0\u00a0 June 2, 2016.<\/em><\/p>\n <\/p>\n","protected":false},"excerpt":{"rendered":" My ‘system disk’ (\/dev\/sda) started to show bad sectors, recently, and so I decided to replace it.\u00a0\u00a0\u00a0 The disk was around 8 years old, and had been in almost-continuous use..
