I rebooted my server tonight and was greeted with this message while watching the boot process via IPMI:
blk_update_request: critical medium error, dev sdi, sector 17774192
“smartctl -a /dev/sdi -d scsi” yields:
smartctl 7.0 2018-12-30 r4883 [x86_64-linux-4.12.4-1.el7.elrepo.x86_64] (local build)

So, two questions:
- Is there any reason I couldn’t just make an image of my system disk (64 GB, USB 3.0 flash drive), restore it to another drive, and boot from the new drive without any further configuration?
- Is there a “best” flash drive to use? I can find really expensive stuff, but I’m not convinced it is significantly better than the $12 Samsung flash drive.
