boot device options
Looking for some feedback and some direction on not only the feasibility
but does it makes sense to do.
The scenario is this, this is Fedora 26 system, running RAID1 on all
disk partitions, there are only 2 disks in the system with 4 raid
partitions each:
/dev/md125 / - md125 : active raid1 sdb1[2] sda1[0]
/dev/md127 /boot - md127 : active raid1 sdb3[1] sda3[0]
/dev/md124 /home - md124 : active raid1 sdb5[1] sda5[0]
/dev/md126 [swap] - md126 : active raid1 sdb2[3] sda2[2]
The thought is to use flash of some sort to do the initial boot (eg USB
flash) and then continue with the boot using the installed disks. If
this is the case is it the /boot partition that gets moved to flash? is
it grub that gets moved? Or is it both? /boot is currently using about
174MB.
The thought behind this to protect against a disk failure and being
unable to boot on the remaining good disk, flash being solid state I
would assume it would be more reliable, plus since I'm not looking to
constantly write to the partition "wearing out" the media wouldn't be an
issue.
USB device I was thinking about is Z-U130 eUSB SSD, they appear to be
available as 1, 2, 4, & 8 GB modules.
Thanks, Jeff
