/boot why 250 MB

[frank19991999]

Just wondering what are the reasons to increase the boot to 250 MB.

Thx

is this default oprtion with ESX 3.5 or something? i.e. automatic partitioning? 100MB should work just fine..... the COS kernel is bumped up to 2.4.21-47.0.1.ELvmnix but that hardly requires 250MB /boot partition.

The reason I teach for using /boot as 250MB is that on ESX 2.x the default /boot size was 50MB, when an ESX server with this size /boot partition was upgraded to ESX 3.x the upgrade failed with a lack of disk space in /boot.

There is a tech note about cleaning up /boot to allow an upgrade with a 50MB partition, but I teach a 350MB /boot as having the best chance of being compatible with a 4.x upgrade.

I also teach that /boot should be kept small to minimise the chance of corruption as it contains the file ssytem cleaning tools.

I do this for the exact same reason as ac57846 mentions.

Boot partition tores information required to boot the ESX Server host system. For example, this is where the grub and LILO boot loaders reside. The boot drive usually defaults to the specified /boot partition location.

Here are the details of ESX partitions from old to new partition standards. You can increase to 250MB for /boot and 4096MB for other partitions if you want since servers ship with tons of hard drive and would be good to have more space for /tmp /var /home etc...its your choice to increase. Read for more details.

Hello,

Most modern multi-disk Linux distributions have a /boot size of at least 190MBs. Increasing it does give you more room for kernel upgrades and the like.
