Comment 5 for bug 1297012

Hi Dimitri,

Thanks for the explanation. The reason we are having trouble with ext2 is because ext2 does not seem to have a freeze file-system interface. The freeze interface typically flushes all dirty buffers to disk and allows the creation of a file-system consistent snapshot prior to backup. If we take a non file-system consistent backup then restoring the volume later would cause fsck checks that may alarm users or corrupt the file-system in unknown ways.

We can recommend customers to use ext4 in our documentation however it is often that people just go with the default choice. This is the reason why we were wondering if you could change the boot file-system to ext4.

If you do not expect /boot to be modified then wouldn't the journal have a very low impact anyway? Could we tune the journal to be of a small size?

Let me know your thoughts.
Thanks,
Abhishek
