The idea is to have /boot (with ext, since grub2 does not support f2fs yet) and / with f2fs. Both on the USB flash drive while /home will be somewhere else. Now, I've a backup tool exploiting lvm snapshots and I would like to use it. This means / will be on top of an LV. Does it make any sense to have f2fs over lvm? Will still be some benefits from f2fs in this setup? How about snapshots? Could they cause problems? Usually the filesystem mounted from lvm snapshot has consistency issues, which are they usually solved by journal. I guess f2fs should be fine, but I would like to confirm with experts here. Of course, one possibility would be to use f2fs on the raw partition, waiting for snapshot to be implemented. What's the plan about this? Thanks a lot for any answers, bye, -- piergiorgio ------------------------------------------------------------------------------ Check out the vibrant tech community on one of the world's most engaging tech sites, Slashdot.org! http://sdm.link/slashdot
