Disk space is cheap, but fscking a large volume takes forever.
It would be good if online/background fsck was available, like it is for
We have some ideas around improving fsck performance with a combination of
readahead and lazy initialisation of on-disk data structures. But background
fsck is not on the roadmap and is not currently under consideration by the ext3
maintainers; and given the complexity of an implementation, this is unlikely to
change in the short term.
Thanks for the helpful reply.
Would you also consider a more intelligent (non-restarting) fsck too? (bug 178468)
