Having option to fsck while filesystem is online takes that annoyance away. So yes, it would be very useful for me... For long-running servers, this may be less of a problem... but OTOH their filesystems are not checked at all as long servers are online... so online fsck is actually important there, too, but for other reasons. So yes, it is very useful for world. Pavel -- (english) http://www.livejournal.com/~pavelmachek (cesky, pictures) http://atrey.karlin.mff.cuni.cz/~pavel/picture/horses/blog.html
