Hi, I was just reading about filesystems and my ideas are a bit confused. I read quite a few articles on net but still my basic doubts are not completely clarified. I thought this would be the right place to ask, since many journalling gurus might be here. Can someone tell me do journalling fs maintain journal about the metadata or the all the data? Also, is it true that now-a-days there is no such thing as inode "block" since for faster access the inodes are kept near the data itself? How is the journal maintained? How is it prevented from being too big and why are these fs not slower than traditional fs since it involves an overhead of writing to a journal? And lastly don't the journalling fs give a false sense of security to the user, saying that the data is written to disk when in reality only an entry is made in journal and data is still not committed to disk.
Thanks a lot for the patience and eagerly waiting for any replies. With warm regards, -Payal
