Dear JFS group,
I have a question on the implementation of JFS as root file system on Linux. Consider
the case JFS is used
as root file system and is not unmounted cleanly.
JFS does replay its log in an user program, not in the kernel. How does it apply the
log before mounting a JFS root file system?
It seems to me that JFS will mount a potentially
inconsistent / JFS read-only first and then only later do the log replay in the file
system checker with logredo. Is that correct? Doesn't that cause problems
with the kernel image of the fs getting inconsistent
with the result of the log replay?
Thank you for any insights.
