Re: FW: Mount JFFS2 root file system issue

Hello All,
I have ARM9 systems with JFFS2 root file system. For some reasons, e.g.
system crash or power failure, when system boots up next time, it takes
much longer time than usual to mount jffs2 root file system. It can hang
at following message for 3-10 min. The system will eventually come up
and function well. This problem occurred on less than 10% of boards.
I think this can happen (after such a failure) when JFFS2
realizes that it needs to rebuild/recover the active
nodes in the file system. This can require a scan of
the entire file system, along with rewriting some nodes, etc.

There are some symbolic links in the root file system. These links is
linked to the files in another partition. Could that cause problem if
the file in the other partition gets corrupted? This behaviour is not
reproducible. Looks like the files in the flash are not corrupted. I
guess the corruption could be in jffs2 file system.
Anyone has seen this issue, and solution?
Appreciate very much for any input,
This looks to be a Linux kernel issue - I don't see what it
has to do with eCos.
You should probably ask on some appropriate Linux mailing list.
