I would think it will run automatically any time there's an unexpected
SSC reboot -- either a Linux kernel oops or a power failure.

Are there any instances where 2efsck will run automatically?=20
=20
Want to know if we think we are going to see the same type of failures
in the field that we see today when on the bobcat flash fsck blows away
files.

Thanks,

We should fix this before Cougar ships, maybe with the tune2fs command
Raj linked.  We have lots of Linux-savvy customers and they will see
this when they poke around, and open support cases on it.  ("How do I
run e2fsck on the flash?"  "Why aren't you fscking your flash
regularly?"  Etc.)

John,=20

   This is just the behavior of the ext3 file system used in Linux.
After a certain number of reboots this message appears. It is ok to
ignore this message.

Andy might have more to say about it.

I notice the following 4 lines when I mount the secondary flash's root
partition. Are these normal and expected (the second one seems the most
concerning)?

Mar 14 08:21:01 g6r10 kernel: kjournald starting.  Commit interval 5
seconds

Thank you,
