Are there any instances where 2efsck will run automatically?=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.

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.

=20

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)?

=20

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

Mar 14 08:21:01 g6r10 kernel: EXT3-fs warning: maximal mount count =
reached, running e2fsck is recommended

Mar 14 08:21:01 g6r10 kernel: EXT3 FS on sda1, internal journal

Mar 14 08:21:01 g6r10 kernel: EXT3-fs: mounted filesystem with ordered =
data mode.

Thank you,
