Hello, |

I see this msg in /var/log/dmesg: |
4 |
|
5 |
[ 4.444826] EXT2-fs (sdb3): error: couldn't mount because of |
6 |
unsupported optional features (2c0) |
7 |
[ 4.468074] EXT4-fs (sdb3): mounted filesystem with ordered data |
8 |
mode. Opts: (null) |
9 |
|
10 |
but my system boots. Is the (2c0) the clue to what features are meant? |

Next question: |

From this article: |

I get a good description of *journal*, *ordered* and *writeback* |
19 |
journaling levels and I wonder if my root filesystem should have |
20 |
*ordered* mode. I recently had a total crash of my ext3/4 root and |
21 |
home filesystems, where the directories were lost and I had to paste |
22 |
everything back together again by guess and by golly. In decades of |
23 |
linux usage, that's never happened to me on that scale. I'd hoped for |
24 |
more from journaling filesystems. |
25 |
|
26 |
Did it happen only because gentoo gave me *ordered* data mode by |
27 |
default and I should have had *journal*? |
