And I've spent all-nighters restoring from ext2 filesystems, simply because |
| 7 |
the system wasn't shut down properly. |

I just had strange undeletable files on my ext2 filesystem less than a |
| 16 |
week ago. In fact, once I finally got it fixed, it happened two more times |
| 17 |
that same night. |

You also suggested ext3. Ext3 has been a disaster for me thus far. It's |
| 20 |
been the only filesystem I've had trouble with (outside of the typical |
| 21 |
issues we're all used to with ext2). However, I wouldn't go so far as to |
| 22 |
say nobody should use it just because I and a few people I know have had |
| 23 |
bad experiences with it. I know there are people out there running it |
| 24 |
successfully but I wouldn't even trust it to hold my /tmp filesystem. |

I just can't agree. What exactly is your required time frame for running |
| 34 |
reiserfs with no problems before you think it's stable? I personally have |
| 35 |
been running reiserfs on my systems since before it was even merged into the |
| 36 |
mainline kernel. I work the hell out of my systems and I've never had a |
| 37 |
problem. |
| 38 |
|
| 39 |
I've had it in production systems as well, for almost as long. In systems |
| 40 |
ranging from large, high load email servers, to web servers handling approx |
| 41 |
1.5 million page views a month. I've never had a problem with it. |

I'm not trying to be insulting, but lets not forget the human factor in this |
| 44 |
equation. I don't really know you, or the people you cite, so please don't |
| 45 |
take this as a slam on your skills, I'm just noting there's more to factor |
| 46 |
in here than just the filesystem. If you don't know reiserfs that well, and |
| 47 |
just know ext2, or ext3 maybe you have less problems because of that, rather |
| 48 |
than because of the relative quality of the two filesystems. |
