I moved away from reisefs to ext4 because I was getting some random lockups |
11 |
when I/O was high. While on reiserfs I also had a couple of corrupt mysql |
12 |
files and all around poor performance. Now, this was on a machine with a |
13 |
deficient PSU (I replaced a couple of capacitors since then and it is now |
14 |
working properly) so I don't want to blame the filesystem because of this |
15 |
hardware problem. In any case, under these impaired conditions ext4 was a |
16 |
much better performing filesystem than reiserfs. No lock ups, significantly |
17 |
faster and no corruption was observed in normal operation - I didn't try to |
18 |
hammer it. |

So I read your paragraph above with surprise, because in my experience the |
21 |
opposite was true. At the time I thought that reiserfs was perhaps suffering |
22 |
from bitrot, because these symptoms had gotten worse over time. This is on an |
23 |
installation running since 2005. Not sure what to conclude from these |
24 |
anecdotal observations ... :-/ |
