I have smartd running. A short self test is done every day, and a long test |
| 16 |
once per week. |

Didn't you get errors in yslog then? |

I also thought about swapping the system drive - I have a larger backup |
| 25 |
drive, with nearly identical logical volumes on it, where I make backups |
| 26 |
with rdiffbackup. So even the content is identical, except for an additional |
| 27 |
rdiff-backup directory containing the increments. So all I have to do is to |
| 28 |
echange the two volume group names, reboot, and the system will run from the |
| 29 |
other drive. But I very much doubt this will help, transfer speed looks okay |
| 30 |
to me, around 100 MB/s with dd. |
