Note: "permalinks" may not be as permanent as we would like,
direct links of old sources may well be a few messages off.


I have been using DRBD for 5 months on an FTP server. I had do a full
resynch over a 10 Mbit link, so I decided to drop the partition ( was 18
GB used on 120GB ) reformatted the partition and DRBD device is back in

Now when I am browsing the partition, it freezes once in a while ( and
this is obviously on the master machine, since the partition is not
mounted on the secondary )

Like when I do a simple ls, I will freeze for 5-6 seconds.

What is funny is that I never did this before I reformatted the
