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

Don't stop worrying!
An hour after we started drbd sync to the secondary, we got this:

Oct 12 13:13:16 snfs1 kernel: EXT3-fs error (device drbd0):
ext3_readdir: bad entry in directory #89899527: inode out of bounds -
