Nein, man sollte sich nicht wundern, dass das System sich so träge anfühlt, wenn /proc/mdstat folgendes zeigt:

md0 : active raid5 sdb[0] sdd[2] sdc[1]
      67108608 blocks level 5, 128k chunk, algorithm 2 [3/3] [UUU]
      [==========>..........]  resync = 53.2% (17870972/33554304) finish=7.3min speed=35319K/sec

It happened again. The linux-2.6 2.6.20-1 release failed for arches which we don't build snapshots for. This means that none of them was ever built in the time after I commited the whole stuff.

As this happens over and over again I consider this a real problem now. So the following arches needs new debian-kernel maintainers: alpha, hppa, and mips.

I thought the problems with pvmove was fixed with devmapper 1.02.12, but I just run into this problem again. Not sure if there was different fixes in later versions.

pvmove suspends the devices and fails to reload tables under some conditions. This time it just blocked while the devices for /usr und /var was suspended. This means the system is dead.

Update: It seems to be related to the number of LVs to move. Only one works all the time.
