I only want the raid to work just one time, cause there is data I want to (but not in any case) be secured. Then I again install ext3 on it... this worked on this raid without any problems at all. And the fsck is about 2 houres, not 28 hours (--rebuild-tree).
no, the hdd is a software raid 5, /dev/md0, which is piped through aes
via cryptsetup, so it is accessed via /dev/mapper/hdb
My experience with such a stacking and reiserfs was horrible. Continous
filesystem corruption that finally required reformatting. I then
replaced reiserfs with ext3 and the stacking works since then.
It is not a dm-crypt problem as the symptoms also occurred with
raid5/lvm2/reiserfs, so any raidx/dm/reiserfs stacking seems to be only
something for the more adventurous folks. Thus I don't know if the
problem still exists with current kernels.
