Hey Rick,
thx for the quick reply. Alright, I am gonna try a newer kernel next
then. I am running the default up2date Lucid kernel right now which is
2.6.32-24-server.
Take care
Thorsten

Had those self-same issues (well, crypted RAID-array io-locking on me during samba-operations on it), and moving to kernel 2.6.34 fixed it for me.
Never figured out what was really causing those problems.

Hey folks,
I am switching from loop-aes to dm_crypt. I am trying to use it on a
fresh Ubuntu 64bit server installation with my 6x750gb Software raid5
array.
Array is clean and freshly created, I encrypted it using
cryptsetup -y -c aes -h ripemd160 -s 256 create STUFF /dev/md0
Format went fine, but when I try to copy back large amount of data to
the encrypted array (about 900gig) my copy thread always hangs itself at
some point during the process. I can't access the array anymore, though
the raid itself is fine, no drives are kicked out or anything.
Reboot gives me back access and the array is still ok.
When the problem occures I see the following trace in log:

Using the array uncrypted, data copy to it works just fine, copied over
the full 900 GB now 6 times without a hickup.
Can anybody help me with this?
thanks
