If there's a message telling you "unknown option luks", I would consider it as a bug in the boot.crypto system unless proved otherwise and opened a bug report for it. Is there a possibility to upgrade? > /var/log/messages: > Jan 7 17:19:51 linux-wh8s kernel: XFS: bad magic number > Jan 7 17:19:51 linux-wh8s kernel: XFS: SB validate failed This indicates a major problem with the XFS superblock.

[....] These are illegal XFS mount options and can be the cause that the underlying filesystem doesn't get mounted. As a starting point, Please read here: http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=blob;f=Documentation/filesystems/xfs.txt;hb=HEAD > Now, the xfs-partition was opened and there was error message promptwise or in > the /var/log/messages: So I can consider your problem solved? That's fine! > Could I also have specified better the mkfs.xfs commandline too? > I just have done: mkfs.xfs /dev/hd.. That's a matter of opinion and circumstances. Here's what I'm using, regardless of encryption: mkfs.xfs -f -l lazy-count=1,version=2 -i attr=2 -d agcount=6 /dev/xxx In fstab, I mount with rw,noatime,logbsize=256k,logbufs=2,nobarrier Please keep in mind that the "nobarrier" option gives great speed and latency, but could cause severe data loss in case of a crash or power failure. My systems are backuped by an UPS. (And I can remember having read "barriers not supported" in your logs, this means the same). _______________________________________________ dm-crypt mailing list dm-crypt@xxxxxxxx http://www.saout.de/mailman/listinfo/dm-crypt
