Maybe the crypto setup failed and /dev/mapper/enc-a has not been decrypted. What does


$ dd if=/dev/mapper/enc-a bs=1k count=20 | less

or

$ dd if=/dev/mapper/enc-a bs=1k count=20 | file -

show you? Here I can "less" through something which appears to an XFS header, ater this I can even see filecontents. The 2nd command should show sth. like "SGI XFS filesystem data".

And don't forget to use a current kernel/xfsprogs before doing sth. with the FS....


Hello,

Thank you for the reply. You are probably right. After the third reboot the 3 filesystems seem to be working as usual (which is fine) and nothing appears to be corrupted in any way. I'm not really sure about what happened but, it could be the encryption.

Thank you,

Best Regards
