Writing to this filesystem, from another similarly encripted filesystem, large files (between 300 and 400 MB), locks the console where the copy is having place. The copy process stops. It is unkillable. Umount of that filesystem locks (and umount is unkillable). Reboot filesystem locks.
Interestingly enough I've experienced a similar problem with dm-crypt at home. Using cryptoloop works for me. Please open a bug report for the kernel. Maybe it's a generic problem outside of cryptoloop/dm-crypt.
This problem continues. Soon after I write large files to an encrypted, loop mounted, filesystem, the operation locks. All programs are thereafter unable to exit or be killed -9, and system can not even reboot or halt, only power switch works, forcing a huge fsck. It does not matter if filesystem is mounted through device mapper, new style (dm-crypt), or old style (cryptoloop). Tonight I tried new style. /etc/crypttab: mycrypt_mm_f /biggy/crypta_f.mm.x none cipher=twofish-cbc-plain,size=256,hash=sha512,noauto,loop /etc/fstab: /dev/mapper/mycrypt_mm_f /mnt/crypta.mm.x xfs noauto,user,noatime,nodiratime 1 4 nimrodel:~ # df -h /mnt/crypta.mm.x Filesystem Size Used Avail Use% Mounted on /dev/mapper/mycrypt_mm_f 28G 19G 9.3G 67% /mnt/crypta.mm.x Mounted as: /dev/mapper/mycrypt_mm_f on /mnt/crypta.mm.x type xfs (rw,noexec,nosuid,nodev,noatime,nodiratime) Logs: nothing is logged anywhere. Nothing! Reported as Bug #345039, but there has been no comments at all. :-?? I'd be happy to try kernel options to enable more logging, or try tests... I can trigger the bug at will, it is reproducible here. - -- Cheers, Carlos E.
