Hi,
JFTR: I was experimenting with such stuff, too, today and couldn't
reproduce this issue with these commands on Squeeze amd64:
502 lvcreate -L 128M -n foobar vg0
503 mkfs.ext4 /dev/vg0/foobar
504 mount /dev/vg0/foobar /mnt/tmp/
505 cd /mnt/tmp/
506 ls -l
507 echo foo > bar
508 cd
509 umount /mnt/tmp/
510 lvcreate -L 64M -n foobar-snapshot -s /dev/vg0/foobar
511 lvs
512 mount /dev/vg0/foobar /mnt/tmp/
513 lvs
514 cd /mnt/tmp/
516 lvs
517 ls -l
518 echo fnord > bar
519 echo foobar > bla
520 lvs
521 cd -
522 umount /mnt/tmp/
523 mount /dev/vg0/foobar-snapshot /mnt/tmp/
524 ls -l /mnt/tmp/
525 umount /mnt/tmp/
527 lvs
528 lvresize -L 32M /dev/vg0/foobar-snapshot
529 lvs
530 fsck /dev/vg0/foobar-snapshot
531 fsck -f -C0 /dev/vg0/foobar-snapshot
532 lvs
533 mount /dev/vg0/foobar-snapshot /mnt/tmp/
535 ls -l /mnt/tmp/
536 umount /mnt/tmp/
537 lvs
539 lvrename vg0 foobar blafasel
540 lvs
541 lvrename vg0 foobar-snapshot blafasel-snapshot
542 lvs
543 lvrename vg0 blafasel foo
The only things in the dmesg output:
Aug 10 17:07:40 acromantula kernel: [2940774.130094] EXT4-fs (dm-15): mounted
filesystem with ordered data mode. Opts: (null)

Aug 10 17:14:44 acromantula kernel: [2941198.047796] EXT4-fs (dm-16): mounted

Looks fine for me.
Regards, Axel
