15 But it does not help :( After unmounting /32/dev, I can finally unmount
16 /32, but now the fsck fails:
17
18 weird ~ # fsck -Cf /dev/mapper/32
19 fsck from util-linux 2.19
20 e2fsck 1.41.14 (22-Dec-2010)
21 fsck.ext3: Device or resource busy while trying to open /dev/mapper/32
22 Filesystem mounted or opened exclusively by another program?
23
24 lsof and fuser report nothing. I guess I will have to reboot then.
