zfs similar folder names erased at once

[nokeabue]

moving files from pool1 to pool0 found something strange regarding ZFS deleting similar folders.
see.

--------------
root$ cd /mnt/pool1

pool1$ls .
. .. CAPS caps

pool1$ mv -v CAPS /mnt/pool0

pool1$ cd /mnt/pool0

pool0$ls .
. .. CAPS caps

pool0$ rm -rf caps

pool0$ ls .
. ..
---------------


it means both folders were deleted.

why could be that happening?

I was unable to reproduce this. BSD is case sensitive, so this shouldn't happen. You'd see more details of the files using ls -la. Maybe there's more going on in the directory than you can see. Here's what I tried:

Code:

root@nas2 temp # ls -la

drwxr-xr-x  3 root  1002  3 Apr 21 20:30 .

i´ll replicate the error.

i find it a couple of times now i see while moving data along pools from client-side.

* zfs get all TANK0/server telling me the dataset is case-sensitive which should be ok
* checkout if CIFS or NFS related
* no dedup or compression so far.
