Finding ZFS .zfs/snapshots directory in OpenSolaris

  • 772

My home directory in OpenSolaris 0906 is part of the zpool rpool. I can view the pool in zpool list. I can view the file system in zfs list. I can create snapshots. I can use zfs list and see a list of the snapshots I've taken. It's my understanding there should be a .zfs directory inside /export/home/test at /export/home/test/.zfs

zfs snapshot rpool/export/home/test@1

creates my snapshot successfully 

zfs list -t snapshot

shows my snapshots successfully

I can't figure out where to find the snapshots. I see no .zfs directory anywhere.

Any hints where else I should look or what else I should do to find the .zfs directory and the snapshots?

    Change the snapdir property of the dataset if you need to make it visible.

    # ls -la /rpool/
total 6
drwxr-xr-x  5 root root  4 2010-09-14 05:21 .
drwxr-xr-x 25 root root 25 2010-11-18 13:18 ..
dr-xr-xr-x  4 root root  4 2010-09-14 05:15 .zfs
drwxr-xr-x  3 root root  3 2010-09-14 05:15 boot
drwxr-xr-x  2 root root  3 2010-09-14 05:21 etc

# zfs set snapdir=hidden rpool

# ls -la /rpool/
total 6
drwxr-xr-x  4 root root  4 2010-09-14 05:21 .
drwxr-xr-x 24 root root 25 2010-11-18 13:18 ..
drwxr-xr-x  3 root root  3 2010-09-14 05:15 boot
drwxr-xr-x  2 root root  3 2010-09-14 05:21 etc

  2. The snapshot directory should be in /export/home/test/.zfs.

    This directory doesn't appear with a simple "ls -a", you need to specify it explicitly.
