For reference, a comparison. Here with ZEVO Community Edition 1.1.1 on OS X 10.8.2 (and
experimental automated snapshots) with a ZFS slice on the disk that's internal to a MacBookPro5,2 I unmounted a child file system before I went to bed –
gjp22/intrigue
After I woke, as expected:
- Code: Select all
macbookpro08-centrim:~ gjp22$ diskutil list | grep zfs
0: zfs_pool_proxy gjp22 *614.2 GB disk3
1: zfs_filesystem_proxy intrigue 188.9 GB disk3s1
0: zfs_pool_proxy zhandy *635.7 GB disk6
1: zfs_filesystem_proxy Pocket Time Machine 129.3 GB disk6s1
macbookpro08-centrim:~ gjp22$ mount | grep zfs
/dev/disk3 on /Volumes/gjp22 (zfs, local, journaled, noatime)
/dev/disk6 on /Volumes/zhandy (zfs, local, journaled, noatime)
/dev/disk6s1 on /Volumes/zhandy/Pocket Time Machine (zfs, local, journaled, noatime)
Then, some messing around (experimenting with a
partition type instead of
file system type):
- Code: Select all
macbookpro08-centrim:~ gjp22$ mount -t zfs_filesystem_proxy /dev/disk3s1 /Volumes/gjp22/intrigue
mount: exec /System/Library/Filesystems/zfs_filesystem_proxy.fs/Contents/Resources/mount_zfs_filesystem_proxy for /Volumes/gjp22/intrigue: No such file or directory
Then a fluffy (not proper) check for mount point conflict:
- Code: Select all
macbookpro08-centrim:~ gjp22$ ls -d /Volumes/gjp22/intrigue
/Volumes/gjp22/intrigue
macbookpro08-centrim:~ gjp22$ ls -ld /Volumes/gjp22/intrigue
drwxr-xr-x 2 gjp22 wheel 2 6 Nov 04:15 /Volumes/gjp22/intrigue
macbookpro08-centrim:~ gjp22$ ls -l /Volumes/gjp22/intrigue
Then again messing around:
- Code: Select all
macbookpro08-centrim:~ gjp22$ mount /dev/disk3s1 /Volumes/gjp22/intrigue
mount: You must specify a filesystem type with -t.
And finally:
- Code: Select all
macbookpro08-centrim:~ gjp22$ mount -t zfs /dev/disk3s1 /Volumes/gjp22/intrigue
macbookpro08-centrim:~ gjp22$ mount | grep zfs
/dev/disk3 on /Volumes/gjp22 (zfs, local, journaled, noatime)
/dev/disk6 on /Volumes/zhandy (zfs, local, journaled, noatime)
/dev/disk6s1 on /Volumes/zhandy/Pocket Time Machine (zfs, local, journaled, native)macbookpro08-centrim:~ gjp22$ ls -al /Volumes/gjp22/intrigue
total 112
drwxr-xr-x 2 gjp22 wheel 2 6 Nov 04:15 .
drwx-wxr-x 193 gjp22 wheel 318 12 Nov 23:18 ..
– neither an error at the command line, nor a mount.
Whilst it's not explicit in Apple's manual pages, I have a vague notion/recollection that (from the OS X perspective, not necessarily ZEVO/ZFS) for some things: the mount
verb of the diskutil command is preferable to the mount
command …
