Hi, I deleted a zfs snapshot because it was as big as the original zfs. After the snapshot was removed, all the data in the original zfs is gone. How this happened? Can I restore the snapshot? Please help. Thanks a lot! (5 Replies)
I created a zpool and in it there is a zfs volume. I used that to backup data on another server using ISCSI. Now I have the data and want to take a snapshot so that I can view it on another machine that is not in production.

mksnap_ffs
MKSNAP_FFS(8) BSD System Manager's Manual MKSNAP_FFS(8)NAME
mksnap_ffs -- take a file system snapshot
SYNOPSIS
mksnap_ffs snapshot_name
DESCRIPTION
The mksnap_ffs utility creates a snapshot named snapshot_name.
The group ownership of the file is set to ``operator''; the owner of the file remains ``root''. The mode of the snapshot is set to be read-
able by the owner or members of the ``operator'' group.
EXAMPLES
Create a snapshot of /usr/home file system and mount the snapshot elsewhere:
mksnap_ffs /usr/home/snapshot
mdconfig -a -t vnode -o readonly -f /usr/home/snapshot
mount -o ro /dev/md0 /mnt/
SEE ALSO chmod(2), chown(8), mdconfig(8), mount(8)HISTORY
The mksnap_ffs utility first appeared in FreeBSD 5.0.
CAVEATS
The disk full situation is not handled gracefully and may lead to a system panic when no free blocks are found.
Every filesystem can have only up to 20 active snapshots. When this limit is reached, attempting to create more snapshots fails with ENOSPC,
and mksnap_ffs reports that it is ``out of space''.
