Strange mounts listed in 9.3

[mgh333]

These may have existed in 9.2.1.9, but the upgrade fubar'd so I had to install on new flash and import volumes, then upload config. After that I ended up upgrading the firmware on my LSI 9211-8i to P16. Everything looks stable now and all is working, but I noticed some strange mounts.

These top ones look normal:

freenas-boot/ROOT/default on / (zfs, local, noatime, nfsv4acls)
devfs on /dev (devfs, local, multilabel)
tmpfs on /etc (tmpfs, local)
tmpfs on /mnt (tmpfs, local)
tmpfs on /var (tmpfs, local)
freenas-boot/grub on /boot/grub (zfs, local, noatime, nfsv4acls)
ZFSV01 on /mnt/ZFSV01 (zfs, local, nfsv4acls)
ZFSV01/media on /mnt/ZFSV01/media (zfs, local, nfsv4acls)
ZFSV01/music on /mnt/ZFSV01/music (zfs, local, nfsv4acls)
ZFSV01/vault on /mnt/ZFSV01/vault (zfs, local, nfsv4acls)
ZFSV02 on /mnt/ZFSV02 (zfs, local, nfsv4acls)
ZFSV02/DataBackup on /mnt/ZFSV02/DataBackup (zfs, local, nfsv4acls)
ZFSV02/SYSTEM on /mnt/ZFSV02/SYSTEM (zfs, local, nfsv4acls)

These do not look right, no idea where they came from.

ZFSV01/.system on /var/db/system (zfs, local, nfsv4acls)
ZFSV01/.system/cores on /var/db/system/cores (zfs, local, nfsv4acls)
ZFSV01/.system/samba4 on /var/db/system/samba4 (zfs, local, nfsv4acls)
ZFSV01/.system/syslog-b00a140f145d479d9b9a0b89cd24fbd2 on /var/db/system/syslog-b00a140f145d479d9b9a0b89cd24fbd2 (zfs, local, nfsv4acls)
ZFSV01/.system/rrd-b00a140f145d479d9b9a0b89cd24fbd2 on /var/db/system/rrd-b00a140f145d479d9b9a0b89cd24fbd2 (zfs, local, nfsv4acls)
ZFSV01/.system/configs-b00a140f145d479d9b9a0b89cd24fbd2 on /var/db/system/configs-b00a140f145d479d9b9a0b89cd24fbd2 (zfs, local, nfsv4acls)

Just checking, is it safe just to umount these and be done with it? ZFS01/.system does not exist btw.

Thanks,
Mike
