Hi experts,
Short question
What happen if we have cross zpool mount ?
meaning :
zpool A -> should be mounted in /A
zpool B -> should be mounted in /A/B
=> is there in zfs an automatic mechanism during solaris 10 boot that
prevent the import of pool B ( mounted /A/B ) before trying to import A
pool or do we have to legacy mount and file /etc/vfstab
Regards,
Laurent

Where /A is from the root pool, you should be safe most of the time. If not, set the canmount promptery of the "Pool B /A/B" dataset to noauto, otherwise it may bet mounted without /A being mounted, which depending on your situation can be a minor irritation or a serious problem. -- Any sufficiently advanced technology is indistinguishable from magic.
