Oracle Exam 1Z0-820 Topic 4 Question 104 Discussion

Actual exam question for Oracle's 1Z0-820 exam

Question #: 104
Topic #: 4

You need to migrate a UFS file system named /production_ufs to a ZFS file system named /production_ufs. The /production_ufs file system cannot be taken down or be out of production during the migration, and the current /production_ufs file system must remain active until the /ptoduction_zfs file system is copied and ready.

Which method allows you to meet both requirements?

1. Copy live data from /production_ufs to /production_zfs while /production_ufs is in use.

2. When the copy is complete, /production_zfs will contain an up-to date copy of /production_ufs

ACreate a snapshot of the UFS file system.
Create the new ZFS file system.
Use cpio to copy data from the snapshot to the new ZFS file system.

BCreate a new Boot Environment.
Create the ZFS file system.
Use lucreate -m to copy data from the Current UFS file system to the new ZFS file system.

CMirror the existing UFS file system by using SVM.
After both submissions are in sync, migrate one of the submissions to a ZFS file System by using Live Upgrade.

DCreate the new ZFS file system by using zfs create import to import data from the existing UFS file system into the new ZFS file system

ECreate the new zfs file system by using the zfs create -o shadow.

Whoa, 'zfs create -o shadow'? That's a new one to me. Sounds like a bit of a wild card, but hey, you never know, it might just work! I'd want to do some serious research on that option before considering it.

Oh, the good old 'zfs create import' trick, huh? I like the simplicity of that option, but I'm not sure if it's the best way to handle the requirement of keeping the production system active during the migration.

C) Mirror the existing UFS file system by using SVM. After both submissions are in sync, migrate one of the submissions to a ZFS file System by using Live Upgrade.

Option C with the mirror and Live Upgrade approach is an interesting choice, but it seems a bit more complex than the other options. I'd want to make sure I fully understand the process before going with that one.

I'm leaning towards Option B. Using lucreate to copy the data from the Current UFS file system to the new ZFS file system sounds like a good way to minimize downtime and keep the production system active.

Option A seems like the way to go. Creating a snapshot of the UFS file system and then copying the data to the new ZFS file system allows me to keep the production system running while migrating the data. It's a clean and efficient approach.
