I have the following file system, that needs to be expanded to more 500Gb, so a total of 1Tb:
I am not familiar with zfs, I am more used to ufs, so how can I go about it?
thanks for the reply.
The previous sys admin setup this server like this below:
Now, the oracle dba wants me to either expand /oradata1or create a new /oradata2
Sorry to butt in, but as an aside to your main question, I'd be far more worried about this before thinking about doing anything else:
The oradata pool is in a degraded state, which means it's experienced a failure of some kind and so its redundancy is likely to be severely reduced or non-existent. As a priority, you probably want to run zpool status -v oradata and see what has actually gone wrong and sort that out.
Of course, if the oradata pool isn't in use any longer or you otherwise have reasons not to care about its data then that's fine I suppose. But I just thought I'd mention this, since if it were me, and this is a live pool, I'd want to sort this out urgently before doing anything else.
OK. Well, if you're 100% absolutely sure you don't care about anything that happens to the data on that pool, then I suppose there's nothing you need to do about it.
Returning to your original question: firstly, I have to say I'm relatively new to ZFS myself, having only recently come back to Solaris on a regular basis. But from what I've learned thus far, the first thing is (as per the earlier advice from DukeNuke2) to figure out what kind of pool you've got. The Oracle documentation he linked you to this morning is also excellent, and covers pretty much everything you need to know in terms of how to add things.
So take a look at the output of zpool status -v oradata1, find out if it's made of mirrors, some kind of RAID, what devices are in it, and then once you know that you'll be able to determine the best way to add a device to it.
Your root pool is almost full, has only 4% left:
You are strongly advised to leave more free space in active ZFS pools as otherwise, the performance will suffer a lot due to the system trying to find free space and the data fragmentation resulting from the lack of contiguous areas. Not exceeding 80% is a safe bet.
Back to the topic, the "long" name reported for the oradata disk (c4t500A09828DE3E799d0) suggests a storage array is used to build this pool.
Exanding the oradata1 pool might then be achieved simply by enlarging the underlying LUN. Depending on your ZFS settings, nothing more might be required.
You might want to post these commands output for us to get a better idea about your configuration:

Hi All,
I have Solaris-10 configured with two non-global zones. All file-systems are mounted on global zone and data file-systems are mounted on non-global zone as lofs.
I have added 4 luns of 100 GB each and still not able to extend a file-system. This is production server, so I can not... (5 Replies)
Hi, I need to expand a ZFS volume from 500GB to 800GB. I'd like to ask your help to confirm the following procedure:
Can I do it on the fly without bothering the users working on this volume?
Thank you in advance! (6 Replies)

I have Solaris-10 (Update-7). This is having ZFS file-system and 10 sparse-root zones are there.

I am working on a server where the 'root' user ZFS filesystem.
Now when I do Top commands it says only 750M free .But when I count the actual memory utilized it comes only to 12 GB and the total size of the server is 32G.
I think rest of the space is held up by ZFS file system.
Is there a... (5 Replies)
