how to extend a file system in Celerra
Hi
Does any one know how to extend a File system in Celerra, let me tell you.
I have a file system in celerra and it reached its treshold capacity 90%, this file system is share to a Solaris Server by using NFS I have 3 questions.
1. to extend the File system in Celerra do i need to unmount the file system on the solaris Server?
2. please send me the steps to extend the file system.
3. do i need to check something before.
Best regards

Hi!
Extending the filesystem should be pretty straightforward. If this is your first time, you might want to perform the steps in the the web GUI. Login to the web interface for your control station and select Filesystems from the left-hand menu:
Simply select the filesystem you want to extend, right click on it, and select Extend from the menu. You'll see a new window where you can select the storage pool you want to use, how much space to add (in Megabytes) and so on.
You'll see how much space is available in the field that says Extend With Storage Pool. If you have more than one storage pool configured, you should use the same pool to extend your filesystem (you'll see which pool is in use in the Current Storage Pools field). In my case, I'm extending a 10GB filesystem that's on pool clar_r5_economy, with more space from the same pool.
You can also do this from the command line, but this is often the easiest way when you're unfamiliar with the steps.
Let us know if this works for you!

Ah yes, indeed! (Says the man who misplaced a zero and extended a 60GB share to 6TB; I had to delete it and recreate it!)

as Karl nicely showed its really easy as long as you have space available in the pool
nothing to check - no umount or downtime required - completely online
it just takes a couple of seconds at most and your Solaris server will then immediately see more free space
just read carefully that the extension size is specified in MegaBytes (not GB)

I did that on a production file system, had to migrate customer to another (smaller) file system

This post was really helpful but my issue is that the filesystem is being replicated to another location. Can anyone tell me how I extend a file system in this case?

have you since added more space to destination array ?

Curious to know what we can do in this situation.

Yes, I did add space to the destination array.

same process, when you extend source file system, replica file system gets extended automatically. Just make sure you have enough space on the target Celerra/VNX.

You only need to have space available to extend the filesystem in the same type of disk configuration - the extend operation is online and quick - no effect on any data or user access.
However, it is recommended that, you don't mix up the storage pools in the process of extension - i.e. try NOT to extend a file system using clar_r5_economy pool where the file system was originally created on clar_r5_performance pool.
You can not mix the file systems of different disk type - i.e. can not extend a file system created on FC disks to SATA disks. The extend option will show you only available storage pools.
My 2 cents
Thanks,
