Migrating data from Trad vol to...

RE: No spare disks for root

Hi,

I currently administer a FAS 940 and the vol0 volume has been assigned 5 disks giving it a total of 191GB of space however only 3% of this is used so in effect 3 of the disks are wasted. Is there anyway to remove 3 disks from this volume? the filer is running ontap 6.5.6 so we are not using aggregates.

Regards

Hi,

According to me you cannot take away disks from a traditional volume. So the only way to schrink the volum is migrate the data to another traditional volume created on less disks.

Best regards, Rik Daniëls

No. You will have to copy vol0 off to another location (new vol w/fewer disks), then destroy original vol0.

Hi,

There's no way to do it without downtime, and it will be tricy if you have less that 2 spare disks. If you have at least 2 spare disks, you can do as follows:

1. create a new volume, say /vol/root 2. vol restrict /vol/root 3. vol copy /vol/vol0 /vol/root 4. vol online root 5. vol options root root 6. reboot

Or, if you want the new volume to be named vol0,

6. vol rename vol0 vol0_old 7. vol rename root vol0 8. reboot

After the reboot make sure everyting is working OK. Remove the old volume:

1. vol offline vol0_old (or vol0 if you didn't rename the old volume) 2. vol destroy vol0_old

New subject: Ontap 7 Upgrade.

We are planning to upgrade our clustered 940 filers from 6.5.6P3 to 7.2.3.

We had netapp run an Upgrade Advisor for us.

I would appreciate any comments/suggestions on upgrading to 7. We are running 7 on a couple of 3050's that were shipped with 7, but we haven't upgraded any systems from 6 to 7. Any gotcha's that anyone is aware of?

We only use these systems for CIFS and NFS.

Thanks,

Jeff.

How many disks? I'm assuming FC disk.

Make sure you don't update your disk firmware before upgrading Data ONTAP. The now site mentions bug ID - 113823, so do some reading on that. Also expect some temporary performance degradation when you do the disk/shelf firmware upgrade (this is not the same as upgrading Dataontap. Disks, and shelves all have their own firmware revisions you need to look out for). The disk upgrade itself can take 2-3 min per disk drive.

You're going to love the improvements from a 6->7 upgrade though. Auto delete snapshots, and flexvols = your friend.

As long as you have NetApp involved you should be covered.

Good luck!

Yes to performance degradation related to disk firmware. Shelf firmware is not just performance impactful but disruptive as this process will take whole shelves offline while it upgrades the controller firmware. Figure 2-3 minutes per controller (Multiplied times # of controllers) If I remember the last time I did this.

Also there will definitely be a I2P (inode to parent) initialization, which depending on how much data you have can take long time. See page 32 of the upgrade guide for more information

http://now.netapp.com/knowledge/docs/ontap/rel723/pdfs/ontap/upgrade.pdf

The aggr/vols going through this initialization will be online but again it will cause some performance degradation. I believe the upgrade doc includes this information but you can monitor the status by the following commands:

priv set advanced wafl scan status

I second involving NetApp support. Regardless of how large or small my upgrade/change, I always place a call into NetApp to run through all possibilities.

Their support is best in the industry, IMHO.
