Hello I hope everyone is having a good day!
Situation:
2540 with 3.6TB of usable space
volume A is 2.6TB
volume B was 1TB
Volume A is mounted via a single lun on a solaris server and is running out of space.
Volume B was used on another server but is no longer, I deleted the volume in CAM.
Is it possible for me to expand volume A with what was in B and then expand the zfs file system on volume A's server without losing the data on its zfs pool?
Please help, thanks!
Can you explain more ..
I thought it was pretty explanatory.
What else would you like to know?
Attach the "volume B" as another LUN to the solaris server and then add it to ZFS pool using "zpool add".
And the pool is only a single device as it is, so this would concatenate correct?
is this the only way? Thanks btw
Yes. It will concatenate those devices. It is the safest/most reliable way.
Thanks bartus, i went that route. Like you said it is the easiest. Besides the 2540 is managing the raid5.
Do you know of any issues with having a zpool with a single device lun coming from a 2540 that is already a raid5 device?
Well... Sometimes performance may suffer if you use one or two huge LUNs (more than 1TB) for your zpool. It depends on how busy is your application. If you don't see any "slowness", then you don't have to bother with optimizing that.
